MsQuic releases and support
MsQuic follows semantic versioning.
Releases
MsQuic releases are supported for a minimum of 18 months after release, and may be supported longer. A new release is generally created every 6 months to a year.
End of support refers to the date when Microsoft no longer provides fixes, updates, or online technical assistance for your product. As this date nears, make sure to upgrade to a supported version.

MsQuic Branches
MsQuic has two main types of branches main and release defined as:
- main - Main is the primary development branch, and receives security and bug fixes just the same as the release branches. However, the main branch is where active development happens and it may experience breaking changes as we develop new features.
- release/X.Y - Release branches only receive security and bug fixes, and are considered stable.
