New features in GDB 8.3 include support for DWARF index caches and styling (colors) in the CLI and TUI. Source code styling is also available via the new SOURCE_HIGHLIGHT option (enabled by default). GDB 8.3 also adds support for FreeBSD/riscv64. In addition, kgdb has been updated for changes in 8.3 along with support for FreeBSD/riscv64 kernels. The libc++ helpers have been updated to a newer version which adds support for std::list<> and std::forward_list<>. The helpers now also support Python 3. Finally, a few post-8.3 patches have been backported which add suport for TLS (Thread Local Storage) variables on FreeBSD amd64, i386, powerpc, and riscv architectures. Note that amd64 and i386 do not support examining TLS variables in core dumps currently. This support along with support for additional architectures require kernel changes and will be added in the future once the kernel has been updated.
