v1.0alpha1

v1.0a1 (release 2019.12.07):

GAME CONTENT CHANGES:

• Endgame requires a lot less grinding (emh, Xenega)
• New early-midgame bases to make the progression into the
  midgame more smooth (Xenega)
• All CPUs have been rebalanced. Notably midgame CPUs have
  a much better cost/effeciency ratio and endgame CPUs have
  been nerfed considerably (Xenega)
• New security and reactor items are now available
  (Xenega)

USER-VISIBLE CHANGES:

• Show standard costs and detection chances of items and bases
  in the Knowledge screen excluding any location modifiers
  (Xenega)
• Show location modifiers more prominently in the location screen
  and the dialog for constructing a new base (Xenega)
• Show difficulty setting and in-game time for new savegames
  (Xenega)
• Loading an old savegame (e.g. from 0.30c) will now
  retroactively apply the game data from the latest version
  of Singularity - including making new game content
  researchable (Closes: #56, #122, #145) (nthykier)
• Unify multiple messages into a single dialog with multiple
  pages. This new dialog also supports resuming the game
  instead of forcing the game to be paused (Xenega)
• Events can now expire and two non-unique events now do.
  Previously, they could reappear continously possibly
  making the game almost impossible (or completely
  neutering the affected group) (nthykier)
• The cash display now shows the expected cash change over
  the next 24 hours next to the current cash. Likewise, the
  CPU display includes how much spare CPU there is after
  maintenance and construction. These numbers also include
  purchases currently under consideration
  (Closes: #21, #100) (nthykier)
• Support searching for a savegame by name in the Load
  dialog (nthykier)
• Make the base type and its total CPU visible in the list
  of bases at a given location (Closes: #64) (nthykier)
• Fix a crash when savegame names contained non-ASCII UTF-8
  characters (Closes: https://bugs.debian.org/718447)
  (nthykier)
• Fix visual lag at the highest game speed due to recalculating
  the "day/night" layers (nthykier)
• It is now possible to use double-click as a short-cut for
  "Open base" when viewing the list of bases at a Location.
  (nthykier)
• Base purchase screen now provides more details about the base,
  including accurate purchase and maintenance cost plus detection
  rates (at the level the player is allowed to see them)
  (Xenega)
• Ensure that CPU allocations are re-allocated properly when the
  player loses too much CPU at a given danger level (Closes: #103)
  (Xenega)
• Have a separate volume bar for music and sounds (Closes: #90)
  (Xenega)
• Use the XDG Base Directory Specification on relevant platforms
  (Closes: #53) (Xenega)
• Support deleting existing savegames via the Load screen
  (Closes: #48) (Xenega)
• Select the amount of CPU at the same dialog as the CPU selection
  dialog (Xenega)
• Add new "nightmode" theme (Closes: #119) (cryptarch)
• Theming support to change background image, colors, fonts, etc.
  The themes can have language specific content (e.g. fonts better
  suited for the given language) (MestreLion, Xenega)
• Support changing language without restarting the game
  (Xenega)
• Add warnings for some common issues such as when the player only
  has one base left or that when changing CPU of a base will remove
  existing CPU (Closes: #17) (Xenega)
• Support renaming bases (Xenega)
• Add a 24-hour finance report (Xenega)
• Fix various bugs in the shown detection rates (juise)
• The game now records a log of the latest events that happened
  (Xenega, nthykier)
• Fix issue where build times were affected by game speed (Closes: #18)
  (Xenega)
• Singularity no longer proposes resolutions larger than the detected
  display size and now defaults to 1024x768 as the new default
  (MestreLion)
• Persisting changes in the Options is now automatic on "OK"
  (MestreLion)
• Limit total amount of cash to avoid overflow (Closes: #110)
  (MestreLion)
• Use 2 decimal places when displaying cash or CPU for large numbers
  (MestreLion)
• Reset music when starting a new or loading an existing game (Closes: #100)
  (MestreLion)
• Fixed techs being reset if language is changed mid-game (Closes: #99)
  (MestreLion)
• Saved games list now sorted in in-game load dialog (MestreLion)
• Fixed events not being translated when language changes in-game (Closes: #128)
  (MestreLion)
• Fixed --singledir and --multidir being ignored for saves, preferences, music
  and error log. Also, if possible (Python >= 2.6), error.log is now created
  only when (and if) an error actually occurs (MestreLion)
• Added Brazilian Portuguese (pt_BR) translation (Closes: #130)(MestreLion)
• Updated es_AR translation (Closes: #20)(justapawn)
• Try to use user's locale, or a similar language, as game language (MestreLion)
• Launcher for Linux is now "singularity"
• Revamped Options screen, including new resolutions (MestreLion, Xenega)

OTHER CHANGES:

• Refactored code into a top-level module called singularity instead of using
  generic top-level python modules nad improve setup.py to be setuptools
  compatible (Closes: #12) (rardiol)
• New savegame format based on JSON to avoid a savegame format that can include
  arbitrary code execution via Python's pickle module. Please note that any old
  style savegame will still trip the picke-based codepaths already in the
  savegame listing to simplify the process for players upgrading from 0.30c
  (Closes: #52) (nthykier)
• Add basic documentation of the data files in the docs/ folder of the Github
  repo (nthykier)
• Work around a file descriptor "leak" in Pygame. This fix requires Pygame
  1.9.2 or later to fully plug the leak (Closes: #156) (nthykier, Xenega)
• Add a small test suite and CI testing to catch trivial mistakes earlier
  (nthykier)
• Port the game to run on Python3 (Closes: #15, #169) (Rardiol, nthykier)
• Include a singularity.desktop file (Matthias Mailänder)
• Fix crash related to large font sizes (MestreLion)
• Created .gitignore and .gitattributes files to aid development (Mestrelion)
• New i18n and hotkey approach. E:S is now fully translatable (MestreLion)
• New tools under utils/ dir (MestreLion)
• Use ~/.config/singularity for preferences dir, in a backward-compatible way
  with previous releases: if ~/.endgame is found it is used instead (MestreLion)
• Added ~/.local/share/singularity/music as additional source for music, with a
  symlink in preferences folder pointing to it (MestreLion)
