LArSoft release naming and retention policy

When breaking changes are introduced in the code, they are usually documented more extensively in the Breaking Changes page.
Consider taking a look at it on each update, since the breakage could be subtler than just a compilation error.
See What to do when there is a new release

See Supported Platforms for a list of supported platforms.

Release versions in bold font will be preserved according to the production release retention policy.
