Releases and Versioning Scheme

The versioning scheme for the ImFusion SDK is mostly based on the Semantic Versioning standard with some small adjustments. Version numbers use the format <major>.<minor>.<patch>[-<suffix>].

• The <major> version is incremented when fundamental features have been changed and/or other large API-breaking changes are implemented.
• The <minor> version is incremented regularly based on our release cycle. New minor versions can include both new features and changes to existing functionality. We try to implement changes in a backward-compatible fashion, however in contrast to classic SemVer we do not guarantee this. There may be small adjustments/migrations necessary between minor versions.
• The <patch> version is incremented for bugfix/hotfix releases. They do not break API and should not add new functionality.
• The <suffix> part is optional and similar to the pre-release label of SemVer. If present it encodes additional metadata about the particular build
  • A dev suffix indicates a rolling-release build that was built from latest master at the time.
  • A rc suffix indicates a release candidate for an upcoming official general release.
  • Other suffixes can be used to denote releases that include customer/project-specific specializations.

We aim to publish a new general minor release at least twice a year.

Platform Support Lifecycle

For general releases we use the following scheme regarting support of OS and compiler versions:

• Windows / MSVC: 6 months after a next-next Visual Studio version has been released.
  Recently, Microsoft announced a restructuring of their release cadence and support lifecycle. As a result we might switch to a "6 months after end of official LTS support" scheme for MSVC in the future.
• Ubuntu / GCC: only LTS versions, support ends 6 months after end of official support by Canonical.
• macOS / Apple Clang: support for macOS is limited generally and some features (e.g. advanced rendering capabilities) are not available on this platform due to hardware/driver limitations. Our platform support ends 6 months after end of official support by Apple.
