The release candidates for the third 1.69.0 beta release are now available at: https://dl.bintray.com/boostorg/beta/1.69.0.beta1.rc3/source/

As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy.
