- Everything now builds as PIC by default no matter the toolchain's settings. Use the --disable-all-pic configure option to build executables and static libraries as non-PIC.
- This is a major version release of s6. It is recommended to first stop all your s6 services, then upgrade, then immediately restart your supervision tree, then start your services again. Failure to do so *will* cause issues if you're relying on s6-ftrigrd notifications (which is the case, for instance, with services managed by s6-rc).
