Server update, 2015-11-30

The major updates in today’s release are:

  • Non-auto-editors can make auto-edits to their release additions within 1 hour of adding them.
  • There’s a way to report editors for bad behavior, from their user profiles. The reports will be sent to our account admins. We’d prefer people use this method from now on for reporting unresponsive editors, or for any Code of Conduct violations. Account admins have also received an easy way to restrict a user’s editing/voting capabilities.
  • Auto-editors can change a release’s data-quality level via auto-edit. Previously, this was always put to a vote. We still don’t display release quality as well as we could (currently it’s only visible in the release sidebar). Low-quality releases can be found via our edit search, though.
  • Everyone can enter “Add recording” and “Remove alias” edit types as auto-edits.
  • Edits to events can be searched via our edit search interface (thanks chirlu).

There were a lot of comments on last release’s blog post saying that it’s harder to review release additions now that they’re auto-edits, and worrying about database quality suffering due to this. The next server release should allow showing auto-edits entered within the most recent voting period (7 days) in your subscribed editor/entity edit listings (MBS-8647), and hopefully a way to hide auto-edits you’ve reviewed from these lists (MBS-8654) to get them out of your way. I hope these and future changes can strike a balance between allowing people to see and remove releases that are clearly wrong or non-existent, vs. encouraging merging/fixing existing releases rather than voting them down.

The git tag for today’s release is v-2015-11-30 and the complete changelog is below.


  • [MBS-8460] – Add to collection link on entity page doesn’t show the collection name
  • [MBS-8636] – Adding duplicate entities to a series causes an internal server error
  • [MBS-8639] – Instrument merge gives ERROR: duplicate key value violates unique constraint “link_attribute_pkey”
  • [MBS-8641] – Release editor breaks with “error: 0” if a submitted edit throws a NoChanges exception
  • [MBS-8648] – Historic relationship edits no longer display the source entity


  • [MBS-1880] – Allow an editor to apply edits without voting within a short timeframe after his/her ‘add release’
  • [MBS-8208] – Add a way to report a user to an admin
  • [MBS-8271] – Add a way to prevent a user from editing/voting which doesn’t involve removing the email address

New Feature

  • [MBS-8645] – Allow searching for edits to events


  • [MBS-8385] – Make change release quality edits auto-edits for auto-editors
  • [MBS-8386] – Make add recording edits auto-edits for everyone
  • [MBS-8388] – Make remove alias edits auto-edits for everyone

Server update, 2015-11-16

Today we’ve released several changes decided at the recent MusicBrainz Summit:

  • German, French, and Dutch translations are now usable on the main server, via the language menu at the top right of any page. Previously these were only accessible on the beta server. Don’t forget to help contribute on Transifex if you find any issues in the translations. You can also help translate some of the less-complete languages over there.
  • “Add relationship” edits have been made auto-edits for everyone. By a recent calculation, only 0.78% of these have been canceled or voted down, yet they make up a large percentage of our open edits and are easy to remove.
  • “Add release” edits have been made auto-edits for everyone. Since releases added to MusicBrainz are available immediately through the website and web services, there’s no telling where the MBIDs are being used. Permanent and reliable IDs are a core tenet of MusicBrainz, so duplicate releases should always be merged to avoid MBID loss, not voted down or deleted. I’ll be looking at ways to better detect duplicates during the add-release process, though.
  • “Add release label” and “Remove release label” edits have been made auto-edits for everyone. Like the previous two edit types, release label additions are among the most common types of open edits, and are rarely canceled or voted down. Release label removals are also easy to revert because all of the removed data is contained in the edit.

In addition to the above changes, Roman Tsukanov has added some new reports, and we’ve fixed a few editing bugs.

The git tag today is v-2015-11-16 and the complete changelog is below.


      • [MBS-8607] – JSON-LD has bugs
      • [MBS-8612] – 404 page has incorrect/outdated menus
      • [MBS-8614] – Release merges can fail if a recording is both a merge source and merge target
      • [MBS-8615] – Non-conflicting mediums appended after a release merge is entered block the merge

Server update, 2015-11-02

Today’s release fixes some editing bugs and adds a useful option to the edit search for finding edits by newbie editors (those who have a low accepted-edit count). The git tag is v-2015-11-02 and the changelog is below.

(This release is a day late because I’d been traveling back from the MB summit all day yesterday.)

Server update, 2015-10-19

Today’s release fixes some bugs causing certain open edits to get stuck, and improves on our URL auto-selection code. Notably, URL shorteners are now detected and blocked from being entered.

The git tag is v-2015-10-19.


  • [MBS-8571] – Stuck edit: medium_positions does not account for all mediums in all releases
  • [MBS-8572] – Stuck edit: update or delete on table “recording” violates foreign key constraint “recording_alias_fk_recording” on table “recording_alias”

Server update, 2015-10-05

Besides the changes listed below, this release should mark the completion of the incremental sitemaps work required by Google. Practically, this means I’ll have more time to work on user-facing features from now on.

Thanks to Gentlecat and Zas for their work on today’s release. The git tag is v-2015-10-05.


  • [MBS-7828] – Seeding secondary types doesn’t work
  • [MBS-8553] – Internal server error when an automatic series reordering involves multiple of the same entity
  • [MBS-8561] – The entity type should be preselected when following an “Add to a new collection” link on an entities page


  • [MBS-8554] – Cache area containments
  • [MBS-8560] – Add Google Play to the sidebar

Server update, 2015-09-21

We just have a small release today, so I’ll let the changelog speak for itself. I’m currently focused on finishing implementing the hourly sitemaps required by Google (to indicate when our embedded JSON-LD markup last changed), and Roman Tsukanov is continuing to familiarize himself with our huge codebase. So, development in other areas will pick up in time. :)

The git tag for today’s release is v-2015-09-21.


  • [MBS-8370] – « Format: Medium » is shown instead of, for instance, « Format: CD »
  • [MBS-8534] – Label-only release label edits no longer display the catalog number


  • [MBS-8523] – For Places, rename “founded” and “defunct” to “opened” and “closed”

Server update, 2015-09-07

The 2015-09-07 server update is released today (a day late). Late because I wanted to investigate a fix for cover art uploading, which many people have reported issues with lately. Notwithstanding troubles at the Internet Archive, the server should hopefully give less errors now when uploading.

The other changes deal with edit-system bugs and URL cleanup enhancements.

Thanks to Gentlecat and reosarevok for their work on today’s release. The git tag is v-2015-09-07 and the changelog is below.


  • [MBS-8531] – Delete release label edits with no label fail to display
  • [MBS-8532] – Can’t edit a release label to add a label
  • [MBS-8533] – Catalog number-only release label edits no longer show in a MB Label’s edits

  • [MBS-8124] – Recognise and clean up URLs
  • [MBS-8182] – Improve Deezer URL cleanup
