+# LAMMPS Release Steps
+
+The following notes chronicle the current steps for preparing and publishing LAMMPS releases.
+For definition of what LAMMPS versions and the different kinds of releases mean, please
+refer to [the corresponding section in the LAMMPS manual](https://docs.lammps.org/Manual_version.html).
+
+## LAMMPS Feature Release
+
+A LAMMPS feature release is currently prepared after about 500 to 750 commits to the
+'develop' branch or after a period of four weeks up to two months.
+
+### Preparing a 'next\_release' branch
+
+Create a 'next\_release' branch off 'develop' and make the following changes:
+- set the LAMMPS\_VERSION define to the planned release date in src/version.h in the format "D Mmm YYYY" or "DD Mmm YYYY"
+- remove the LAMMPS\_UPDATE define in src/version.h
+- update the release date in doc/lammps.1
+- update all TBD arguments for ..versionadded::, ..versionchanged:: ..deprecated:: to the
+  planned release date in the format "DMmmYYYY" or "DDMmmYYYY"
+
+Submit this pull request, rebase if needed. This is the last pull request merged for the release
+and should not contain any other changes. (Exceptions: this document, last minute trivial(!) changes).
+This PR shall not be merged before **all** pending tests have completed and cleared. If needed, a
+bugfix pull request should be created and merged to clear all tests.
+
+## LAMMPS Stable Release
+
+A LAMMPS stable release is prepared about once per year in the months July, August, or September.
+One (or two, if needed) feature releases before the stable release shall contain only bug fixes
+or minor feature updates in optional packages.  Also substantial changes to the core of the code
+shall be applied rather toward the beginning of a development cycle between two stable releases
+than toward the end.  The intention is to stablilize significant change to the core and have
+outside users and developers try them out during the development cycle; the sooner the changes
+are included, the better chances for spotting peripheral bugs and issues.
+
+### Prerequesites
+
+Before making a stable release all remaining backported bugfixes shall be released as a (final)
+stable update release (see below).
+
+A LAMMPS stable release process starts like a feature release (see above), only that this feature
+release is called a "Stable Release Candidate" and no assets are uploaded to GitHub.
+
+### Synchronize 'maintenance' branch with 'release'
+
+The state of the 'release' branch is then transferred to the 'maintenance' branch (which will
+have diverged significantly from 'release' due to the selectively backported bug fixes).
+
+### Fast-forward merge of 'maintenance' into 'stable' and apply tag
+
+At this point it should be possible to do a fast-forward merge of 'maintenance' to 'stable'
+and then apply the stable\_DMmmYYYY tag.
+
+### Push branches and tags
+
+
