## Supported Versions

Security updates are applied to the latest feature release (1.x) of the compiler, standard library, and build plugins.

A fix will be shipped with the next incremental (1.x.y) or bug fix release (1.x.yz).

All fixes are also applied to the master branch to be included in all upcoming releases.
