This page gives an overview of upstream projects. If you miss information or find mistakes, please edit.
The GNU Binutils are a collection of binary tools (GNU linker, GNU assembler, many other excellent tools such as gprof).
Rule of thumb: Binutils (GNU linker, GNU assembler, tons of other excellent tools) releases twice per year (mid July and mid January).
RV32G and RV64G are mostly implemented. However, there is still some optimization potential.
The GNU Compiler Collection (GCC) includes front ends for C, C , Objective-C, Fortran, Ada, Go, and D, as well as libraries for these languages (e.g. libstdc).
Rule of thumb: GCC closes the merge window for the next release in mid-November (once per year).
After stage 3 has started, new functionality may not be introduced.

RV32G and RV64G are mostly implemented. However, there is still some optimization potential.
GDB is the GNU Project debugger.
GDB major releases are approximately annually. There are typically one or two minor releases each year. This is the typical schedule:
At the time of writing the most recent release was 10.1, released on 2020-10-24. Dates for branching (and hence release) of GDB 11 have yet to be announced.
Debugging works on top of PTRACE syscalls. HW-Breakpoint or HW-Watchpoint support is missing.
Glibc is the GNU C library.
Rule of thumb: Glibc releases twice per year (February and August).
Previous releases:
RV32 and RV64 are supported. Still, there is optimization and completeness potential.
The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.
The upstream release page can be found here.
RV32G and RV64G are mostly implemented. However, there is still some optimization potential.
Newlib is a C standard library implementation intended for use on embedded systems.
Rule of thumb: Newlib releases once per year.
Last releases:
RV32 and RV64 are supported. Still, there is optimization and completeness potential.
