-> **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). Most posts to the mailing list receive a response within less than 24 hours. Before posting to the mailing list, please read the [mailing list guidelines](https://lammps.sandia.gov/guidelines.html). Following those guidelines will help greatly to get a helpful response. Always mention which LAMMPS version you are using. The LAMMPS forum was recently created as part of a larger effort to build a materials science community and have discussions not just about using LAMMPS. Thus the forum may be also used for discussions that would be off-topic for the mailing list. Those will just have to be posted to a more general category.

 ### 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.
-You can post to list by sending your email to lammps-users at lists.sourceforge.net (no subscription required), but before posting, please read the [mailing list guidelines](https://lammps.sandia.gov/guidelines.html) to maximize your chances to receive a helpful response.

 Anyone can browse/search previous questions/answers in the archives. You do not have to subscribe to the list to post questions, receive answers (to your questions), or browse/search the archives. You **do** need to subscribe to the list if you want emails for **all** the posts (as individual messages or in digest form), or to answer questions yourself. Feel free to sign up and help us out! Answering questions from fellow LAMMPS users is a great way to pay back the community for providing you a useful tool for free, and to pass on the advice you have received yourself to others. It improves your karma and helps you understand your own research better.

 ### 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.

 When you click on the green "New Issue" button, you will be provided with a text field, where you can enter your message. That text field with contain a template with several headlines and some descriptions. Keep the headlines that are relevant to your reported potential bug and replace the descriptions with the information as suggested by the descriptions.
 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.

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.
 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.

 # Version Updates

+LAMMPS follows a continuous release development model.  We aim to keep
+the development version (`develop` branch) always fully functional and
+employ a variety of automatic testing procedures to detect failures of
+existing functionality from adding or modifying features.  Most of those
+tests are run on pull requests and must be passed *before* merging to
+the `develop` branch.  The `develop` branch is protected, so all changes
+*must* be submitted as a pull request and thus cannot avoid the
+automated tests.
+
+Additional tests are run *after* merging.  Before releases are made
+*all* tests must have cleared.  Then a release tag is applied and the
+`release` branch is fast-forwarded to that tag.  This is referred to to
+as a "feature release".  Bug fixes and updates are applied first to the
+`develop` branch.  Later, they appear in the `release` branch when the
+next patch release occurs.  For stable releases, backported bug fixes
+and infrastructure updates are first applied to the `maintenance` branch
+and then merged to `stable` and published as "updates".  For a new
+stable release the `stable` branch is updated to the corresponding state
+of the `release` branch and a new stable tag is applied in addition to
+the release tag.

+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.
