This is done via addition of the `com.termux.RUN_COMMAND_SESSION_CREATE_MODE` extra, which currently supports two values.
- `always` to always create a new session every time.
- `no-session-with-name` to create a new session only if no existing session exits with the same terminal session name.
The terminal session name will equal executable basename by default and dashes `-` in the basename will no longer be replaced with spaces when session name as done previously. The `com.termux.RUN_COMMAND_SESSION_NAME` extra can be used to set custom session name.
Usage:
You can use this with `Termux:Tasker` or `Termux:Widget`.
For example for `Termux:Widget`
- Create a wrapper script at `~/.shortcuts/tasks/my-script.sh` with following contents under `tasks` directory so that it runs in background app shell instead of a terminal session. Do not use terminal session runner for wrapper script, since it will open two sessions everytime otherwise, first for wrapper script, then for actual target executable. There would also be conflicts if both wrapper script and target executable have the same basename and it would be incorrectly assumed that session is already running.
- Replace the `bash` executable with actual target executable that you want to run in the terminal session if its not already running.
- Optionally set custom session name. By default it will set to executable basename and not the wrapper script name. To set it to wrapper script name, you can pass `$(basename "$0")`.
- Launch the wrapper script with widget. On first launch, a new terminal session should open but on subsequent launches, same terminal session should open.
Note that you can also pass `com.termux.RUN_COMMAND_SESSION_ACTION` to modify session action behaviour. Check https://github.com/termux/termux-app/wiki/RUN_COMMAND-Intent#run_command-intent-command-extras.

This starts the support for adb, root and other custom runners for shell commands. Previously only terminal and background tasks in app shells were supported.
`TERMUX_SERVICE.EXTRA_BACKGROUND` and `RUN_COMMAND_SERVICE.EXTRA_BACKGROUND` extras have been deprecated and instead respective `EXTRA_RUNNER` extra keys should be used. Currently supported extra values are `terminal-session` and `app-shell`. In future, `adb-shell` and `root-shell` are planned to be supported as well.
