+# Changelog
+
+Kept as the work happens, not assembled at release time. Format is
+[Keep a Changelog](https://keepachangelog.com/en/1.1.0/); versions follow
+[SemVer](https://semver.org/spec/v2.0.0.html).
+
+## Unreleased
+
+## 1.0.0 — 2026-08-08
+
+The first tagged version. `1.0.0` rather than `0.x.x` because the overlay does
+what it set out to do: the database is complete and usable, and the version
+files only said 0.1.0 because the scaffolding did.
+
+### Added
+
+- A desktop overlay for *Kingdom Come: Deliverance II*: a searchable database of
+  console commands, items, perks, buffs and skills. Fill in the parameters, click
+  Copy, paste into the game console.
+- Quick cheats, with the "Set skill level" skill field a select over all sixteen
+  skills rather than free text.
+
+### Changed
+
+- The working notes left the working tree. They were an **untracked** `CLAUDE.md`
+  that existed on one machine only, and are now the
+  [wiki](https://git.houmeres.sk/Houmeres/Kingdom-Cheat-Deliverance-2/wiki).
+  Because the file was never committed, **this repository's history was not
+  rewritten** — there was nothing in it to remove.
+
+### Note
+
+It does not talk to the game. It builds command strings for the clipboard.
