 # Changelog
 
-## [2.0.0-alpha.1] 2022-06-17
+## [2.0.0-alpha.2] 2022-07-07
 
-### Removed
+### Added
+- `stg email format` wraps `git format-patch` and provides a mechanism
+  to generate patch emails and optional cover letter in mbox format.
+- `stg email send` wraps `git send-email` and allows sending patch
+  emails, either from files generated by `stg email format` or by
+  specifying patches directly.
+
+### Changed
+- Bash completions for shell aliases now fallback to filename
+  completions (#191).
+- Help options listings now ensure --color and --help are shown last.
+- Various zsh completion improvments:
+  - Add descriptions for --color values
+  - Complete -O/--diff-opts values (using `git diff-tree --git-completion-helper`)
+  - Comprehend `stg -C <dir>` options
+  - Improved/corrected alias expansion
+  - Improved error messages when completion is attempted outside git
+    repo and/or StGit-initialized branch
+  - Patch name completions now look and feel like output from `stg
+    series`
+  - Complete patch range syntax ('patch0..patchN') for all relevant
+    commands
+  - Completion for `stg squash` no longer allows duplicate patch name
+    arguments
+  - Removed completions for removed `stg mail` command
+  - Completion for `stg sink` no longer offers hidden patches
+  - Completion for `stg rename` comprehends second, new patch name
+    argument
+  - Completion for `stg diff --range` now works
+
+### Fixed
+- Compatibility with git versions prior to 2.35.0 is repaired by
+  avoiding using `git apply --allow-empty` (#192).
+- Fish completions for -O/--diff-opts are repaired

 - `stg spill` replaces `stg refresh --spill`.
 
 ### Changed
+- StGit aliases are now more like Git aliases. Normal aliases refer to
+  StGit subcommands, but aliases prefixed with '!' are shell aliases
+  that may run arbitrary commands. An example normal alias would be
+  `git config stgit.alias.list 'series --description --empty'`. An
+  example shell alias would be `git config stgit.alias.st '!git status
+  --short'`.
 - The `--ack` and `--review` options now optionally take a value. The
   `--ack-by` and `--review-by` options are deprecated.
 - Commands such as `stg goto`, `stg push`, and `stg pop` now require
