+Changes since 0.19:
+===================
 
-- Python 3 support. StGit supports Python 2.6, 2.7, 3.3, 3.4, 3.5, 3.6,
-  and 3.7. PyPy interpreters are also supported.
+Features:
+- `stg patches -d` can now output colored diffs.
+- `stg publish --overwrite` allows branch to be overwritten instead of creating
+  new commits.
+- `stg log --clear` deletes the stack's log history. Use with caution.
+- Fish shell completions for stg.
+- Zsh completions for stg.
+- Branch protection metadata now captured in config instead of
+  .git/patches/<branch>protect file. This updates stgit's metadata format from
+  v2 to v3.
+- `stg mail --domain` option overrides the host's domain in the message ID.
 
-- Submodules are now ignored when checking if working tree is clean. Submodules
-  are also not included by default when refreshing a patch.
+Bug fixes:
+- `stg show` detects conflicting --applied and --unapplied options.
+- `stg show --stat` now shows commit headers.
+- `stg patches --diff` now shows proper diff instead of `b'...'` repr of diff.
+- `stg diff --range` detects some invalid values (e.g. `-r ..`).
+- `stg diff` no longer shows binary diffs by default. Use `-O--binary` or add
+  `--binary` to stgit.diff-opts in config.
+- Date parsing is now more portable, only use platform specific `date` as last
+  parsing option. Affects, e.g., `stg refresh --authdate`.
+- Repaired seach path for templates to avoid looking in Python site-packages
+  directory.
+- Ensure stdout and stderr are flushed. Rarely affected `stg diff`.
+- `stg repair` will now fail if extra command line arguments are provided.
+- Bash completions are now generated in a reproducible manner.
+- `stg edit --diff` on an empty patch no longer crashes.
+- Diagnostic output is now routed to stderr instead of stdout. Diagnostic output
+  is also now sent to stderr unconditionally, i.e. no more isatty() test (#35).
+- `stg pick` no longer fails when picked commit has empty message (#39).
+- `stg rebase` no longer crashes when there are conflicts (#34).
+- `stg pick` no longer crashes if --name is not provided when picking a regular
+  commit object.
 
-- Config booleans are now parsed similarly to git-config.
-
-- contrib/stgit.el is now licenced with GPLv2.
-
-- Repair handling of emails with utf-8 bodies containing latin-1 characters.
-  Also correctly decode email headers containing quoted encoded words.
-
-- StGit's version is now correct/available the release archive.
-
-- Add continuous integration (travis-ci) and code coverage (coveralls) support.
-
-- Many new test cases were added.
+Code quality:
+- Converted to "new" lib infrastructure: show, patches, diff, pick, pull,
+  rebase, and fold.
+- Improved test coverage for: branch, diff, pick, sync,
+- New tests for: files, patches, fold, series
+- Portable use of iconv, sort, and sed in tests.
+- Linting using flake8 and isort.
+- All Python code now conforms to PEP-8.
+- Updated test infrastructure from git 2.20.
+- Parallel tests with coverage (`make -j4 coverage`) now works.
+- Documentation build is not included in code coverage.
+- Repaired log end messages when using STGIT_SUBPROCESS_LOG=debug.
+- Renamed "dunder" instance attributes to improve debugging.
+- Fail faster when patch name has slash ('/') (#24).
