If you have an enhancement targeting 1.37, the blog freeze on July 9-10 is the next gate — docs and feature posts need to be in shape before code freeze. Code and test freeze land July 22-23, after which only bug fixes and release-blocking items can merge. The August 26 GA date keeps the cycle on roughly a four-month cadence from the 1.36 release. Teams running pre-GA builds in staging should plan upgrade testing windows around late July.
