 # 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
+
 ## 26.10.1

 ### Added
@@ -13,13 +48,23 @@

 - Every language is now fully translated, in Termix and in every plugin, and stays up to date with each release
 - Languages with more than two plural forms, like Russian, Polish and Arabic, now use the right one
+- The Plugins tab shows how many times each plugin was downloaded, in a Downloads column
+- Plugins, Browse hides plugins you already have. Turn on Show installed to see them

 ### Fixed

 - Regional browser languages like `es-MX`, `pt` or `zh-HK` showed English instead of the closest translation
 - Counts like "1 keys" or "Moved 1 host(s)" now use the singular
- Plugin updates synced to the desktop app failed to start with "Cannot find package"
+- Plugin updates on the desktop app, synced or installed from the Plugins tab, failed to start with "Cannot find package"
 - The desktop app showed plugins that only run on the server as not running and out of date
+- Keep the terminal WebSocket open past nginx's 60s default
+- Plugin download counts now show in the Plugins tab without waiting for the background check
+- Clicking into a saved password, key passphrase or sudo password field and saving without typing erased it, which stopped sudo autofill
+- The desktop app now says when its data is from 2.8 or older and needs 2.9 first, instead of only saying the local server could not start
+- Client tunnels on the desktop app stopped with "Endpoint SSH connection closed" when a reverse proxy dropped their idle connection
+- Typing right after opening a host from the sidebar went to the host search instead of the new session
+- SSH config import failed on files that put a tab or `=` between a keyword and its value
+- App icons and the favicon have rounded corners again

 ## Overview

-Termix is a free, open source, self-hosted platform for managing your servers, built on plugins. The core is small. It keeps your hosts, credentials, users, sharing and sessions. Everything else, like the SSH terminal, remote desktop, file manager, Docker and metrics, is a plugin you can turn on, turn off or remove.

+What every install has, with or without plugins:

- **Hosts:** Save hosts in nested folders with tags and parent hosts, bulk edit, import and export, and use Quick Connect for one-off connections
- **Credentials:** Reuse saved passwords and keys across hosts, with host defaults you can set for the server, a user or a folder
- **Sharing and Roles:** Share hosts, credentials and folders with users or roles at four levels: connect, view, edit and manage
- **Accounts:** Local accounts, sessions you can see and revoke, trusted devices, API keys and an audit log
- **Security:** Passwords, keys and other secrets are encrypted per user, and the database can be encrypted on disk
- **Desktop Sync:** The desktop app runs on its own and can link to a Termix server to keep an offline copy of your account
- **Interface:** Tabs and split screen, a command palette (double tap left shift), rebindable shortcuts, themes, branding and around 30 languages
- **Databases:** SQLite by default, with PostgreSQL and MySQL supported too

 # 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.

ZacharyZcR	071711dafc	fix(sync): don't delete a local row when the server can't send its copy (#1650 ) * 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	2026-10-15 14:59:59 +08:00
ZacharyZcR	bc74fba3f5	fix(settings): leave user manage view when switching admin sections (#1649 ) The admin panel stays mounted across Settings pages, so an open user manage view kept replacing every other admin section until Back to users was clicked. Reset it whenever the selected section changes.	2026-10-15 14:55:00 +08:00
Ferdina Kusumah	694dc34b19	fix(i18n): keep Indonesian technical terms consistent (#1636 ) Use the English terms Indonesian users know for tunnel, snippet, deploy, file manager, remote desktop, jump host, passphrase, sidebar, toolbar, endpoint, browser and SSH agent, instead of mixing literal translations (terowongan, cuplikan, terapkan, bilah sisi, titik akhir, ...) with the English words. Match the split shortcuts to the split screen menu. Also fix the user data export description, which said secrets are encrypted while the English says they are decrypted.	2026-10-15 14:24:11 +08:00
ZacharyZcR	b3b08b4ff2	fix(sync): let a linked desktop enable mirrored plugins it does not trust on its own (#1632 ) * fix(sync): let a linked desktop enable mirrored plugins it does not trust on its own * fix(sync): switch off an untrusted mirrored plugin when the server updates it * fix: require local consent for mirrored plugin activation * docs: describe consent fields on the plugin state endpoint	2026-10-14 09:11:55 +08:00
ZacharyZcR	9b0af07607	fix: drop ssh_data.vault_profile_id so removing the vault plugin keeps hosts writable (#1633 ) The vault plugin renames vault_profiles to p_vault_profiles, and SQLite rewrites ssh_data's foreign key to follow it. Uninstalling the plugin then dropped p_vault_profiles and left ssh_data pointing at a missing table, so creating, cloning and deleting hosts failed with "no such table: main.p_vault_profiles". Postgres and MySQL refused the uninstall instead. The column was already copied into the vault plugin's host settings by 2.9, so retire it on every engine. The SQLite boot drop also repairs databases already in the broken state; MySQL drops the column's foreign key first.	2026-10-14 08:59:57 +08:00
ZacharyZcR	c044dbde87	fix(sync): send shared hosts with text columns in their stored form (#1631 ) resolveHostById turns forceKeyboardInteractive into a boolean, and the shared-host export passed it on as is. A desktop could not bind the boolean into the text column, so every shared host failed to apply.	2026-10-14 08:59:52 +08:00
ZacharyZcR	1396b3a70c	fix(desktop): find spawn-helper in universal macOS builds (#1630 ) The universal build ships app-arm64.asar and app-x64.asar instead of app.asar, so node-pty's helper path rewrite never pointed at the unpacked copy and every local terminal failed with posix_spawnp failed.	2026-10-14 08:59:46 +08:00
ZacharyZcR	4c9ee5923e	fix(sidebar): sort hosts by IP address numerically (#1629 )	2026-10-14 08:59:40 +08:00
ZacharyZcR	25e58a6425	fix(desktop): harden external editor and session cookie IPC (#1627 ) * fix(desktop): stop the renderer choosing the external editor binary or reading the session cookie open-external-editor now launches only the editor saved from a file dialog and refuses to hand executable file types to the OS opener. The unused get-session-cookie and wait-session-cookie channels, which returned the httpOnly jwt, are removed. * fix: validate setting keys before editor authorization	2026-10-14 08:22:15 +08:00
ZacharyZcR	7d13b2a9fe	fix: don't auto-enable synced plugins signed only by a server-sent key (#1623 ) * fix: don't auto-enable synced plugins signed only by a server-sent key Registry keys a linked server sends still let its plugins load on the desktop, but no longer count as a signer for switching them on or copying their grants. Keys the desktop added itself keep their trust. * fix: enforce local plugin trust across remote source labels * fix: require positive local trust for synced plugin keys	2026-10-14 08:20:09 +08:00
ZacharyZcR	e610aba0e5	fix: enforce unique usernames (#1628 ) * fix: enforce unique usernames Registration checked for a taken name, hashed the password, then inserted, with nothing in the schema enforcing uniqueness. Concurrent sign-ups could create two accounts with one name, after which login, password reset, proxy login and admin lookups by username picked between them arbitrarily. Add a unique index on users.username for every dialect. Existing duplicates are renamed (later rows get a -<id> suffix, the oldest keeps the name) rather than deleted. Registration and admin user creation now return the same 409 when the insert loses the race. * fix: avoid username collisions during migration	2026-10-14 08:17:47 +08:00
ZacharyZcR	3941dd4ecc	fix: keep foreign keys on during user data import (#1626 ) Import credentials before hosts and remap the file's credential ids to the ones created here, so hosts and protocol logins no longer point at another server's ids. With rows written in dependency order, the import no longer turns off SQLite foreign keys on the shared connection. The uploaded file is now removed on every exit path.	2026-10-14 08:13:04 +08:00
ZacharyZcR	872e5eba73	fix: check trusted proxy login against nginx's peer, not nginx (#1625 ) The backend only sees the bundled nginx on loopback, so the allowlist could only work by trusting 127.0.0.1, which let any client that reached nginx log in as anyone by sending the identity headers. nginx now passes its own TCP peer (before real_ip rewriting) in X-Termix-Proxy-Peer, and loopback connections are judged by that address instead.	2026-10-14 08:12:58 +08:00
ZacharyZcR	8c3f816407	fix: only trust the server's origin in the desktop login frame (#1624 ) The desktop sign-in iframe accepted AUTH_SUCCESS and system browser requests from whatever page it had navigated to, and posted replies (including 2FA temp tokens) to any origin. Messages must now come from the server's origin and replies are posted to it. The web UI also treated any framing page as the desktop app and posted the JWT to it. It now also requires the Termix-Desktop user agent.	2026-10-14 08:12:53 +08:00
ZacharyZcR	13f7aa95a3	fix(plugins): read artifact manifest with the same tar parser as the unpack (#1622 ) The consent check read the first manifest.json with a hand-written tar reader, while the unpack keeps the last one and also follows pax and long-name headers. An archive with two manifests could pass the check with one capability list and get granted another. Read the manifest with node-tar, count only plain files, and refuse archives that hold more than one manifest.json.	2026-10-14 08:12:47 +08:00
ZacharyZcR	8e5a50623c	fix(electron): validate external login URL scheme and callback port (#1621 )	2026-10-14 08:12:42 +08:00
ZacharyZcR	d791e52d82	fix: stop auto-accepting changed jump host keys (#1620 ) A jump hop whose key no longer matched the pinned fingerprint was silently accepted and the pin overwritten. Background status probes reconnect to jump hosts every cycle, so a MITM on that hop got the credentials with no user interaction. Changed jump host keys now go through the same path as any other host: prompt when there is a terminal socket, otherwise refuse.	2026-10-14 08:12:37 +08:00
