# Koshi 0.2.0 — Changelog (/docs/v0.2/changelog)



## v0.2.0 [#v020]

* Sessions run in their own process and keep running after the terminal leaves.
* `koshi attach` joins a running session; without a name it lists the running
  ones to pick from.
* `koshi detach` leaves a session without ending it; `--all` detaches every
  terminal of one session.
* `koshi --headless` starts a session with no terminal attached and prints its
  id.
* `koshi attach <session>` typed inside a pane moves that terminal to another
  session.
* Several terminals can view one session at once, each with its own focus and
  view.
* A terminal that missed an event resyncs instead of drawing a stale view.
* The quit shortcut leaves the session running instead of ending it.
* `auto-close-session` ends a session once its last terminal leaves.
* Each terminal reads its own theme, keybindings, and view settings from its
  own files.
* Sessions and tabs accept their printed id anywhere their name is accepted,
  and an id is never re-read as a name.
* `koshi debug dump-state` and `koshi debug dump-layout` print running state and
  solved layouts.
* A panic writes `crash-<timestamp>.txt` to the data directory after restoring
  the terminal.
* Terminal reset and custom tab stops.
* A koshi that cannot speak another koshi's protocol version refuses and names
  both version ranges.
* The session server starts with no console window on Windows.
* Dragging a pane border moves it the whole drag distance in one step instead
  of one cell at a time.
* The shortcut hint bar updates without waiting for the next frame.
* A stop request that fails skips the wait and ends the process at once.
* `allow-beta-features` runs features still marked beta; this release marks
  none.
* Smaller cell storage, cheaper mouse movement, and lower scrollback memory.

* Input aimed at an open shortcut stays in koshi until that shortcut completes
  or is cancelled.
* Pane input reaches only panes visible to the issuing client.
* New panes inherit the issuing terminal's working directory when no directory
  is given.
* Config files require an explicit schema version.

  output.
