Bug#1028452: unblock: golang-1.19/1.19.5-1
Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock
X-Debbugs-Cc: golang-1.19@packages.debian.org, zhsj@debian.org
Control: affects -1 + src:golang-1.19
Please unblock package golang-1.19
This is a point release for golang 1.19 which happens today.
[ Reason ]
Update the latest release.
[ Impact ]
If we can be closer to upstream latest release, it will be easier to backport
security patch for bookworm.
[ Tests ]
Upstream does well tests. And I have tried to use the new version to compile
some programs.
[ Risks ]
The history record for golang point release doesn't show regressions.
[ Checklist ]
[x] all changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in testing
[ Other info ]
+ This package doesn't have autopkgtest.
+ Many Go packages still record Built-Using field, so this upload will block
Go packages from migration. Release team need to rebuild outdated Built-Using.
The Go point release or security release may happen several times during freeze.
What kind of release can be expected to be unblocked during freeze?
