Versioning

Versioning#

Philosophy#

SImMER generally follows semantic versioning guidelines. In brief, this means that our version numbers follow a AA.BB.CC convenion, with AA incrementing when a large, backward-incompatible changes are introduced to the code base; BB incrementing when backward-compatible functionality is added to a code; and CC incrementing whenever backward-compatible bugs are fixed. For example:

  • If a user input of square root scaling resulted in quadratic scaling, fixing this would result in CC increasing

  • If new plotting arguments are added to the plotting schema, `BB would increase

  • If Instruments were deprecated and a new class Telescopes were used in its stead, AA would increase

Additionally, suffixes (e.g. “-beta” or “-dev”) may be added to the release tag, signifying the degree to which developers are confident in production-ready (i.e., bug-free) code.

In practice#

This only applies to developers with write access to the code base. All that needs to be done is:

  1. Adjust the version specified in src/simmer/__init__.py. This will automatically update docs and setup.py configurations.

  2. Update the GitHub release version to match the version specified in Step 1. This will automatically publish the build on PyPI.

  3. Wait for the autotick bot on the SImMER feedstock repository to make a PR updating the version number. Then, wait for all the tests to pass.

  4. Make any neessary dependency changes to the corresponding recipe, then merge the PR. Note: Don’t add [skip ci] to the merge commit in the feedstock repository! This suffix will skip all continuous integration run in that repository, not just the SImMER tests on Azure. Therefore, the newest version won’t be available to install on conda.
