 When a view's state has changed in a way that may affect its rendering, it should call `cx.notify()`. This will cause the view to be rerendered. It will also cause any observe callbacks registered for the entity with `cx.observe` to be called.
 
+GPUI also tracks the entities a window reads while rendering. When an entity notifies, every view that read that entity during the previous frame is rerendered automatically.
+
+* A view that reads an entity in render (e.g. `state.read(cx).profile(...)`) does not need `cx.observe(&entity, ...)` to pick up its changes - the read itself is the dependency. Reserve `cx.observe` and `cx.subscribe` for when the view must run logic in response to a change (rebuild derived state, re-query, dedupe), not to trigger a re-render.
+* Notify the narrowest entity holding the change. Notifying a global store rerenders every view that ever read it; notifying a per-panel entity rerenders only the panels reading it.
+* This works with cached panels (`panel.cached(...)`): a cached subtree repaints when the view it belongs to is invalidated.
+
 ## Entity events
 
 While updating an entity (`cx: Context<T>`), it can emit an event using `cx.emit(event)`. Entities register which events they can emit by declaring `impl EventEmitter<EventType> for EntityType {}`.

 # Changelog
 
-## Unreleased
+## v0.2.0 - 2026/10/21
-
-### Breaking changes
 
 ### 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
 - Add a quit action, bound to `secondary-q` (cmd on macOS, ctrl on others)
 - 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
@@ -23,15 +25,25 @@
 - Connect to grasp relays and load the inbox only after the user's grasp list event arrives
 - Refresh the checkouts store only when the checkouts settings change
 - 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

+### Milestone 1: release the first out-of-box experience version
+Alpha version has been released, I'm working toward the first stable release for the desktop version, which will include a fully git workflow, repository management and collaboration. The stable version will maximum compatible with other nostr git (grasp) client
+
+### Milestone 2: release the web version and mobile apps
+Release the web for browsing and repository management, full git workflow and collaboration still require the desktop app. About the mobile apps, it not only a hub for repositories but also control the agents which will be add later
+
+### Milestone 3: social coding and web of trust
+Implement social layer, each repository can become a community (NIP-29), sharing patch snippets or napplet (NIP-5D) like sharing posts. The web of trust layer will help me user focus on works and support from their circle, provide more information to help user make decision, prevent bad actor can affect the software or supply chain.
+
+### Milestone 4: agent collaboration and workspace
+Support users to plug their coding agents to resolve or review issues, patches, and pull requests. Workspace is a specific environment, allowing users to try new ideas, test a patch in a parallel branch without affecting the main tree.
+
+### Milestone 5: private repository and team collaboration
+Support multiple teammates, channel and communication. Automate turning the discussion into plans and pull requests without hopping between multiple tools.
