 # 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

 - Regional browser languages like `es-MX`, `pt` or `zh-HK` showed English instead of the closest translation

 - 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

-- 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
