This METplus Release Guide provides detailed instructions for METplus developers for creating software releases for the METplus component repositories. This Release Guide is intended for developers creating releases and is not intended for users of the software.
Stages of the METplus Release Cycle
Beta releases are a pre-release of the software to give a larger group of users the opportunity to test the recently incorporated new features, enhancements, and bug fixes. Beta releases allow for continued development and bug fixes before an official release. There are many possible configurations of hardware and software that exist and installation of beta releases allow for testing of potential conflicts.
Release Candidate (rc)
A release candidate is a version of the software that is nearly ready for official release but may still have a few bugs. At this stage, all product features have been designed, coded, and tested through one or more beta cycles with no known bugs. It is code complete, meaning that no entirely new source code will be added to this release. There may still be source code changes to fix bugs, changes to documentation, and changes to test cases or utilities.
An official release is a stable release and is basically the release candidate, which has passed all tests. It is the version of the code that has been tested as thoroughly as possible and is reliable enough to be used in production.
A bugfix release introduces no new features, but fixes bugs in previous official releases and targets the most critical bugs affecting users.
Instructions are provided for three types of software releases:
Official Release (e.g. vX.Y.Z) from the develop branch (becomes the new main_vX.Y branch)
Bugfix Release (e.g. vX.Y.Z) from the corresponding main_vX.Y branch
Development Release (e.g. vX.Y.Z-betaN or vX.Y.Z-rcN) from the develop branch
The instructions that are common to all components are documented only once and then included in the release steps for all components. However some instructions are specific to individual repositories and documented separately.
Release instructions for each of the METplus components are described in the following chapters.
