@@ -3,12 +3,12 @@ Release checklist
 - [ ] Check [latest documentation](https://python-zlib-ng.readthedocs.io/en/latest/) looks fine.
 - [ ] Create a release branch.
   - [ ] Change current development version in `CHANGELOG.rst` to stable version.
+- [ ] Check if the address sanitizer does not find any problems using `tox -e asan`
 - [ ] Merge the release branch into `main`.
 - [ ] Created an annotated tag with the stable version number. Include changes 
 from CHANGELOG.rst.
 - [ ] Push tag to remote. This triggers the wheel/sdist build on github CI.
 - [ ] merge `main` branch back into `develop`.
-- [ ] Add updated version number to develop. (`setup.py` and `src/zlib_ng/__init__.py`)
 - [ ] Build the new tag on readthedocs. Only build the last patch version of
 each minor version. So `1.1.1` and `1.2.0` but not `1.1.0`, `1.1.1` and `1.2.0`.
 - [ ] Create a new release on github.

+version 1.0.0
+-----------------
+The library has been running without issues as a dependency in quite a few
+projects and is now stable enough for the first major version.
+
++ Updated bundled zlib-ng to 2.2.5.
++ Python 3.14 is supported.
++ Python 3.8 and 3.9 are no longer supported.
++ Fix an issue where flushing using igzip_threaded caused a gzip end of stream
+  and started a new gzip stream. In essence creating a concatenated gzip
+  stream. Now it is in concordance with how single threaded gzip streams
+  are flushed using Z_SYNC_FLUSH.
++ Switched to setuptools-scm for building the package rather than versioningit.
++ Test files are added to the source distribution.
++ Fix an issue where some tests failed because they ignored PYTHONPATH.
+
 version 0.5.1

 + Fix a bug where flushing in threaded mode did not write the data to the
