Do this in a proper PR pointing to the release branch as this gives others the opportunity to chime in on the release in general and on the addition to the changelog in particular. For a release candidate, append something like `-rc.0` to the version (with the corresponding changes to the tag name, the release name etc.). +When updating the `CHANGELOG.md` look at all PRs included in the release since the last release and verify if they need a changelog entry. + Note that `CHANGELOG.md` should only document changes relevant to users of Prometheus, including external API changes, performance improvements, and new features. Do not document changes of internal interfaces, code refactorings and clean-ups, changes to the build process, etc. People interested in these are asked to refer to the git history. For release candidates still update `CHANGELOG.md`, but when you cut the final release later, merge all the changes from the pre-releases into the one final update. diff --git a/VERSION b/VERSION index 867c356bb9..261d95596f 100644 --- a/VERSION +++ b/VERSION @@ -1 +1 @@ -2.52.0-rc.1 +2.53.0 diff --git a/cmd/prometheus/main.go b/cmd/prometheus/main.go index f2988b2f2d..7544f276a6 100644 --- a/cmd/prometheus/main.go +++ b/cmd/prometheus/main.go @@ -28,6 +28,8 @@ import ( "os/signal" "path/filepath" "runtime" + "runtime/debug" + "strconv" "strings" "sync" "syscall" @@ -443,6 +445,9 @@ func main() { serverOnlyFlag(a, "alertmanager.notification-queue-capacity", "The capacity of the queue for pending Alertmanager notifications.").
