* fix(sync): don't delete a local row when the server can't send its copy

A push conflict on a live record whose server row failed to serialize
came back as row: null, deleted: false, and the desktop treated that as
a delete. The server now rejects that op as unavailable, the desktop
never deletes on a conflict without a row, and serialization failures
are logged.

* fix(sync): retry temporarily unavailable records

 # Changelog
 
+## 26.10.2
+
+### Added
+
+- Hide sidebar after opening, in Customize Sidebar, closes the host list once you open a host
+- Sort the dashboard's Host Status card by name, IP address or status
+
+### Changed
+
+- The side menu now opens over the page when it expands on hover, so open sessions like remote desktop are not resized each time. Turn on Push content when it expands in Settings to get the old behavior back
+
+### Fixed
+
+- Picking a section lower down in the host editor, like Warpgate, stuttered on the way and sometimes stopped before it got there
+- Sorting hosts by IP address put 10.0.0.210 before 10.0.0.3
+- The local terminal failed to start in the universal macOS build
+- Hosts shared with you never showed up on a linked desktop
+- A linked desktop could never turn on an unsigned plugin the server had enabled
+- Creating, cloning or deleting hosts failed with "no such table: main.p_vault_profiles" after the Vault plugin was removed
+- Opening a user in Settings, Users blocked the other admin sections until you went back to the user list
+- A linked desktop could keep showing the same sync conflicts, or delete a local host, when the server could not send its copy
+- Usernames are now unique
+- Importing user data keeps foreign keys on
+- Trusted proxy login checks the address nginx saw, not nginx itself
+- The desktop login frame only trusts the server's own origin
+- External login URLs and callback ports are checked on the desktop app
+- A changed jump host key is no longer accepted without asking
+- Synced plugins signed only by a key the server sent are no longer turned on by themselves
+- Two connects to the same host at once could overwrite each other's connection
+- Indonesian uses the same technical terms everywhere
+- When the server was down or still starting, the login page said it could not connect to the database and stopped trying. It now says the server is not responding and continues on its own once the server is back
+- nginx answered 404 instead of 502 while the backend was down
+- A client tunnel that could not start always said "Endpoint SSH connection closed" on the desktop app instead of the real reason, like the target refusing the connection
+- The Docker server crashed and restarted every few hours in ssh2's native crypto on Node 24

 # Changelog
 
+## 1.0.10
+
+### Changed
+
+- `termix-plugin pack` includes the plugin's `LICENSE` and `NOTICE` files, so third-party notices ship with it
+
+## 1.0.9
+
+### Added
+
+- Worker entries in `package.json` `termix.workers`, each bundled on its own into `dist/workers/<name>.js`
+- A `.wasm`, `.ttf` or `.otf` import gives the file's bytes, in `termix-plugin build` and in plugin tests
+
+### Fixed
+
+- The plugin guide listed jszip, guacamole-lite and @anthropic-ai/sdk as shared packages, but they are bundled
+
+## 1.0.8
+
+### Added
+
+- `publicRateLimit` on `ctx.http.router()`, for a plugin whose public routes serve a proxied page
+
+## 1.0.7
+
+### Fixed
+
+- A migration file, or a part of one, holding only comments made core fail to start the plugin
+
 ## 1.0.6

+
+### Workers and WebAssembly
+
+Heavy work (decoding, encoding, parsing) belongs in a worker thread so it never blocks the server. Name
+each worker entry in `package.json`:
+
+```json
+"termix": { "workers": { "engine": "src/backend/engine/worker.ts" } }
+```
+
+`build` bundles it alone into `dist/workers/engine.js`; start it with
+`new Worker(new URL("./workers/engine.js", import.meta.url))`. A worker bundles everything it imports and
+can't use the shared packages above, so it must not import `@termix-ssh/plugin-sdk`. Talk to it with
+`postMessage`.
+
+Importing a `.wasm`, `.ttf` or `.otf` file gives its bytes as a `Uint8Array`, in `build` and in tests, so a module ships
+inside the bundle with no file to find. Compile it once on the main thread with `new WebAssembly.Module`
+and post that to each worker. Add `declare module "*.wasm" { const bytes: Uint8Array; export default bytes; }`
+to a `.d.ts` in the plugin.
