Late as always, but it seems like not too late :) I tried added everyone who contributed to the static analyzer in a meaningful way, but if you did and don't find yourself on the reviewer list, please add yourself! I compiled these notes from the following list: git log llvmorg-11-init..llvmorg-11.0.0-rc2 --oneline -- clang/lib/StaticAnalyzer/ clang/include/clang/StaticAnalyzer/ Seems like this is a release to be proud of!
