How to make a ScummVM release.

This is work in progress and needs to be completed!

All examples are based on 1.7 and 1.7.0 version. Don't forget to adapt with the adequate version.


Preparations

  • Make the release plan, normally 1-2 weeks before branching, 3-4 weeks for bug fixing, 2 weeks after tagging before the release
    • e-mail -devel with the proposed schedule, ask if someone would like to finish some functionality
    • Look through all the open issues on the bugtracker and identify release blockers and nice-to-have-fixed bugs
  • Update the lists of files below, adding new engine data files and such
  • If some games must be fixed before the release, identify those and create a list at Release Testing
  • Announce the testing period on the main website and copy to the forums and FB

During the release cycle

  • E-mail the scummvm-devel list at least weekly with the list of release blockers and nice-to-have-fixed bugs
  • Track daily testing progress and update Wiki if applicable. Normally, we collect playtests on the forums
  • Watch for any potential blockers and pat developers who own the identified blockers
  • Squash as many bugs as possible

Branching for major release

  • Create a branch for the 2.2.x releases from master, named branch-2-2
    • git checkout -b branch-2-2 master
  • Increase version on branch-2-2 to 2.2.0pre (using devtools/update-version.pl; see below), and commit
    • devtools/update-version.pl 2 2 0 pre
    • git commit -m "RELEASE: This is 2.2.0pre" -a
  • Create annotated tag desc/2.2.0pre on that commit and push
    • git tag -a -m "Mark 2.2.0pre" desc/2.2.0pre
    • git push origin tag desc/2.2.0pre branch-2-2:branch-2-2
  • Increase version on master to 2.3.0git, and commit
    • git checkout master
    • devtools/update-version.pl 2 3 0 git
    • git commit -m "RELEASE: This is 2.3.0git" -a
  • Create annotated tag desc/2.3.0git on that commit and push
    • git tag -a -m "Mark 2.3.0git" desc/2.3.0git
    • git push origin tag desc/2.3.0git master
  • Update buildbot
    • Edit at the end of builds.py the line starting with builds.append(ScummVMStableBuild("stable",.
    • Remove the customizations in class ScummVMStableBuild if there were any to make the code inherit from ScummVMBuild without any difference.
    • Edit the file platforms.py and remove all specific rules mentioning ScummVMStableBuild
    • Update the code on the server and reload the buildbot as described here
    • Remove the old snapshots: rm /home/buildbot/dockerized-bb/buildbot-data/packages/snapshots/stable/*
    • Login on Buildbot, force a build of fetch-stable with cleaning and packaging to create packages for the new stable.
  • Communication
    • Update IRC and Discord channel description
    • Write a mail to scummvm-devel

Testing

  • Ensure ADGF_TESTING/ADGF_UNSTABLE flags are correct for the release.
  • Identify release critical (show stopper) bugs and get people to fix them.
  • Identify other important bugs and get people to fix them.
  • Get even more people to fix all the other bugs, if possible :-).
  • Get people to do lots of testing, possibly by asking for help via a news item.
  • Collect all that information (e.g. in the Wiki). See Release Testing

Preparing the source

  • Browse 'git log' since the previous release and add all significant changes to the NEWS file
  • Make sure the translations.dat file is up to date. This file is automatically generated once per week (on Monday morning) and may need to be updated manually if changes to the translations occurred since the last Monday. Use make translations-dat to update the file (and then commit it if it was changed).
  • You have to update the versions in all relevant files. There is a script, devtools/update-version.pl meant to help you with this. It will generate/update the following files:
    • base/internal_version.h
    • dists/macosx/Info.plist
    • dists/redhat/scummvm.spec
    • dists/scummvm.rc
  • Review the following documentation files for version and copyright year updates:
    • README(.md)
    • NEWS(.md)
    • COPYRIGHT
  • Make sure ADGF_TESTING flag is cleared on all games.
  • Review the following port specific files for version updates:
    • backends/platform/psp/README.PSP
    • backends/platform/symbian/README
  • Review the release dates in the following port specific files:
    • dists/win32/scummvm.gdf.xml
  • Make sure package descriptions are up-to-date:
    • dists/redhat/scummvm.spec
  • Create MSVC project files in the release branch (for example branch-1-7-0, where the tarballs are created from)
    • make ideprojects
    • git commit -m "DISTS: Generated Code::Blocks and MSVC project files"
    • And last but not least don't forget to push the results to our github repo via "git push"
  • Make source tarballs, put them in the FRS directory.
    • There is a script devtools/dist-scummvm.sh, which creates them automatically.
    • Make sure that porters have write access to the release folder on FRS: chmod 775 <folder>
  • Follow the instructions at HOWTO-Release#Signing binaries in order to enable updates via (Win)Sparkle

Branching for minor releases

  • Create a branch for 1.7.0 from branch-1-7, named branch-1-7-0
    • git checkout -b branch-1-7-0 branch-1-7
  • Increase version on branch-1-7-0 to 1.7.0 and commit, push
    • devtools/update-version.pl 1 7 0
    • Manually edit backends/platform/maemo/debian/changelog to reflect correct release date for 1.7.0 entry
    • git commit -m "RELEASE: This is 1.7.0" -a
    • git push origin branch-1-7-0:branch-1-7-0

Binaries

  • Get porters to make binaries.
    • Porter must follow our filename convention, which goes like this: "scummvm-VERSION-PORT.EXTENSION". For example: "scummvm-1.1.0-macosx.dmg". Do not use special names like "EScummVM" or "ScummVMDS". The only exclusion from this requirement is Debian.
    • Porters should pass "--enable-release" to configure in case their port is using the configure/make based build system. If their port is not using the configure/make based build system they should make sure they properly define RELEASE_BUILD when compiling their release binary. It is also noteworthy that "--disable-debug" should be passed in order to remove debugging information from the binary.
    • Here is a list of files porters should include in their release archives:
      • AUTHORS
      • COPYING
      • COPYING.BSD
      • COPYING.FREEFONT
      • COPYING.LGPL
      • COPYING.OFL

      • xeen.ccs (from dists/engine-data)
      • your build binary
      • your build-specific README (optional)
      • ...
  • Porters need to upload binaries at some service and then send the link to the team member managing the release (this should be detailed in the email sent to porters with the links to the tarballs).
  • Update the website internally (i.e. update the version in the repository), but do not yet put these changes online.
    • Edit include/config.inc.php to update the global version.
    • Create a new XML file for the new version in data/compatibility/.
    • Update data/downloads.xml.
    • Add a news item.
    • Follow the instructions at HOWTO-Release#Signing binaries in order to enable updates via (Win)Sparkle
    • Copy over the release files to FRS
      • Set the OS for the newly uploaded binaries (click on the (i) next to each binary).
        • -win32.exe as Windows binary
        • -macosx.dmg as Mac binary
        • .tar.bz2 as Linux, FreeBSD and Other binary
        • -solaris-x86.tar.gz as Solaris binary

Tagging a version

  • When 1.7.0 is ready to be announced, make a permanent v1.7.0 tag in git to mark the release
    • git checkout branch-1-7-0
    • git tag -a -m "Tag v1.7.0" v1.7.0
    • git push origin tag v1.7.0
  • Also increase the version number on the 1.7.x branch to 1.7.1pre
    • git checkout branch-1-7
    • devtools/update-version.pl 1 7 1 pre
    • git commit -m "RELEASE: This is 1.7.1pre" -a
  • Create annotated tag desc/1.7.1pre on that commit and push
    • git tag -a -m "Mark 1.7.1pre" desc/1.7.1pre
    • git push origin tag desc/1.7.1pre branch-1-7:branch-1-7
  • Add this doc to the Read The Doc admin settings to generate the documentation for this version.

Creating source tarballs

Then you need to create and upload the tarballs. 

devtools/dist-scummvm.sh scummvm 1.9.0
devtools/dist-scummvm.sh scummvm-tools 1.9.0

Then upload the resulting scummvm-1.9.0.tar.gz, scummvm-1.9.0.tar.bz2, scummvm-1.9.0.tar.xz and scummvm-1.9.0.tar.zip to the FRS.


Signing binaries

Put tarballs into directory archives/, run: 

bin/generate_appcast archives/
bin/old_dsa_scripts/sign_update archives/scummvm-2.1.1-win32.exe dsa_priv.pem
bin/old_dsa_scripts/sign_update archives/scummvm-2.1.1-macosx.dmg dsa_priv.pem

The first line will generate file archives/release.xml. The following ones will just spit out DSA signatures.

Copy/paste signatures to dists/macosx/scummvm_appcast.xml in the main git repo.

Then run: 

make publish-appcast
cd ../scummvm-web
git commit -m 'WEB: Sync appcast' -a

News & Notification

Write a news blurb (or rather multiple to be used in the following). Usually, you want a bit longer one for the website, a list for Versiontracker, something with proper english sentences for Freshmeat, etc....

  • Write a news item for our website (also to be used as a template for news items on other sites).
    • Change version constants in include/Constants.php
    • Put Release Notes into two files in the release directory, one is plain text, named "ReleaseNotes", another one is HTML, use markdownhtml.com service but copy the HTML body tags from the previous release.
    • Make sure to update the Release information in the datasheet
    • Make sure Sparkle appcast is updated (see #Signing binaries)
  • Update / notify various sites:
    • Post about the release on our forums
    • Post about the release on Facebook
    • Post link to the news item to Twitter
  • Put the updated web site online
  • Update IRC and Discord channel topics

GitHub release

Use https://github.com/scummvm/scummvm/releases/new for creating a new GitHub release:

  • Use the current tag as "base" for the release
  • Use the current version number as "Release title" (format: 1.2.3, no leading "v")
  • Use the current ReleaseNotes in Markdown format for the "Describe this release" field
  • GitHub automatically attaches the matching source tarball in .zip and .tar.gz format, so no need to upload it on your own

Updating the wiki

  • Update Template:StableVersion. This is used for links to the Compatibility page for the stable version and for the latest stable version info field for each platform.
  • Move newly supported engines in the Complete engines in the latest stable version section on the Engines page.
  • Add the first release field on the info box of the newly supported engines.
  • Update Platforms page if status changed for some of the platforms (e.g. no release for the latest stable version). For these platforms the latest stable version info will also need to be changed if it was using the StableVersion template.
  • Set the First Official Version field for new platforms.
  • Update the support field on the info box of the newly supported games. Also change these games from Unsupported Games category to Supported Games category.
  • Update the compatibility data at the ScummVM Data spreadsheet flip DEV with the release number
