Version 1.13.8+dev:
* Campaigns:
* Secrets of the Ancients:
* Fix delay when additional enemies appear in S21 (issue #1706)
* Language and i18n:
* Updated translations: British English, Italian, Polish, Scottish Gaelic,
Slovak
* Lua API:
* Add wesnoth.format function to substitute variables into a string.
* Add wesnoth.format_conjunct_list and wesnoth.format_disjunct_list.
* New global "wml" table groups together all the functions for working
with WML tables, and its subtable "wml.variable" groups functions
for working with WML variables. Most of these are functions previously
found only in helper.lua; they no longer need a require to use.
* Warnings for using deprecated Lua functions now only appear in debug mode.
* Multiplayer:
* When set to remember your password, Wesnoth now encrypts it. It is still
possible to obtain the password from preferences, but it's no longer as
trivial as before.
* User Interface:
* Unit recall dialog now sorts the units by both level and required XP for
their next level-up (issue #1738).
* Enable the use of tab to switch between text fields in most dialogs.
* Color-code modifiers in trait tooltips
* Translation teams in credits are now listed in alphabetical order of the
localized language name (rather than the English language name).
* Allow deleting saves with the Delete key in the Load dialog.
* Fixed team selection screen often ignoring attempts to scroll (bug #1632).
* Miscellaneous and Bug Fixes:
* Add --report/-R command line switch for printing the same report from the
Game Version dialog's clipboard function to stdout.
* WML Engine
* If ai_algorithm is used in [modify_side][ai], it now replaces the whole AI
with the contents of [modify_side][ai], instead of appending these parameters.
* New [credits_group] tag can be used by non-campaign addons to group several
[about] tags under a single header. This is a toplevel tag, not a subtag
of [era] or [modification].
* An empty id key in SUF no longer matches all units; instead, it matches none.
Version 1.13.8:
* Campaigns:
* Son of the Black-Eye:
* Balancing changes for 'Silent Forest'.
* Under the Burning Suns:
* New sprites for Quenoth Youth (Kaleh and Nym) and Human Commander.
* Applied a color shift to the human units in S8 and S9 to give them a more
unique look.
* Editor:
* Fixed a crash when placing units.
* Restored the ability to preview different ToDs. Note this still does not
work when invoked form the Custom ToD window.
* Fixed editor sides not having the correct side number.
* Redesigned Windows, Areas, and Sides menus.
* The Windows menu will now display maps starting from 1 rather than 0.
This is likewise reflected in the default map filename.
* Scenario names are now displayed in more places if available.
* Formula Engine:
* Fixed garbage data showing up in stack traces in the event of an error.
* Object types can now be used in contexts where previously only a list or
map was accepted - for example in the filter() function. They will be
treated as a map in such cases.
* Graphics:
* Fixed items not receiving ToD lighting.
* Portraits for many Walking Corpse and Soulless race variants.
* New animations: Dwarvish Fighter idle.
* Language and i18n:
* Updated translations: British English, Chinese (Simplified), Lithuanian,
Slovak, Spanish
* Lua Engine:
* Add wesnoth.log_replay which exposes a little-used functionality of
injecting arbitrary logging data into a saved game.
* Small change to animator API - facing parameter replaced with target and
required to be a space adjacent to the unit.
* New modifiable theme attribute in wesnoth.game_config
* New wesnoth.zoom() function allows changing the zoom level
* The wesnoth.scroll function scrolls the screen by an offset, similar to
[scroll]. For example, wesnoth.scroll(5, -2)
* New is_local attribute in side proxy table allows you to detect whether
or not the side is controlled by a network player. Note that use of this
has the potential for OOS errors.
* New wesnoth.music_list table which allows controlling the music playlist:
* wesnoth.music_list[1] etc returns mutable information about a specific
track on the playlist
* #wesnoth.music_list counts the number of tracks on the playlist
* wesnoth.music_list.current returns mutable information about the
currently-playing track
* wesnoth.music_list.current_i returns the index of the current track on
the list. It is writable, allowing you to switch to any track on the
list. This respects fade values.
* wesnoth.music_list.all returns a copy of the playlist that can be
stored in a variable.
* wesnoth.music_list.play plays a specific track (as [music]play_once=yes)
* wesnoth.music_list.add appends a track to the playlist (as
[music]append=yes)
* wesnoth.music_list.clear clears the current playlist
* wesnoth.music_list.next fades out the current track and moves to a new
track on the playlist
* wesnoth.music_list.force_refresh forces any pending playlist changes
to be immediately applied
* wesnoth.music_list.volume attribute gets/sets the current music
volume, as [volume]music=
* Each track has modifiable shuffle, once, ms_before, ms_after
attributes and read-only append, immediate, name, title attributes.
They are also comparable with == or ~=
* wesnoth.set_music is now deprecated, in favour of the above new API
* New wesnoth.sound_volume function gets/sets the current sound volume, as
[volume]sound=
* New wesnoth.show_story function launches the storyscreen viewer
* wesnoth.dofile now forwards any excess arguments to the file in the
"..." argument
* wesnoth.require can now load all modules in a directory and accepts some
shortened paths, for example omitting the ".lua" file extension and
searching in the current directory.
* When you require a package that has no return value, you now get a table
that errors on any access to it, rather than nil.
* New wesnoth.create_weapon function to make a weapon that's not attached
to a unit (which could be useful for animations)
* New wesnoth.show_message function shows a simple alert dialog, possibly
with a choice
* New wesnoth.alert and wesnoth.confirm functions - simple shortcuts for
the above.
* Functions for working with hex locations have been added under wesnoth.map
In particular, helper.distance_between is deprecated in favour of
wesnoth.map.distance_between
* The following existing functions now also work in plugins and map
generators: wesnoth.log, wesnoth.get_time_stamp, wesnoth.get_image_size
* Several error messages now point more accurately to the actual location
of the error.
* wesnoth.simulate_combat output has additional keys:
* untouched (in first two return values) indicates whether the unit took
any damage
* number (in second two return values) contains the Lua index of the
attack, as opposed to attack_num which contains the WML index.
* weapon (in second two return values) contains the actual weapon userdata
* New methods in location_set: of_triples, to_triples, random
* New animations key in Lua unit proxy returns a list of defined flags for
animation
* New functional.lua file implements a number of higher-order functions
from WFL
* The length operator now works on translatable strings, returning the
length of the translation.
* wesnoth.set_side_variable and unit.variables can now clear variables
* helper.get_variable_array and helper.set_variable_array now work on
units and sides (pass a unit, side, or side number as an extra parameter)
Note: helper.get_variable_proxy_array does *not* work on units and sides
* helper.rand now has a second parameter that defaults to wesnoth.random
* Add wesnoth.game_config.victory_music and wesnoth.game_config.defeat_music
setters
* Add wesnoth.game_config.scenario_id getter
* wesnoth.set_next_scenario() was replaced with
wesnoth.game_config.next_scenario setter/getter
* wesnoth.set_dialog_value can now (un-) fold GUI2 tree view nodes
* Multiplayer:
* Fixed statistics being lost when reloading an MP game.
* Performance:
* Greatly speeded up switching between add-ons in the add-on manager

* Lua API:
* New wesnoth.set_side_id function can change flag, color, or both; it automatically
updates cached flag info for you (but you may still need to redraw to see it).
* The wesnoth.place_shroud and wesnoth.clear_shroud functions can alter shroud data
for a single side. They accept a list of locations, a shroud data string, or the
special value "all".
* New wesnoth.is_fogged and wesnoth.is_shrouded calls test the visibility level

would not attack them.
* New Micro AI: Assassin Squad AI
* Fix bug #23720, AI units with max_moves=0 do not attack.

* Correctly and consistently deal with invisible units
* New ai_helper functions get_attackable_enemies, get_visible_units,
is_attackable_enemy, is_incomplete_move, is_incomplete_or_empty_move,
is_visible_unit and robust_move_and_attack
* Renamed function ai_helper.to_triple to LS_to_triples for consistency

robustness and speed
* Campaigns:
* Eastern Invasion:
* Fixed broken village encounters.
* Tweaked the balance of Scenario 2.

* New wooden floor variation and transitions.
* New aquatic encampment.
* New aquatic castles.
* Reworked stone walls so they take up less space and improved transitions.
* Added Wooden and Rusty Gates.
* Improved connections between castle and wall terrains, allowing castles and
keeps to be placed adjacent to walls without glitches in most cases.

* Tweaked colors for all time schedules.
* Language and i18n:
* Updated translations: Finnish, Polish, Russian
* Lua API:
* Upgrade to Lua 5.3.3+
Consult http://www.lua.org/ for a full change list and updated documenation.
* bit32 functions removed
* utf8 support added
* Added new function wesnoth.fire_event_by_id to fire an event with a given ID.
* Added new function wesnoth.remove_modifications, which removes applied
modifications of the chosen type from a unit. The most efficient use is to
remove all modifications with a specific duration value.
Also callable as u:remove_modifications.
* The built-in conditionals have_unit, have_location, and variable are now
present in the wesnoth.wml_conditionals table. This means they can be
directly called, extended with new features, or even overridden with custom
implementations.
* New recall_filter field in unit proxy returns the [filter_recall] config
* New variations field in unit_type proxy returns a list of unit variations
Each member is a full unit_type describing that variation.
The table is iterable with pairs().
* Lua side, unit_type, and unit attack proxies can now be compared with ==
with identity semantics. (Previously, each time such a proxy was obtained,
it would produce a new object that did not compare equal to any others.)
* Lua unit_type lists (wesnoth.unit_types and unit_type.variations) are now
countable with the Lua length operator.
* Lua dialog functions now support the stacked widget and the unit preview pane
* New wesnoth.show_menu function shows a dropdown menu at the mouse location
* Lua attack proxy has new read_only field which is true for unit_type attacks
If true, attempts to change the attack will result in an error.
* The name field in Lua attack proxy is now writable
* The attacks field in the Lua unit proxy is now writable
Specifically, attacks may be replaced, appended (by assigning a new ID or
the next valid index), or removed (by setting a field to nil).
* wesnoth.show_message_dialog supports second_portrait and second_mirror keys
in its first argument, which produces a dialog with two portraits.
* The callable userdata returned by wesnoth.textdomain can now be called with
an additional two parameters (a plural string and a count) in order to support
gettext plurals.
* New matches function in team and unit attack metatables, which test if the
side or weapon matches a filter.
* helper.lua metatables are now protected from external access; getmetatable()
will return a descriptive string instead of the metatable.
* ai.aspects.attacks no longer returns a full attacks analysis. Instead it
returns a table with "own" and "enemy" keys containing the valid units
for attackers and targets. The function ai.get_attacks() still returns the
full attack analysis.
* Aspect fetcher functions (eg ai.get_aggression()) are now deprecated in favour
of the ai.aspects table.
* The location_set iter and stable_iter functions can now be called with no argument.
In this case, they return an iterator suitable for use in a for loop.
* New wesnoth.wml_matches_filter function takes a WML table and a WML filter and tests
if the table matches the filter. The filter syntax is as with [filter_wml].
* Music and sound effects:
* Added a preference to pause the music when the game loses focus.
* Now the music fades out between scenarios.
* Networking
* Ported campaignd to use boost.asio instead of SDL_net.
* Removed unit tests for old networking stack. This was the last part that
depended on SDL_net
* Performance:
* When a heuristic determines that it's probably faster, the game predicts
battle
outcome by simulating a few thousand fights instead of calculating exact
probabilities. This method is inexact, but in very complex battles
(extremely high HP, drain, slow, berserk, etc.) it's significantly faster than the
default damage calculation method.
* Units:
* Changed the sound for the melee attack of the
Loyalist Bowman, Orcish Crossbowman and Orcish Slurbow.
* User Interface:
* Trait descriptions in the help are now generated. (This makes user-defined
traits show up in the help as well.)
* Fix game map sometimes showing and buttons sometimes not rendered properly
in story screen (bug #24553)
* Improved font rendering on Windows.
* Redesigned gamestate inspector window.
* Recall dialog no longer shows units that no leader on the map can recall
(due to the [filter_recall] not matching)
* Weapon specials only gained through AMLAs now get a help topic
* The "Cores" button on the title screen is now hidden if no cores other
than the default are installed
* Redesigned game dropdown/context menu appearance
* New categories bar in hotkey preferences allows you to filter hotkeys
* Fix issue with the title screen not redrawing when the window size or
fullscreen setting changes with a dialog open over it.
* Restored descriptions for choices in combobox-based Advanced Preferences
entries (lost in 1.13.3).
* When using the --wconsole option, the game now prints a prompt in the event
of a fatal error to avoid closing the console before the error can be seen.
* Restored GUI2 textbox selection highlight lost in version 1.13.3.
* Added a "Draw Number of Bitmaps" option to the map editor, for terrain
graphics diagnostics.
* Ported file chooser dialog to GUI2, and redesigned it to include a
bookmarks bar with predefined and user-defined shortcuts.
* Tweaked the border/groove color scheme on textboxes and sliders to better
reflect their state and mimic window and button borders.
* The following dialogs have been converted to GUI2: Unit Recall, Unit List,
Game Stats, MP Create, MP Game Lobby, Faction Select, Unit Advance.
* Improved UI responsiveness.
* Tab completion in the Lua console is improved. It can now handle paths
containing square brackets (though it won't complete them) and will not
offer keys that are not valid identifiers.
* WML Engine:
* Added ignore_special_locations=yes|no, default no, to [terrain_mask] to
ignore the special locations given in the mask, leaving all those on the
underlying map unchanged.
* [terrain_mask] starting locations and special locations are relative to
the mask. Existing names replace any in the underlying map regardless of
their location. Each name as a unique location; but a location may have
any number of names. While a map/mask can give only one name per location;
stacking masks allows multiple names. Names cannot be removed.
* Added {HAS_NO_TURN_LIMIT} macro for objectives
* New attributes for [message] with [option]
* Added variable= to [message]: if specified, gives variable name to
receive the [option] index (1..n) selected
only used if any [option] appear
* Added value= to [option]: if specified, gives value to store in variable
instead of index number, only used if variable= appears in [message]
* New second_unit, second_image, second_mirror attributes for showing two
portraits on a single message.
* New attributes for [role]:
* search_recall_list=yes|no|only(default yes) controls where to look
* reassign=yes|no(default yes) if no, check for a unit and do not assign to
another
* [auto_recall] sub-tag, if assigned to recall list, gives [recall]
attributes (no SUF)
* [else] sub-tag, WML to execute if no unit found for the role
* New help_text= key for [trait] to set the description displayed in the
help.
* Added tag id= [fire_event], which allows raising events by id
* [modify_unit] now understands [effect] tags, which it applies directly.
This replaces the use of [object] with no_write=yes (which will be removed
in the next release).
* Add [object]take_only_once=yes|no (default yes) - if set to no, automatic
tracking is disabled for this object (allowing it to be taken multiple
times even if it has an id).
* New [remove_object] tag which removes applied [object]s from matched units;
it can filter on the entire [object] WML. The most efficient use is to
remove all objects with a specific duration value.
* Renamed [foreach] variable= to array=
* Renamed [foreach] item_var= to variable=
* Fixed several bugs in the name generation of the map generator
* Fixed issues with using [endlevel] in victory/defeat events
* The {MAGENTA_IS_THE_TEAM_COLOR} macro is no longer needed in [unit_type]
It is now the default behaviour unless overridden with the flag_rgb key.
* New key type_tree in unit filters - similar to type, but also matches any
possible advancements of the specified unit types.
* [options][combo] in [scenario], [modifications], etc has been renamed
to [choice] (which is more accurate). The old name still works for now.
* ~ADJUST_ALPHA() image path function now takes a WFL formula. It can access
the following variables: x, y, width, height, red, green, blue, alpha.
It no longer accepts a percentage (use ~O() for that).
* Fixed [rule] in [terrain_mask] ignoring use_old=yes
* Fixed filter returning invalid locations if invalid locations were given
in a variable that was used with find_in=
* Moves cave map generator to lua. scenario_generation=cave is now deprecated and
will be removed soon. The Lua version has feature parity with the old one, but
the syntax is a little different. It supports both map_generation and
scenario_generation.
* Tunnel functionality was expanded and the default behavior was altered in
order to make moves through tunnels consistent with all other moves:
* Vison through tunnels is now possible and enabled by default. It can be
turned off by setting allow_vision=no in the [tunnel] tag.
* Own and allied units on tunnel exits do not block the tunnel any more.
The blocking behavior can be reenabled by setting pass_allied_units=no
in the [tunnel] tag.
* Added text_alignment= key to [story][part] to specify horizonal alignment of
text.
* [set_variable] now supports abs= (absolute value), power= (raise to
power) and root= (extracts root, 'square' is the only value currently
supported) keys
* Individual [terrain_graphics] rotations can now be skipped entirely by
using "skip" in the rotations= list.
* WML macros can now include optional arguments with default values that the
caller can override.
* Miscellaneous and bug fixes:
* A new way to make units invulnerable for debugging: select the unit and type
";unit invulnerable=yes". This method operates by decreasing the opponent's hit
chance to zero: as a result, it doesn't slow down damage prediction unlike the
"increase HP to ridiculous levels" method.
* The ;choose_level command now works in the tutorial and in [test] scenarios
* Fixed a stray ; character appearing pre-entered in the command console.
* Fixed bug in wesnothd that was causing server crashes if game with
multiple network and local players was ran.
* Added a tab to run the wmlxgettext tool to GUI.pyw
* Fixed problem with Spectre's hitpoint bar positioning.
* Fixed crash when unit with planned actions is killed before those actions are
completed (bug #20071)
* Show correct number of attacks in case of swarm weapon special (bug #24978)
* Fixed bug that icons of buttons under the minimap disappeared when the
player opened and closed a menu.
* Correct unit recall count in statistics when undoing a unit recall (bug #25060)
* Add tip to recall units instead of recruiting them if costs exceed 20 gold (recruitment costs)
* Resolve sides in map editor not having a proper side number and subsequently
causing a crash upon editing (bug #25093)
* Avoid rare cases of mini-map producing a divide-by-zero error (bug #25155)
* [filter_vision]: fix bug of filter not matching own/allied hidden units
* Prevent crash on quitting scenario with planned recruits present (bugs #24022/25193)
Version 1.13.5:
* Campaigns:
* An Orcish Incursion:
* Linaera can recruit Mage, and cannot recruit Elves
* Heir to the Throne:
* Add journey tracks for 19c/20b path.

* Added generic portrait for Giant Spider.
* Language and i18n:
* Updated translations: British English, Galician, German, Italian, Japanese,
Polish, Portuguese, RACV, Russian, Scottish Gaelic, Spanish
* Networking:
* Reworked the multiplayer server to use asio functions for networking
operations instead of SDL_net, thus it no longer depends on SDL_net and SDL.
* The client now uses boost::asio for communication with wesnothd too.
* Removed support for SDL 1.2. SDL 2 is now the only supported version.
* Terrains:
* Changed terrain code of Desert Mountains from Mdy to Mdd.
* Editor:
* Allow to set special locations in the editor which can then be read by wml.

* Various design improvements to GUI2 widgets
* New simpler GUI2 loading screen
* New colored cursor graphics
* Fixed Mage of Light halo appearing in the top-left corner of the screen
while the mage is moving (bug #23712).
* Fixed Observers icon appearing behind other top bar items in MP games on
horizontal UI resolutions < 1024 (bug #24455).
* Fixed ToD schedule progress indicator appearing behind other top bar items
on vertical UI resolutions < 600.
* Improved the dialog for choosing what to do when a player leaves in
multiplayer.
* The side overview now also shows allied human sides in sp even if
they aren't discovered yet
* Added an option to disable the loadingscreen animation since it caused
bugs in some configurations.
* Added a gui method to activate loggers (Preferences -> Advanced -> Logging)
loggers activated in the gui print just like loggers activated in the
command line (i.e. messages appear in the console)
* The Lua console screen now has a clear button
* Fix bug #24762: Editor actions are out of sync after resizing.
* Increased the font size for text in buttons.
* Changed unit help topics to use smaller images on smaller monitors.
* WML engine:
* Add color= attribute to [message].
* Add [else], search_recall_list=, auto_recall= to [role]
* Fix some issues with [foreach]
* Fix some issues with backstab-like weapon specials
* Support [effect]times=<integer>
* Add highlight=yes|no to [scroll_to], [scroll_to_unit], [message]
Defaults to no in the first two cases, yes in the third
If yes, the target hex is outlined.
* New ~SCALE_INTO(w,h) IPF which preserves aspect ratio, using bilinear
interpolation scaling.
* New ~SCALE_INTO_SHARP(w,h) IPF which preserves aspect ratio, using
nearest neighbor scaling.
* Support delayed_variable_substitution= in [on_undo], [on_redo]
Note that this means $unit.x and $unit.y may not reflect the unit's
true location, so using [unstore_unit] on $unit may have unexpected effects.
This applies to $second_unit too. The $x1, $y1, $x2, $y2 variables work fine
though, so in most cases they can be used instead. Anything else in $unit
or $second_unit is also fine.
* formula= in SUF can now reference $other_unit via the formula variable "other"
* formula= now supported in location, side, and weapon filters
* Weapon filters now support number, parry, accuracy, and movement_used
* New [has_attack] in standard unit filters; supercedes has_weapon= and
uses full weapon filter.
* lua_function=var.member now works in SUF; however, 'var' still needs to
be a global variable.
* Added new keys name_generator, male_name_generator and female_name_generator
for the [race] tag to declare a context-free grammar to describe how names
are derived
* Modification tags in [modify_unit] now support delayed_variable_substitution
(This means [advancement], [object], and [trait] tags.)
* All looping tags now give an error if they contain no [do] tag.
(They may contain multiple [do] tags, however.)
* Add [message]image_pos=left|right, which mostly supercedes ~RIGHT()
* For [core] authors: New keys for game logo (game_logo, game_logo_background)
* AiWML:
* Filters within [micro_ai] can now use $this_unit, which was previously
impossible due to the config being prematurely parsed.
* Simplified aspect syntax which works for all aspects, present and future:
* All aspects with simple values can be specified as key=value
* Except attacks, all aspects with complex values have a simple tag form
containing only the aspect value (e.g. [avoid])
* All aspects, simple and complex, can be specified using a tag named by
the aspect, whose contents is the same as a corresponding [facet]
* The full [aspect] and [facet] syntax also still works
* [ai] configs no longer recognize the version= key
* ai_algorithm key now selects a preset AI; possible values include
"ai_default_rca", "experimental_ai", and "idle_ai", but custom AIs
defined by eras or modifications with an [ai] tag can also be used
* [leader_goal] now automatically sets facet ID for auto_remove
(Only if using simplified syntax; in full syntax, the ID must still be
specified in two places.)
* The AI config in the gamestate inspector is now split into multiple
sections according to the type of component.
* The following deprecated components have been removed:
* recruitment stage (name=ai_default::recruitment)
* old recruitment candidate action
(name=ai_default_rca::aspect_recruitment_phase)
* old simple move-to-targets candidate action
(name=ai_default_rca::simple_move_and_targeting_phase)
* number_of_possible_recruits_to_force_recruit aspect
* recruitment_ignore_bad_combat aspect
* recruitment_ignore_bad_movement aspect
* The recruitment aspect has been removed from the engine; however,
"recruitment" is now accepted as a synonym for
"recruitment_instructions". Old code should work without changes.
* [goal]name=protect_my_unit
* The following experimental components have been removed:
(Most of these were broken or non-functional)
* Experimental recruitment candidate action
This worked, but was worse than the default recruitment.
* Global fallback candidate action
* Akihara recruitment candidate action
* Fallback stage (functional but useless)
* Strategy Formulation with RCA stage
This worked, but was slow and unmaintained. If a maintainer
steps up, it may be restored later.
* Several of the development AIs available in debug mode in the
multiplayer setup menu
* The "Strong AI" has been renamed to "Default AI (RCA) with Alternate
Recruiting" and is now only available in debug mode.
* Lua components (goals, aspects, stages, and candidate actions)
now support an [args] subtag, which passes any sort of WML data
to the Lua code - this works similarly to [args] in a [lua] tag,
though not quite identically.
* Aspect syntax with [aspect] tag has been fully generalized so that
[aspect], [facet], and [default] are all exactly the same in terms of
what contents they expect. (Except that [facet] additionally takes
turns= and time_of_day=.) The most useful consequences of this:
* You can nest a [facet] inside another [facet] if the outer one has
name=composite_aspect
* You can define a [facet] with the Lua engine
* invalidate_on_tod_change= has been implemented for aspects. It applies
when the bonus resulting from time of day modifiers (excluding any
illumination abilities) changes at any location on the map. Thus, it
occurs on average less often than invalidate_on_turn_start and may
be best combined with an explicit invalidate_on_turn_start=no.
* Minor shorthands have been introduced in the recruitment_instructions
aspect:
* [pattern] tag is like [recruit] with pattern=yes
* [total] tag is like [recruit] with total=yes
* If no [recruit] tag is present, a default is added with importance=0.
This means recruitment will happen even with only [limit] tags.
* Extensions to [modify_ai]:
* [modify_ai]action=change works on aspects, using path=aspect[id].
Useful if you need to change all the facets at once, but note that
it also wipes the [default] facet.
* The [default] facet can be referenced as facet[default_facet].
This should rarely be needed, but is there in case it is.
It also makes them easily identifiable in the inspector.
* Automatically copy over the id= with action=change, if the
new component did not specify one.
* It can add, remove, and change jobs and limits in the
recruitment_instructions aspect. The path to use for this is
aspect[recruitment_instructions].facet[facet_id].recruit[recruit_id].
(For a limit, replace "recruit" with "limit".)
The [recruit] and [limit] tags now support id keys for this.
* Added side_name= attribute in [side], it's now no longer possible to
specify the current_player attribute in the [side] wml.
* unit filters, specially in wesnoth.get_units now have a limit= attribute
to limit the number or matched units.
* Added new attribute "registered_users_only" to MultiplayerServerWML which indicates
that only registered users should be allowed to join the game
* wesnoth now does a stricter check for unit type ids.
* In multiplayer, victory events now fire at the end of the scenario if at least one
human player has won, this fixes OOS in mp campaigns.
* Lua API:
* wesnoth.match_unit can now take a location (rather than a unit) as
the optional third parameter. This will cause the filter to consider
the unit to be on that location instead of its actual location.
This even works for units on a recall list.
* wesnoth.highlight_hex is no longer deprecated, but its effect is
slightly different from the old one. It outlines a hex, nothing more.
* wesnoth.select_hex is now deprecated in favour of the new
wesnoth.select_unit (or u:select). The effect is almost the same
(with the exception that it does not outline the hex if true is
passed as the second argument), but this name change was done to
emphasize that it acts on a unit, more than a location.
* New wesnoth.set_time_of_day function which sets the current time
of day, taken either as the time ID (eg "second_watch") or the index
of the time in the overall schedule (eg, 1 would be dawn in the default
schedule). Optional second argument takes a time area ID, to set
local instead of global time.
* New wesnoth.add_fog and wesnoth.remove_fog functions allow changing fog
on the map. The [lift_fog] and [clear_fog] tags now use this.
* New wesnoth.add_sound_source, wesnoth.remove_sound_source, and
wesnoth.get_sound_source functions to allow manipulation of sound
sources. The [sound_source] and [remove_sound_source] now use these.
* New wesnoth.log function for printing log messages. The [wml_message]
and [deprecated_message] tags now use this.
* New wesnoth.name_generator function builds a name generator and returns
it as a callable userdata. Both the original Markov chain generator
and the new context free grammar generator are supported
* New wesnoth.get_end_level_data() function which can be called in a
victory, defeat, or scenario_end event to access (or change) how
the scenario ends.
* Fix wesnoth.erase_unit failing if the unit was on a recall list.
* WML tables defined in Lua now accept string keys with array values
(where "array" is a table whose keys are all integers). This joins
the elements of the array with commas and produces a single string
value. eg {x = {1,2,3}} is equivalent to {x = "1,2,3"}.
* wesnoth.effects table can now be used to alter the behaviour of
built-in effects - for example, to add a new feature to
[effect]apply_to=attack. It also now supports effect descriptions,
for use by the [trait] tag.
* Additional fields in unit proxy:
* usage, cost - self-explanatory
* traits - list of the IDs of all traits
* abilities - list of the IDs of all abilities
* Additional fields in table returned by wesnoth.get_terrain_info:
* icon, editor_image, light
* Additional fields in unit type proxy:
* race, id, alignment
* attacks, which returns the same thing as unit.attacks
* abilities, same as unit.abilities
* Additional field in side proxy:
* faction (read-only), faction_name (read-only)
* LuaAI:
* The table returned by check_*() now has a "result" field which
gives a description of the action's result; similar to "status"
but more descriptive.
* Target tables now use a descriptive name for "type", instead of
an integer. This applies to the elements of the table returned by
ai.get_targets() and also to the elements of tables returned by
Lua goals. (However, Lua goals that used integers will continue
to work for now.)
* There are some compatibility-breaking changes to Lua candidate
actions - see the release notes or the wiki for full details.
* Lua AI code can now access the AI routines through the global ai
object. This object is only accessible to AI code; it does not exist
in the general Lua global scope.
* When executing Lua goals, aspects, or candidate action evaluations,
the ai is in "read-only" mode - the read_only key is set to true,
and functions that change the gamestate, such as ai.attack(), are
missing from the table. (ai.check_*() functions are still present.)
* The ai.aspects table provides access to every aspect known by the
engine, including several that previously did not have corresponding
ai.get_*() functions. You access them as ai.aspects.avoid, for example.
The table is read-only and raises an error if you attempt to write to it.
* The way to create Lua candidate actions has changed a little. Old code
will require minor changes.
* New wesnoth.micro_ais table contains the loaders for all Micro AIs.
New loaders can easily be installed by add-ons. See any built-in
micro AI (in ai/micro_ais/mai-defs/) for an example of how to do this.
* The attacks aspect can now be defined as a Lua aspect. The code
should return a table with keys "own" and "enemy", each of which may
be either a unit filter table or a function which takes a unit as a
parameter and returns true or false.
* Added wesnoth.game_events.on_mouse_move/on_mouse_actions callbacks
(fr #22635)
* Added wesnoth.special_locations
* [lua] tags now also support the [args] subtag outside events.
* added lua_function= attribute in location filters
* Added on_event.lua which is an eaiser to use wrapper for
wesnoth.game_events.on_event
* Multiplayer:
* Hornshark Island: simplified multiplayer faction determination
* Added "Registered users only" checkbox to multiplayer configuration dialog which
when checked, only allows registered users to join the game
* Wesnoth formula engine:
* Formulas in unit filters can now access nearly all unit attributes
The following attributes were renamed (old names still work, for now):
leader -> canrecruit
total_movement -> max_moves
movement_left -> moves
states -> status
* Nearly all unit type, side, weapon, and terrain attributes available
to Lua code are now also exposed to WFL. The exceptions are mainly
translatable strings.
* Unit and side WML variables are now accessible under "wml_vars".
Since WML variables don't easily translate to formula variables, the
special attributes __all_children, __children, and __attributes provide
specialized views of the variables config as a list, string-list map,
and string-value map, respectively.
* The 'special' attribute of weapons was renamed to 'specials', and it now
contains the special IDs rather than their translateable names.
* New syntax features:
* String interpolation syntax. Within a formula string (enclosed in
'single quotes'), the syntax [some_formula] interpolates the result
of the inner formula into the string. (The simplest use case is
interpolating the values of variables.)
* String can now escape special characters:
['] single quote, [(] open square bracket, [)] close square bracket
* New 'in' operator which tests if a list contains an item or if a map
contains a key.
* New concatenation operator a..b which works on strings and lists
* New range operator a~b which produces a list of consecutive integers
This can also be used for "list slicing" - eg my_list[3~5] returns
a new list containing elements 3 through 5 of my_list.
* Lists can be used as an index for a list. This is "selection indexing"
and returns a new list with only the elements specified by the indexing
list.
* Function definitions (using the def keyword) are now supported in all
formula contexts, which means that they can be used outside FormulaAI.
However, non-FormulaAI functions are currently local to the formula
that declares them.
* Maps containing string keys that are valid identifiers can now be
indexed with the dot operator instead of the indexing operator.
* Strings can now be indexed via 'string'.char[n]. Also supported are
'string'.word[n] and 'string'.item[n] (the latter splits on commas)
* Changes to core functions:
* head() takes an optional argument - if present, a sublist is returned.
* abs(), max(), min() now work on decimal numbers
* reduce() function can specify an optional initial accumulator
This will be returned for an empty list instead of null.
* substring() function can now accept a negative size parameter
This counts backwards from the specified offset
A size of -1 is the same as 1.
* if() can take two arguments; returns null if the condition is false
* tomap() will now invert the effect of tolist()
* debug_print() now shows in chat area if debug mode is on
* New core functions:
* Trig functions tan, acos, asin, atan have been added. (Sin and cos
existed since at least 1.9 but were undocumented until very recently.)
* Other common math functions - root(), sqrt(), cbrt(), log(), exp()
* hypot(x,y) function calculates sqrt(x*x+y*y) with minimal error
* pi() returning the circle ratio
* tail() - opposite of head()
* reverse() function for strings and lists
* zip() function - converts [[1,2,3],[4,5,6]] to [[1,4],[2,5],[3,6]]
* take_while() function returns items from a list until the first one
that fails a condition
* find_string() locates a substring within a string
* replace() replaces a sequence within a string
* type() function checks the type of a formula result
* distance_between() - this was promoted from FormulaAI to core
* pair() function that produces a key-value pair suitable for
passing to tomap() - this also means key-value pairs are now
serializable (relevant in FormulaAI)
* sgn(), trunc() and frac() functions for decimal numbers
* Map generator engine:
* makes now use of the new context free grammar name generator
* ported name generation from english.cfg to [naming]
* Bugfixes:
* Dice operator is now synced (where possible)
* Modulus (%) operator now works on decimal numbers
* Exponentiation (^) operator is now right-associative
* Fix several math operations returning a very large negative number when
the operation was invalid (for example, (-2) ^ 0.5).
Now they return null instead.
* Formula debugger (accessed with the debug() function):
* Now works again, but is skipped unless in debug mode
* No longer explodes on formulas using less-than
* Some better information and formatting in the execution trace
* You can now step through "where" variable assignments
* FormulaAI no longer starts recruiting if a formula evaluates to the
string 'recruit'.
* Deprecated:
* The fai/faiend keywords are deprecated as part of a move to clearly
define the difference between "Wesnoth Formula Language", the language,
and "FormulaAI", the AI engine that uses the language. For now they
still work, but any future code should use wfl/wflend instead.
Use of the .fai file extension is still fine for FormulaAI code;
for other formula code in a separate file, .wfl is recommended instead.
* Miscellaneous and bug fixes:
* Resolve translated logo images not being used (bug #24357)
* Ported the "hexometer" tool from Bash to Python 3
* Recognize hotkey release events
* Allow changing keybindings for scrolling the map.
* Fix the move-to-targets candidate action of the default AI ignoring tunnels
* Fix two rare bugs in the goto candidate action that resulted in goto moves
by other units being skipped after a unit could not get to its goal.
* Replace wmlxgettext tool with new python3 implementation by Nobun:
https://github.com/AncientLich/wmlxgettext-unoff/
* Debug commands that create units now do so for the currently controlled
side instead of always side 1.
* Fixed bug #24696 (Nightstalk ability not working)
* Ported the following scripts to Python 3: TeamColorizer, about_cfg_to_wiki,
campaign2wiki, terrain2wiki
* Wesnoth now ignores unknown arguments that XCode may pass when testing.
Version 1.13.4:
* Language and i18n:
* Updated translations: British English, Russian
