A note on binaries

Official binaries will not be available right away with RC1. We hope to provide them later on.

Third-party binaries will be posted to the following forum thread. Note that these binaries are not created or checked by the release managers, they should be used with care.

Next release

The next release will be 19.1.0-rc2 the 6th of August . Please file issues you find in the 19.x milestone.

Does this mean “later on in the 19.1.0 release process” or is that yet to be determined?

We are still working on some of the automation to build them (see workflows/release-binaries: Always pull composite actions from main branch by tstellar · Pull Request #100805 · llvm/llvm-project · GitHub) The plan is to do builds for 19.1.0-rc1, but we’ll see what happens.
