 # Changelog
 
+## 26.11.1
+
+### Added
+
+- Termix actions: plugins can declare what they do once, and it works from the API with permission checks, dry runs, run history and approvals
+- API keys can be limited to reading or running actions, when an admin makes them
+- A click on a host can open its host page, when a plugin offers one
+
+### Changed
+
+- Host status, import and export, and credential tools now start on for new installs
+- Sync now starts on in a new desktop app, so it can link to a server
+- The first run plugin picker leaves plugins you did not choose off instead of removing them
+
+### Fixed
+
+- The first run plugin picker no longer sets the default layout and themes to Remove. They always stay on
+- Alerts with no icon no longer squeeze their text to one word per line
+- Password fields with the show button are the same height as the other fields next to them
+- The Secure your account setup step no longer shows up empty when no passkey or authenticator plugin is on
+
+## 26.11.0
+
+### Fixed
+
+- Saving the database no longer holds up the whole server while it encrypts and writes. A big database is also saved less often by background writes, which fixes slow requests and dropped connections
+- The macOS menu bar icon shows the logo instead of an empty shape on multi-architecture builds
+- Disabled plugins no longer show update or review buttons, and no longer count as pending updates
+- One slow request, like a plugin waiting on an SSH host, no longer shows Server connection lost. The app now checks the server first
+- Canceled requests no longer show Server connection lost
+- The macOS Window menu has an item to reopen the main window after it is closed
+- Hosts with both an SSH key and a password can log in to servers set to AuthenticationMethods publickey,password
+
 ## 26.10.6
 
 ### Added
 
 - The mobile app can sign in through your browser with any login method, including passkeys and security keys
+- Plugins can say how they show in the mobile app
+- The plugin list tells the mobile app which plugin API each plugin needs, so the app can say when it or a plugin needs an update
+- Hosts can have a color and an icon, which sync to the desktop and mobile apps
+- A sidebar setting to turn off alternating row colors
+- TERMIX_NGINX_TEMPLATE, TERMIX_NGINX_CONF, TERMIX_NGINX_PID and TERMIX_APP_DIR let an install outside Docker, like the Proxmox LXC script, switch nginx to HTTPS when a certificate is added
+- Removing a user or role from a shared folder can also remove their access from every host in the folder and its subfolders
+- A personal login set once on a folder is used for every host shared with you in it and its subfolders, unless a host has its own
+
+### Changed
+
+- body-parser is updated to 2.4.0 for a security fix
+
+### Fixed
+
+- The log line for a rejected proxy login now shows the source address, so you can add it to TRUSTED_PROXY_AUTH_TRUSTED_PROXIES
+- Deleting your own account now removes all of its data, like an admin delete does, instead of leaving some behind
+- An SSH key with a passphrase is unlocked once and kept unlocked in memory for a short time, so connecting to many hosts with it no longer freezes the server for minutes
+- A change pushed from one linked desktop or phone now reaches your other linked devices right away, instead of on their next check a few minutes later
+- The macOS menu bar icon shows the Termix logo instead of an empty square
+- Cmd+1 (Alt+1 on Windows and Linux) and the other number shortcuts pick the open tabs as numbered in the tab bar, not the home tab
+- A plugin the app no longer ships and could not download (for example on a locked down network) shows as failed with the reason on the Plugins tab, instead of as installed
+- The desktop app no longer shows This layout could not be shown when the layout is asked for before its plugin has finished starting; it tries again
+- On the desktop, a plugin installed from the registry that uses core's packages through require (like ACME SSL and axios) starts instead of failing with Cannot find module
+- Adding a certificate on an install where Termix cannot manage nginx says what to set instead of only asking for a restart
+- A login someone shared with you works on a host shared with you, for personal SSH authentication and when the owner shares SSH authentication
+- Lists in plugins (like the AI Assets table) use their full width on narrow screens, keep cells under the right header and no longer overlap rows
+- Installing an official plugin from a file works offline: pick the .tmxplug and its .sig from the release together and it installs as official, so plugins like Fleets no longer stop with migration refused. It can also fill in a plugin that was on but could not be downloaded

+- `contributes.mobile` in the manifest says how a plugin shows in the Termix mobile app: `webview`, `native` or `none`, with an optional mobile bundle, screen sizes, views and a note
+- `termix-plugin build` bundles `src/mobile` into the `contributes.mobile.entry` file, and `validate` checks that it exists
+- `@termix-ssh/plugin-sdk/frame-host` runs one plugin view outside the shell, with core's bridge, registries and CSS, so the mobile app can show `webview` plugins
+- SSH transport providers get the host's owner, sync id, connection origin and local only flag in `claims` and `open`, and core's SSH relay takes a `syncId` instead of a host id
+- `ctx.sync.host.entities.idsOf` maps sync ids to the local ids of the user's own rows of one type
+- Rail items take `useStatus` for a small ok, warning or error dot on the icon
+- `shell.editHost(hostId)` opens the editor of a saved host
+- A sync entity can be read only with `load`, `write` and `erase`, so a plugin can sync rows a user does not own, like a shared library, down to linked desktops
+- `getFolderAuthOverride` and `setFolderAuthOverride` in `@termix-ssh/plugin-sdk/ui` read and set a user's own login for the shared hosts in a folder
+
+### Fixed
+
+- `@termix-ssh/plugin-sdk/ui` is built in production mode, so outside Termix it no longer sends requests to the Vite dev server path
+- `execCommand` buffers output and decodes it once as strict UTF-8 with a GBK fallback, exposed as `decodeCommandOutput`, so messages from a Windows host on a legacy codepage are readable instead of � characters

+
+`build` makes `entry` from `src/mobile/index.tsx`, and it shares `frontend.css`.
+
+How a `webview` plugin runs in the app:
+
+- Only your plugin loads, with the same app object, SDK hooks and `/ui` kit as the web app. Each view opens
+  on its own screen: a tab with `host-context-menu` in `openFrom` opens from a host, the rest from the app's
+  plugin list.
+- Every request and socket goes through the app, which adds the login, proxy headers and client
+  certificate. The app only lets through your own `/plugin-api`, `/plugin-ws` and `/plugin-assets`, your
+  settings and a short list of core reads (hosts, folders, permissions, current user, version, health,
+  activity). Other core routes answer 403, so call your own backend instead.
+- Images load straight from the server, without proxy headers or a client certificate.
+- Nothing in `localStorage` survives closing the view. Keep preferences in settings.
+- Other plugins' views, extensions and components are not there, and neither is the shell (`useShell()`
+  is null). `/ui` names newer than the app's copy of the SDK make the view say it needs a newer app.
+- The app checks your `engine.api` against the plugin API of its own copy of the SDK. When the app's API
+  is too old for the range, it asks the user to update the app instead of opening the view. When the range
+  is for an older API major, it asks to update the plugin. Ask only for the API you use.
+- Turning a plugin off on the server hides it in the app the next time the app checks: when it comes back
+  to the front, when the list is pulled down, or when any request answers 503 with your `pluginId`.
+
+Termix 26.10.5 and older refuse any manifest with `mobile`, so a plugin that declares it needs
+`"engine": { "termix": ">=26.10.6", "api": "^1.13" }`.

+### Operations
+
+Declare what your plugin can do in `contributes.operations`, and it shows up in Automations, Fleets, the
+assistant, the CLI, the phone app and the command palette with no other wiring. It also gets per host results,
+dry runs, run history, approvals and drift checks.
+
+```json
+"capabilities": ["operations:provide"],
+"engine": { "termix": ">=26.11.1-0", "api": "^1.13" },
+"contributes": {
+  "operations": {
+    "actions": [{
+      "id": "demo.restart",
+      "titleKey": "ops.restart.title",
+      "scope": "host",
+      "inputs": [{ "key": "name", "type": "string", "labelKey": "ops.restart.name", "required": true }],
+      "risk": "change",
+      "permission": "use",
+      "hostAccess": "edit",
+      "dryRun": "describe"
+    }]
+  }
+}
+```
+
+```ts
+ctx.operations.register("demo.restart", {
+  describe: (input) => `Would restart ${input.name}`,
+  run: async (input, { hostId, signal, log }) => {
+    return { summary: `Restarted ${input.name}`, changed: true };
+  },
+});
+```
+
+- Actions: `scope` is `host`, `resource` or `server`. `risk` is `read`, `change` or `destructive`. Host actions declare
+  `hostAccess`. Use `edit` for changes unless people with `connect` already do this today. A destructive action
+  must use `edit` or `manage` and needs a confirm.
+- Inputs use the settings field types, plus `required`, `pattern`, `optionsFrom` (a read action fills the choices)
+  and type `resource`. Keys you did not declare are refused before your handler runs. `secret` values reach the handler
+  but are never stored or shown. Mark private outputs `sensitive`.
+- `dryRun`: `native` calls `run` with `dryRun: true` and nothing may change. `describe` calls `describe` instead.
+- `check` names a read action that proves the result, used for drift. `undo` names the reverse action, and `run` returns
+  `undoInput`. `idempotent` lets a rollout retry it. `exclusive` allows one at a time per host. `when` limits it to
+  hosts by setting or OS.
+- `surfaces`: the assistant and MCP are off until you set them true. Only do that for actions safe for a model to
+  ask for. The rest are on unless you set them false.
+- Resources describe a kind of thing, such as a container: a read action on one host returns `{ rows }` as `data`, and
+  core draws the All hosts table and host page section. Attach actions with `scope: "resource"`.
+- Signals are status tiles: a read action returns `{ value, status, label }` as `data`, with status `ok`, `warn`, `fail` or
+  `unknown`. `fix` names the action offered when it is not ok. Keep these reads cheap, they run for every host.
+- Events: declare them, then call `ctx.operations.emit(id, payload, { hostId })`.
+- Handlers must watch `signal` and stop when it fires. Throw on failure; a failed run never counts against your
+  plugin's error budget. Throw an error with `code = "NEEDS_INTERACTION"` when a host needs a person to sign in first.
+- Handlers have no request and no session. Take what you need from the input and `hostId`.
+- Keep your REST routes. Inside one, call `ctx.operations.run(id, { hostId, input })` so a button press goes through
+  the same checks and lands in the same history.
+- To run another plugin's action, add `operations:invoke`, list it in `operations.invokes` and call
+  `ctx.operations.invoke(id, { hostId, input, via: "automation" })`. It acts as the current user and rules still apply.
+- `risk` is your plugin's claim. Plugins run in-process, so this is not a sandbox. Actions from plugins not signed as
+  official count as `change` when rules decide what needs a person, and stay off the assistant and MCP until an admin
+  allows them.
+- Set `engine.termix` to at least `>=26.11.1-0`. Keep `engine.api` as it was unless you import something new from
+  `/ui`, or the phone app will ask people to update to see your plugin.
