-### Breaking changes
+## v0.2.0 - 2026/10/21
 
 ### Added
 
+- Follow the operating system's native theme on macOS, Windows and Linux (KDE, GNOME), applying the OS colors, fonts, radii and accessibility preferences.
 - Add an identity import dialog, importing an existing identity by pasting its `nsec` secret key (encrypted with a new passphrase), NIP-49 `ncryptsec` (unlocked with its passphrase), or `bunker://` NIP-46 URI
 - Add a dropdown menu on the signed-in user button in the sidebar
 - Add sign-out feature, confirmed by an alert dialog before deleting the stored session credential
@@ -13,9 +12,11 @@
 - Allow choosing the default branch when publishing a repository
 - Detect when local commits are not on Nostr yet, showing an unsynced count badge on sidebar repository rows and a Sync now banner on the repository view
 - Add a step-by-step push checklist while publishing and syncing a repository
+- Add a `Reset remote to local` action that republishes the mirror and deletes grasp refs the mirror does not have
 
 ### Changed
 
+- Use the built-in light/dark syntax highlighting palette instead of the Signed palette bundled in `signed.json` when the native theme is active
 - Increase the default theme corner radii from 2 to 4 and large radii from 6 to 8
 - Surface backend errors as error notifications in the workspace instead of silently dropping them
 - Break ties in repository activity lists by event id, so same-second events order deterministically
@@ -26,19 +27,23 @@
 - Restructure the core crate into focused modules for announcements, pull requests, git events, inbox, and upstream state
 - Publish nostr events directly through the client with relay acceptance required, removing the grasp push helper and its per-server retry loop so failures surface immediately
 - Poll the repository sync drift check every 180 seconds instead of 60
+- Track sync status per view instead of globally
 - Merge the `PixelAvatar` into the `Avatar` component. Seed user pixel avatars from the public key instead of the display name, so avatars stay stable when a user renames
 
 ### Fixed
 
 - Fix the repository view refreshing its mirror from the network while a push is in progress, so the refresh no longer races the push
+- Fix opening a repository failing with a `destination already exists` error when two loads raced to clone its mirror, clones are now serialized and later loads reuse the finished clone
+- Fix a repository never opening again after an interrupted clone left an unusable mirror directory behind, which is now removed and re-cloned
 - Fix signing in with a `bunker://` URI silently generating a new identity instead of erroring when its master key cannot be parsed
+- Fix repository sync failing with `state event in purgatory ... doesn't match push` when grasp servers hold branches or tags the local repository lacks
+- Fix sync failing with `could not fetch refs/tags/...^{}` on repositories with annotated tags, where the peel entries `git ls-remote` reports for annotated tags were mistaken for missing refs
 
 ### Removed
 
+- Remove the light/dark theme pickers and the font size, corner radius, focus ring and shadow settings from the settings dialog; colors and geometry now come from the native theme
 - Remove dead code: the unused `login`/`logout` family, the unwired `SyncProgress` pipeline, `merge_pull_request`, inbox mark-read/archive APIs and the wasm32-only code paths
