-> **Note:** Please do not file an issue to ask a general question about LAMMPS, its features, how to use specific commands, or how perform simulations or analysis in LAMMPS. Instead post your question to either the ['lammps-users' mailing list](https://lammps.sandia.gov/mail.html) or the [LAMMPS Material Science Discourse forum](https://matsci.org/lammps). You do not need to be subscribed to post to the list (but a mailing list subscription avoids having your post delayed until it is approved by a mailing list moderator).

 ### Discussing How To Use LAMMPS
 
 The LAMMPS mailing list is hosted at SourceForge. The mailing list began in 2005, and now includes tens of thousands of messages in thousands of threads. LAMMPS developers try to respond to posted questions in a timely manner, but there are no guarantees. Please consider that people live in different timezone and may not have time to answer e-mails outside of their work hours.

 ### Reporting Bugs
 
-While developers writing code for LAMMPS are careful to test their code, LAMMPS is such a large and complex software, that it is impossible to test for all combinations of features under all normal and not so normal circumstances. Thus bugs do happen, and if you suspect, that you have encountered one, please try to document it and report it as an [Issue](https://github.com/lammps/lammps/issues) on the LAMMPS GitHub project web page. However, before reporting a bug, you need to check whether this is something that may have already been corrected. The [Latest Features and Bug Fixes in LAMMPS](https://lammps.sandia.gov/bug.html) web page lists all significant changes to LAMMPS over the years. It also tells you what the current latest development version of LAMMPS is, and you should test whether your issue still applies to that version.

 You can also attach small text files (please add the file name extension `.txt` or it will be rejected), images, or small compressed text files (using gzip, do not use RAR or 7-ZIP or similar tools that are uncommon outside of Windows machines). In many cases, bugs are best illustrated by providing a small input deck (do **not** attach your entire production input, but remove everything that is not required to reproduce the issue, and scale down your system size, that the resulting calculation runs fast and can be run on small desktop quickly).

 ### Pull Requests
 
 Pull requests are the **only** way that changes get made to the LAMMPS distribution.  So also the LAMMPS core developers will submit pull requests for their own changes and discuss them on GitHub.  Thus if you submit a pull request it will be treated in a similar fashion. When you submit a pull request you may opt to submit a "Draft" pull request.  That means your changes are visible and will be subject to testing, but reviewers will not be (auto-)assigned and comments will take into account that this is not complete. On the other hand, this is a perfect way to ask the LAMMPS developers for comments on non-obvious changes and get feedback and possible suggestions for improvements or recommendations about what to avoid.
-Immediately after the submission, the LAMMPS continuing integration server at ci.lammps.org will download your submitted branch and perform a number of tests: it will tests whether it compiles cleanly under various conditions, it will also do a check on whether your included documentation translates cleanly and run some unit tests and other checks. Whether these tests are successful or fail will be recorded.  If a test fails, please inspect the corresponding output on the CI server and take the necessary steps, if needed, so that the code can compile cleanly again.  The test will be re-run each time the pull request is updated with a push to the remote branch on GitHub.  If you are unsure about what you need to change, ask a question in the discussion area of the pull request.

If you are unsure about what you need to change, ask a question in the discussion area of the pull request.
 Next a LAMMPS core developer will self-assign and do an overall technical assessment of the submission.  If you submitted a draft pull request, this will not happen unless you mark it "ready for review".  If you are not yet invited as a LAMMPS collaborator, and your contribution seems significant, you may also receive an invitation for collaboration on the LAMMPS repository.  As part of the assessment, the pull request will be categorized with labels. There are two special labels: `needs_work` (indicates that work from the submitter of the pull request is needed) and `work_in_progress` (indicates, that the assigned LAMMPS developer will make changes, if not done by the contributor who made the submit). 
 You may also receive comments and suggestions on the overall submission or specific details and on occasion specific requests for changes as part of the review. If permitted, also additional changes may be pushed into your pull request branch or a pull request may be filed in your LAMMPS fork on GitHub to include those changes.
 The LAMMPS developer may then decide to assign the pull request to another developer (e.g. when that developer is more knowledgeable about the submitted feature or enhancement or has written the modified code). It may also happen, that additional developers are requested to provide a review and approve the changes. For submissions, that may change the general behavior of LAMMPS, or where a possibility of unwanted side effects exists, additional tests may be requested by the assigned developer.

+# LAMMPS Release Steps
+
+The following notes chronicle the current steps for preparing and publishing LAMMPS releases.  For
+definitions of LAMMPS versions and 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.  This is not a fixed rule, though, since
+external circumstances can cause delays in preparing a release, or pull requests that are desired to
+be merged for the release are not yet completed.
+
+### 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"
+- check release notes for merged new features and check if ..versionadded:: or ..versionchanged::
+  are missing and need to be added
+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.
+
+### Create release on GitHub
+
+When all pending pull requests for the release are merged and have cleared testing, the
+'next\_release' branch is merged into 'develop'.
+
+Check out 'develop' locally, pull the latest changes, merge them into 'release', apply a suitable
+release tag (for historical reasons the tag starts with "patch_" followed by the date, and finally
+push everything back to GitHub. Example:
+
+```
+git checkout develop
+git pull
+git checkout release
+git pull
+git merge --ff-only develop
+git tag -s -m "LAMMPS feature release 19 November 2024" patch_19Nov2024
+git push git@github.com:lammps/lammps.git --tags develop release
+```
+
+Go to https://github.com/lammps/lammps/releases and create a new (draft) release page or check the
+existing draft for any necessary changes from pull requests that were merged but are not listed.
+Then select the applied tag for the release in the "Choose a tag" dropdown list. Go to the bottom of
+the list and select the "Set as pre-release" checkbox.  The "Set as the latest release" button is
+reserved for stable releases and updates to them.
+
+If everything is in order, you can click on the "Publish release" button.  Otherwise, click on "Save
+draft" and finish pending tasks until you can return to edit the release page and publish it.
+
+### Update download website, prepare pre-compiled packages, update packages to GitHub
+
+Publishing the release on GitHub will trigger the Temple Jenkins cluster to update
+the https://docs.lammps.org/ website with the documentation for the new feature release
+and it will create a tarball for download (which contains the translated manual).
+
+Build a fully static LAMMPS installation using a musl-libc cross-compiler, install into a
+lammps-static folder, and create a tarball called lammps-linux-x86_64-19Nov2024.tar.gz (or using a
+corresponding date with a future release) from the lammps-static folder and upload it to GitHub
+with:
+
+```
+gh release upload patch_19Nov2024 ~/Downloads/lammps-linux-x86_64-19Nov2024.tar.gz
+```
+
+
+## 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
+
+

+LAMMPS and LAMMPS GUI universal binaries for macOS (arm64/x86_64)
+=================================================================
+
+This package provides universal binaries of LAMMPS and LAMMPS GUI that should
+run on macOS systems running running macOS version 11 (Big Sur) or newer.  Note
+the binaries are compiled without MPI support and contain a compatible subset
+of the available packages.
+
+The following individual commands are included:
+binary2txt lammps-gui lmp msi2lmp phana stl_bin2txt
+
+After copying the LAMMPS_GUI folder into your Applications folder, please follow
+these steps:
+
+1. Open the Terminal app
+
+2. Type the following command and press ENTER:
+
+   open ~/.zprofile
+
+   This will open a text editor for modifying the .zprofile file in your home
+   directory.
+
+3. Add the following lines to the end of the file, save it, and close the editor
+
+   LAMMPS_INSTALL_DIR=/Applications/LAMMPS_GUI.app/Contents
+   LAMMPS_POTENTIALS=${LAMMPS_INSTALL_DIR}/share/lammps/potentials
+   LAMMPS_BENCH_DIR=${LAMMPS_INSTALL_DIR}/share/lammps/bench
+   MSI2LMP_LIBRARY=${LAMMPS_INSTALL_DIR}/share/lammps/frc_files
+   PATH=${LAMMPS_INSTALL_DIR}/bin:$PATH
+   export LAMMPS_POTENTIALS LAMMPS_BENCH_DIR PATH
+
+4. In your existing terminal, type the following command make the settings active
+
+   source ~/.zprofile
+
+   Note, you don't have to type this in new terminals, since they will apply
+   the changes from .zprofile automatically.
+
+   Note: the above assumes you use the default shell (zsh) that comes with
+   MacOS. If you customized MacOS to use a different shell, you'll need to
+   modify that shell's init file (.cshrc, .bashrc, etc.) instead with
+   appropiate commands to modify the same environment variables.
+
+5. Try running LAMMPS (which might fail, see step 7)
+
+   lmp -in ${LAMMPS_BENCH_DIR}/in.lj
+
+6. Try running the LAMMPS GUI
+
+   lammps-gui ${LAMMPS_BENCH_DIR}/in.rhodo
+
+   Depending on the size and resolution of your screen, the fonts may be too
+   small to read. This can be adjusted by setting the environment variable
+   QT_FONT_DPI. The default value would be 72, so to increase the fonts by a
+   third, one can add to the .zprofile file the line
+
+   export QT_FONT_DPI=96
+
+   and reload as shown above.
+
+7. Give permission to execute the commands (lmp, lammps-gui, msi2lmp, binary2txt, phana, stl_bin2txt)
+
+   MacOS will likely block the initial run of the executables, since they were
+   downloaded from the internet and are missing a known signature from an
+   identified developer. Go to "Settings" and search for "Security settings".
+   It should display a message that an executable like "lmp" was blocked. Press
+   "Open anyway", which might prompt you for your admin credentials. Afterwards
+   "lmp" and the other executables should work as expected.
