== Build steps ==

* Make sure dmd/VERSION contains the to be build version
* Combining the changelog
** copy the changelog.dd parts from the dmd/druntime/phobos stable repos to a new dlang.org/changelog/2.068.1.dd
** use tools/changed to get the bugzilla changelog list
** Update prev/next navigation in changelogs
** Update dlang.org/win32.mak

* Test building the stable branch
** cd installer/create_dmd_release
** rdmd build_all v2.068.0 stable
** possibly fix build script, repos, or update patches

* Tag a new version

Push the tags to your private forks (origin) first to test whether the release builds cleanly. Tags on upstream '''must''' not be changed ever. To build from your private forks you need to change the base url in [https://github.com/D-Programming-Language/installer/blob/e5c8c60295e5d83c086d98f08978273059dec24d/create_dmd_release/build_all.d#L336 cloneSources].

<code>
  for proj in dmd druntime phobos tools dlang.org installer; do
    pushd $proj
    git fetch upstream
    git tag -sm 'v2.068.1-b1' v2.068.1-b1 upstream/stable
    git push origin v2.068.1-b1
    popd
  done
</code>

* Build binaries
** cd installer/create_dmd_release
** rm -rf build
** rdmd build_all v2.068.0 v2.068.1-b1

* Sign binaries

<code>
  for file in build/*; do
    gpg2 -b $file
  done
</code>

* Perform additional tests
* Upload binaries
** <code>rsync --progress -av --chmod=ug=rw build/ martin@digitalmars.com:/var/pub/digitalmars.com/</code>
** Upload to releases or pre-releases
*** <code>aws --profile ddo s3 sync build/ s3://downloads.dlang.org/pre-releases/$(date '+%Y')/ --acl public-read --cache-control max-age=604800</code>
*** <code>aws --profile ddo s3 sync build/ s3://downloads.dlang.org/releases/$(date '+%Y')/ --acl public-read --cache-control max-age=604800</code>
*** Make sure to check for errors during upload and probably repeat

* If everything went right until here, push the tags to upstream

<code>
  for proj in dmd druntime phobos tools dlang.org installer; do
    git -C $proj push upstream v2.068.1-b1
  done
</code>

* Update downloads.dlang.org
** cd downloads.dlang.org (https://github.com/braddr/downloads.dlang.org)
** ls create_dmd_release/build >> make-links
** edit 'make-links' and add symlinks for all the new files
** run <code>./make-links</code>
** build <code>make -C src</code>
** and run <code>./src/build-gen-index s3_index generate</code> to regenerate the download pages to ./ddo
** <code>aws --profile ddo s3 sync ./ddo/ s3://downloads.dlang.org/ --acl public-read --cache-control max-age=604800</code>
** commit and push changes to downloads.dlang.org

* Update LATEST
** ssh martin@digitalmars.com 'echo -n 2.069.0 > /var/pub/digitalmars.com/LATEST'
* Merge stable branches into master

<code>
  cd dmd # repeat for every repo
  git fetch upstream
  git checkout -b merge_stable upstream/master
  git merge upstream/stable
  # fix any conflicts
  git hub pull new -b master
</code>
* Rebuild and sync dlang.org
* Use a tool like [https://github.com/ocodia/Check-My-Links/ Check-My-Links] to check the download pages
* Write an announcement to digitalmars.D.announce and/or dmd-beta.
* Update the version in D's [https://en.wikipedia.org/wiki/D_(programming_language) Wikipedia article]
* Publish announcements to Twitter, Reddit, HackerNews, Slashdot (make noise!)
* Update DMD version in this [[Template:Latest_DMD_Version_Raw|D wiki]]
