+## Deprecations/Removals
+
+### TI-specific toolchains
+
+My usage of TI-specific toolchains was dropped in favour of using Yocto or Buildroot directly, as the TI pre-packaged toolchains have a slow release/support cycle. I considered these Dockerfiles deprecated as of March 31, 2022 - and they were removed on June 12, 2024
+
+### arm-none-eabi-gcc
+
+Support was been dropped in favour of the similar (and more consistently named) `robotpajamas/gcc-arm-none-eabi` starting on March 31, 2022 - and the associated Dockerfile was removed on June 12, 2024.
