# Release Notes

## Minimum version of GLIBC required

The minimum version of GLIBC required is now 2.31.
This version can be found in Ubuntu 20.04 and later, RHEL 9.0 and later and other distros as well.
CDT's native components will likely work with older versions of glibc too, assuming they provide the required APIs for Eclipse CDT.

# Managed Build

## Other objects for GNU archive files

The managed build system now provides an option to specify other object files to be included when building GNU archive files:

The new option applies to static library projects using a _Cross GCC_, _Cygwin GCC_, _Linux GCC_ or _MinGW GCC_ toolchain.
