= Set-up whatsnew page =
At the time of writing, manual work is required if we're shipping a release that has a mix of old versions that need/don't need a whatsnew page. If Release Management hasn't specified that a whatsnew page is needed, there's nothing to do. This must be done after initial update submission is done, and you'll need to know which where the cut off line for the whatsnew is. For example, when 35.0 shipped everything earlier than 34.0 required a whatsnew page, but 34.0 and 34.0.5 did not. If you don't grok how Balrog rules work it would be a good idea [[Balrog#Rules | to read up on them]] before getting started here.
Note: do not modify blobs until both "updates" builders have finished. Your changes may be overwritten otherwise.
To create a blob with the whatsnew page enabled, do the following:
* Find the release you're working on by filtering.
* Click "View Data".
* Paste the data into a local file.
* Edit the local file and add the following at the top level of the blob (replace $VERSION with the version of the release, do NOT replace %LOCALE% or %OLD_VERSION% - those are substituted by Balrog/Firefox):
"openURL": "https://www.mozilla.org/%LOCALE%/firefox/$VERSION/whatsnew/?oldversion=%OLD_VERSION%",
