 The Dockerfile is the basis of the devcontainer and can be changed to add or remove tools. It will take a long time to build locally, so by default the devcontainer will pull a prebuilt version. Edit `.devcontainer/devcontainer.json` if you would rather build your own.

-No breaking changes, but this version brings full support for Apple silicon which was not present in previous releases.
+The base has been updated from Ubuntu 24.04 to Ubuntu 26.04, largely to bring in python 3.14 which is required for the current release of Boriel BASIC. This may cause some issues, so please report bugs. z88dk is still being built on 24.04 but should be ABI compatible. Again, please report any bugs you find.
