Changelog

0.7-alpha — 2026-09-29

The lists below are not exhaustive — they pick the changes a
player is most likely to notice.

The project is now called OpenCol; the
binary is opencol.

Rival European AI plays properly: it expands, its colonies pick real build
projects, its Pioneers plow, clear and road, and its ships no longer idle in
Europe or circle the map. [953] [954]
AI colonies seat workers sensibly — food tiles get farmers and fishermen,
building jobs are not abandoned, and colonies stop starving for no reason.
[562] [567] [568] [569] [572]
Braves attack units caught in the open instead of standing next to them, and
raids burn the lowest owned building tier as the original does. [822] [925]
Factory-tier production math matches the original when inputs run short —
Rum, Cigars, Cloth, Tools and Muskets. [897] [910]
Coastal forts no longer fire on neutral or allied ships. [465]
Treasure Trains need the right Galleon capacity and cash in correctly,
including the King's transport offer. [484] [736] [738]
Veteran Dragoons harden into Continental Cavalry, not Continental Army. [534]
Founding Father effects corrected (Bolivar, Brebeuf, Las Casas, Pocahontas);
more invented effects removed. [476] [477]
Trade routes actually carry their configured cargo instead of running empty.
[949] [982]
Wagon Trains can no longer board ships. [482]

Damaged and sunk ships pixelate away inside the dissolve animation, whether
the kill came from combat or from a coastal fort. [462] [464]
Your own winning unit no longer plays the death dissolve. [533]
Map draw order fixed so plowed fields sit correctly under roads and rivers.
[622]
Units outside a colony keep the original's fixed position as the
fortification is upgraded. [536]
Damaged Artillery uses its damaged icon, and the sidebar shows a repair
countdown instead of a stale order letter. [763] [705]

Every sound cue in the original was traced and wired: combat now picks the
attacker- and defender-specific shot, loss and sinking cues, native attacks
get their own stings, and colony, Europe, mission, tea-party and raid events
all fire the right sound.
Title-menu music is back — the menu opens on the Natives theme and then
cycles tunes like the map does.
The three original option flags (Background Music, Event Music, Sound
Effects) now gate exactly what they gate in the original.
Scout and native-encounter cue order fixed. [502] [729] [765] [849]

Report screens repaired: Religious, Congress, Economic and Naval Adviser had
wrong fonts, missing columns and mis-formatted numbers. [973]-[979]
Popups that showed blank choice labels now show their text, and a batch of
invented English popup strings was replaced with the original's own text (or
removed). [541] [542] [543] [983]-[990]
Unit and sidebar names corrected, including Continental Cavalry showing as
"Soldier". [538] [591]
Diplomacy text no longer substitutes a nation name for a leader's name. [468]
[474]
The colony jobs popup lists indoor jobs, not just the nine field jobs. [900]
Trade route editor regained its table headers; long cargo names stop
overflowing. [945] [946]
Simultaneous fortress fire resolves one combat at a time instead of stacking
every announcement ahead of every result. [535]
"This unit cannot attack" no longer wedges input during a Go To. [469]

Optional message log strip under the screen (display.window_log_lines in
settings.json, 0-24 rows) keeps the popups you just dismissed readable.
Placing a colonist from the fence picks a job that makes sense for the tile.
[944]
Sentried units wake for approaching enemies, including REF landings. [539]
Popups raised inside a colony are no longer held back by a detour to the map
or the Colonopedia, and the docks-required warning appears at once. [950]
[951]
Confirmation prompt restored before attacking a village on reduced movement.
[940]

Save/load: a long list of state that used to reset on reload now survives —
cargo on trade-route carriers, ships' passengers, Brewster's immigration
filter, and more. [972] [981] [982]
The original's music driver is emulated rather than approximated, so song
selection and the tune pools behave as the DOS build does.
docs/known_divergences.md records the deliberate differences from the
original, so they stop being re-reported as bugs.
The largest source files were split by feature (AI, colony, Europe, units,
reports, turn, game loop) with matching test targets.
