 - [ ] ***(SwEng)*** Tag the releases[^2].  (Tags may only be pushed to the public repository for releases which are *not* security releases.)
 - [ ] ***(SwEng)*** If this is the first tag for a release (e.g. beta), create a release branch named `release_v9_X_Y` to allow development to continue on the maintenance branch whilst release engineering continues.
 ## Before the ASN Deadline (for ASN Releases) or the Public Release Date (for Regular Releases)
 - [ ] ***(QA)*** Verify GitLab CI results for the tags created and prepare a QA report for the releases to be published.
 - [ ] ***(QA)*** Request signatures for the tarballs, providing their location and checksums.
 - [ ] ***(Signers)*** Validate tarball checksums, sign tarballs, and upload signatures.
 - [ ] ***(QA)*** Verify tarball signatures and check tarball checksums again.
 - [ ] ***(Support)*** Pre-publish ASN and/or Subscription Edition tarballs so that packages can be built.
 - [ ] ***(QA)*** Build and test ASN and/or Subscription Edition packages.
 - [ ] ***(QA)*** Notify Support that the releases have been prepared.
 - [ ] ***(Support)*** Send out ASNs (if applicable).
 ## On the Day of Public Release
 - [ ] ***(Support)*** Wait for clearance from Security Officer to proceed with the public release (if applicable).
 - [ ] ***(Support)*** Place tarballs in public location on FTP site.
 - [ ] ***(Support)*** Publish links to downloads on ISC website.
 - [ ] ***(Support)*** Write release email to *bind-announce*.

 - [ ] ***(QA)*** Inform Marketing of the release.
 - [ ] ***(QA)*** Update the internal [BIND release dates wiki page](https://wiki.isc.org/bin/view/Main/BindReleaseDates) when public announcement has been made.
 - [ ] ***(Marketing)*** Post short note to Twitter.
 - [ ] ***(Marketing)*** Update [Wikipedia entry for BIND](https://en.wikipedia.org/wiki/BIND).
 - [ ] ***(Marketing)*** Write blog article (if a major release).
 - [ ] ***(QA)*** Ensure all new tags are annotated and signed.
 - [ ] ***(SwEng)*** Push tags for the published releases to the public repository.
 - [ ] ***(SwEng)*** Merge the automatically prepared `prep 9.X.Y` commit which updates `version` and documentation on the release branch into the relevant maintenance branch (`v9_X`).
 [^1]: If not, use the time remaining until the tagging deadline to ensure all outstanding issues are either resolved or moved to a different milestone.
 [^2]: Preferred command line: `git tag -u <DEVELOPER_KEYID> -a -s -m "BIND 9.X.Y[alphatag]" v9_X_Y[alphatag]`, where `[alphatag]` is an optional string such as `b1`, `rc1`, etc.

 - [ ] (Manager) Check for the presence of a milestone for the release:
    - If there is a milestone, are all the issues for the milestone resolved? (other than this checklist).
 - [ ] (Manager) Inform Support/Marketing of impending release (and give estimated release dates).
 - (SwEng) Prepare the sources for tarball generation:
   - [ ] Check perflab to ensure there has been no unexplained drop in performance for the version being released.
   - [ ] Ensure that there are no outstanding merge requests in the private repository (subscription version only).
   - [ ] Update API files for libraries with new version information.
   - [ ] Change software version and library versions in configure.in (new major release only).
   - [ ] Rebuild configure using autoconf on docs.isc.org.
   - [ ] Update CHANGES.
   - [ ] Update CHANGES.SE (subscription branch only).
   - [ ] Update "version".

   - Check the release notes are correct:
     - [ ] Compare content with merge requests for the release.
     - [ ] Check formatting.
   - [ ] Build documentation on docs.isc.org.
   - [ ] Commit changes and make sure the gitlab-ci tests are passing.
   - [ ] Push the changes and tag ("alphatag" is an optional string such as "b1", "rc1" etc.). (```git tag -u <DEVELOPER_KEYID> -a -s -m "BIND 9.X.Y[alphatag]" v9_X_Y[alphatag]```)
   - [ ] If this is the first tag for a release (e.g. beta), create a release branch named `release_v9_X_Y` (this allows development to continue on the release branch whilst release engineering continues).
 - [ ] (SwEng) Run the "make release" Jenkins job to produce the tarballs and zips.
 - [ ] (SwEng) Ask QA to sanity check the tarball and zips (passing to them the number of the Jenkins job).

 - [ ] (QA) Request the signature on the tarballs.
 - [ ] (QA) Check signatures on tarballs.
 - [ ] (QA) Tell Support to handle notification of release.

 BIND 9.15 requires a fairly recent version of `libuv` (at least 1.x).  For
 some of the older systems listed below, you will have to install an updated
 `libuv` package from sources such as EPEL, PPA, or other native sources for
 updated packages. The other option is to build and install `libuv` from
 source.
 Certain optional BIND features have additional library dependencies.
 These include `libxml2` and `libjson-c` for statistics, `libmaxminddb` for
 geolocation, `libfstrm` and `libprotobuf-c` for DNSTAP, and `libidn2` for
 internationalized domain name conversion.

      Metadata fields are stored in the private file.  A human-readable
