   - Provide a non-trivial test of the newly-built toolchain(s) based on a real-world project.
   - Support cyclic monthly build of modern, evolving GCC releases.
   - Publish the build artifacts directly from the GHA Workflow-Run(s).
-  - TBD: Publish named releases instead of cyclic build and publishing directly from the GHA Workflow-Run(s), see also [issue 26](https://github.com/ckormanyos/avr-gcc-build/issues/26).

+## Distribution: Releases and Build Artifacts
+
+Using released or CI-built artifacts can be convenient when you
+do not actually want to nor need to manually build
+`avr-gcc` toolchain.
+
+Releases and build artifacts consisting of the
+fully-built `avr-gcc` toolchain are occasionally created
+and published for `x86_64-linux-gnu` (Linux) and
+`x86_64-w64-mingw32` (Windows). These can be readily found
+on the repo front page and in CI workflow-run download-areas
+for immediate client use. The releases are permanent, whereby
+the built artifacts are limited to three days after the
+Workflow-Run(s).
 
 ## Workflow-Run
 
@@ -34,21 +49,9 @@ Workflow:
   - GCC prerequisites including [GMP](https://gmplib.org), [MPFR](https://www.mpfr.org), [MPC](https://www.multiprecision.org), etc. are built on-the-fly in the Workflow-Run.
   - Build [`binutils`](https://www.gnu.org/software/binutils) and partially verify the build artifacts.
   - Then build `avr-gcc` and partially verify the build artifacts.
-  - Get a modern release of [`avr-libc`](https://github.com/avrdudes/avr-libc/tags) from [`avrdudes/avr-libc`](https://github.com/avrdudes/avr-libc) and build it with its `--prefix` matching that of the above-mentioned `avr-gcc`-build.
+  - Get the main branch of [`avr-libc`](https://github.com/avrdudes/avr-libc/tags) from [`avrdudes/avr-libc`](https://github.com/avrdudes/avr-libc) and build it with its `--prefix` matching that of the above-mentioned `avr-gcc`-build.
   - Test the complete, newly built `avr-gcc` toolchain with a non-trivial compiler test. In the compiler test, we build `ref_app` (the reference application) from [`ckormanyos/real-time-cpp`](https://github.com/ckormanyos). Verify the creation of key build results from `ref_app` including ELF-file, HEX-file, map files, etc.
