## [0.15] 2009-10-24

### Removed
- The commands "stg add", "stg rm", "stg cp", and "stg resolved" were
  removed, since there are corresponding Git equivalents.

### Added
- New core infrastructure for repository operations, including:
  - Infinite undo/redo operations and corresponding commands.
  - Automatic rollback of changes following a failed operation (using
    transactions)---this ensures that StGit commands either succeed or
    do nothing. Previously, every commands had its own ad hoc
    implementation of this.
- Some commands were added, including
  - `stg squash`, for combining two or more patches into one.
  - `stg publish`, for maintaining merge-friendly branches (which are
    not rebased).

    in the series.
- The `stg import` and `stg fold` commands support the `-p N` option for
  stripping leading slashes from diff paths.
- The `stg import` and `stg fold` commands support the `--reject` option
  for leaving rejected hunks in corresponding `*.rej` files.
- New patch identification syntax: `<branch>:<patch>` (see documentation
  for the "stg id" command).
- Autosigning of imported patches when `sign.autosign` configuration
  option is set.
- A powerful Emacs mode for StGit was added to the "contrib" directory.
  It displays the patch stack in an Emacs buffer, and can handle all
  common StGit tasks.
- Man pages and an improved tutorial.

### Changed
- Improved bash tab-completion, automatically generated from the stg
  command definitions.
