GUNFIGHT AT THE O.K. CORRAL - CHANGELOG
Entries are kept from every release, newest first.

VERSION 1.3.0
Release Date: September 25, 2026
First Tronsoft Games Portal package (Package Specification v1.6.2).

ADDED
- Packaged to the Tronsoft Games Package Specification v1.6.2: manifest, storefront art, four screenshots, manual, tutorial, credits, licence, self-tests and a developer-side validator.
- Keyboard play of the whole game: Shift+arrows move a cursor over the map, Q jumps to the next enemy in sight, Enter moves to or fires at the cursor square; Tab reaches every button with a visible focus ring.
- Sound volume in four steps (100%, 60%, 30%, off) in place of on/off.
- Fullscreen button in the View row.
- Recorded sound effects in sounds/ (rendered from the game's own synthesized recipes); the game falls back to synthesis if a file cannot be loaded.
- The replay now shows the roster as the men stood at each step, not as the fight ended.

CHANGED
- Browser storage moved into this game's namespace: tronsoft_gunfight_at_the_ok_corral_save and tronsoft_gunfight_at_the_ok_corral_prefs. Saves and settings under the v1.0-1.2 keys are moved across once, on first launch.
- The computer opponent now lives in its own file (js/ai.js), and every modifier, cover value, nerve, wound, surrender and scoring number lives in one exported table that the rules, the manual and the tutorial all read. Play is unchanged: 1,800 fights across all ten scenarios replay shot for shot identically to v1.2.0.

FIXED
- Pressing Enter or Space on a focused button no longer also triggers the matching keyboard order.

SAVED GAMES
- Save format 1 is unchanged. The storage keys changed; older saves are migrated once. A save written by v1.3.0 cannot be read by v1.0-1.2, which look under the old keys.

VERSION 1.2.0
Release Date: September 24, 2026
Iron Springs, random skirmishes and the Tactics Primer.

ADDED
- Iron Springs, March 24, 1882: Wyatt Earp's posse against Curly Bill Brocius's camp, with trees, rocks, brush and a spring.
- Skirmish in a Strange Town: a fictional marshal and three deputies against a gang of five in a town laid out fresh for every fight.
- The Tactics Primer: five lessons with objectives (Reading the Odds, Cover to Cover, Fire and Movement, The Flank, Breaking Nerve).
- Men walk square by square along their route; the walk respects reduced-motion settings.

CHANGED
- Each scenario has its own map; the header names the place and date.

VERSION 1.1.0
Release Date: September 24, 2026
Covering fire and the tools for learning the ground.

ADDED
- Hold fire, covering: a snap shot at the first enemy who fires, or once the fight has begun moves, in sight.
- Threat map, ground readout, Advise me and Undo the move.
- Three opposition levels (Greenhorn, Gunhand, Shootist) with par measured for each; save and resume; after-action replay.

VERSION 1.0.0
Release Date: September 24, 2026
First release as a single HTML file.

ADDED
