On Thursday, we created 1.83.0 RC1. There have been two problems reported against it. * A couple of missing “include” statements in Unordered * A regression against 1.82.0 (code that used to compile no longer does) in Stl_interfaces. https://github.com/boostorg/stl_interfaces/issues/62 Zach has opined to me that this failure in stl_interfaces is deliberate; so we will not be addressing that. We will be producing an RC2 later today/early tomorrow with the fix for Unordered. This means that the release will probably NOT happen on Wednesday, 9-Aug. Hopefully Thursday. — The release managers.
