Picard 1.2 released

Version 1.2 of Picard has been released today, with some notable features and bug fixes.

As announced recently, PUID support is being removed from MusicBrainz on October 15. This release of Picard has followed suit by removing all support for AmpliFIND/PUID scanning and submission. AcoustID is now the default (and only) method of scanning files. If you’re currently using AmpliFIND as your fingerprinting system, then after installing Picard 1.2 you must enable AcoustID in your options, under the “Fingerprinting” section.

Those who have the Picard cover art plugin installed will likely want to remove it. Picard 1.2 has built-in support for downloading cover images from a variety of sources, without the need for a plugin. Please see the new configuration under Options -> Cover Art.

Something important to note for people who build/package Picard is that Python 2.6 is now the minimum required version.

Special thanks to Wieland Hoffmann, Laurent Monin, Lukáš Lalinský, and everyone who’s helped contribute/report bugs for this release!

Picard 1.2 can be downloaded at:

Changes since 1.1:

  • Picard now requires at least Python 2.6
  • Removed support for AmpliFIND/PUIDs
  • Add support for the Ogg Opus file format
  • It’s now possible to download cover images without any plugin. Cover Art Archive images can be downloaded by image type

  • Prefer already-loaded releases of the same RG when matching files
  • Allow dropping new files onto specific targets
  • Add basic collections management support (PICARD-84)
  • Allow adding custom tags in the tag editing dialog (PICARD-349)
  • Fix replacing of Windows-incompatible characters (PICARD-393)
  • Save both primary and secondary release types (PICARD-240)
  • Handle errors from the AcoustID service better (PICARD-391)
  • Accept HTTPS URLs on drag-and-drop (PICARD-378)

Updated search server now live

We’ve just updated our search servers to the latest version. Thanks to Paul Taylor for his long hard work porting our code to Lucene 4.1. Big thanks also to Murdos and Nikki for helping with this release!

Also, we’ve installed a small gigabit ethernet switch for our search server cluster so that we can move new search indexes around much faster. Hopefully we will see indexes updating in just over 2 hours from now on.

Read on for all the details of this release:

Task

Updating our privacy policy

A number of bugs have been piling up pointing out inconsistencies in our privacy policy. We’ve realized that the existing privacy policy is quite brittle with respect to our fast paced server development cycle. I’ve edited the privacy policy in an attempt to future proof the policy while not eroding anyone’s privacy. The revised policy has already had some community review and now I would like to cast the net to a wider audience for review.

However, I would like to set the stage carefully here: This is not a call to re-write our privacy policy or to nit-pick it to pieces. I am trying to nail down the open bugs and ensure that our privacy policy reflects our current actual activities. So, unless you find an actual problem that needs to be addressed, I am not likely to make any further changes to the revised policy.

That said, here is the list of bugs I’m trying to close: MBS-5708, MBS-5709, OTHER-144, OTHER-145, MBS-5942, MBS-5948.

Here is the new privacy policy that should fix the bugs above. Compare that to our current policy and also have a look at the diff of the wiki markup between the two pages.

Server update 2013-03-25

We’ve just finished deploying changes from the last fortnight. This release is mostly bug fixes, but we also have a bit more validation when entering label URLs and some improvements to reports. Many thanks to Alastair Porter, Frederik “Freso” S. Olesen, Lukáš Lalinský, Nicolás Tamargo, Paul Taylor, Pavan Chander and the MusicBrainz team for their work on this release. Detailed changes follow:

  • [MBS-5947] – Changed AC display doesn’t detect unchanged gaps
  • [MBS-5953] – oauth: web application reauthorization creates table spam
  • [MBS-5958] – Release editor did something very very wrong
  • [MBS-5979] – Automatic redirect to beta clear release editor seeding
  • [MBS-5996] – Release and work level relationships getting mixed up in release pages

The Git tag for this release is v-2013-03-25.

PUIDs are deprecated and will be removed on 15 October, 2013

tl;dr: On 15 october, we’re going to: drop table PUID;

In 2006 we added support for PUID acoustic fingerprints from MusicIP. MusicIP went out of business some years ago and the PUID service has been passed along, through various hands. Along the way it became neglected and the quality of the service went downhill. This spurred the creation of AcoustID which is our preferred solution for fingerprinting inside MusicBrainz today. We set out to let AcoustID support and PUID support live side-by-side in MusicBrainz for a while and we feel that almost enough time has passed. Therefore we’re going to remove PUID support from MusicBrainz in our autumn schema change release on 15 October, 2013.

If you depend on PUID support today, we encourage you to move over to AcoustID as soon as possible.

Official schema change notification for 15 May, 2013

We’re nearly done implementing the SQL portions of our tickets for the upcoming schema change on 15 May, 2013. We’ve settled on the following tickets that we plan to release:

  • MBS-5861: Dynamic work attributes
  • MBS-3978: Support more than one barcode on same release
  • MBS-4756: Move the wiki transclusion index to the database
  • MBS-799: Location, venue and event support
  • MBS-3985: Support multiple artist countries
  • MBS-4925: Add country of birth and country of death to Artist (person)
  • MBS-4115: Cover art archive: Support .png SQL changes
  • MBS-1839: Track MBID SQL changes
  • MBS-5809: Add a “description” field to collections
  • MBS-5314: Drop the work.artist_credit column
  • MBS-5302: Store International Standard Name Identifier (ISNI, ISO 27729) for artists and labels
  • MBS-5528: Change short_link_phrase to long_link_phrase
  • MBS-2229: Allow multiple release events per release
  • MBS-2417: Support multiple countries/regions on a single release
  • MBS-5772: Generate relationship documentation (semi-)automatically
  • MBS-5848: Instrument credits

Each of the tickets above will give you a complete idea of how we plan to change our schema on May 15th. Questions? Post a question in the comments and we will answer it.

Finally, we are going to require that Postgres 9.1 will be the minimum version of Postgres going forward. I’ve spoken to many people about this and it seems that a large percentage of people are already using Postgres 9.1, so this should not be a major change.

Thanks!

Server Update, 2013-03-11

Thanks to work from Nicolás Tamargo, nikki, Lukáš Lalinský, Paul Taylor, and the MusicBrainz team, we’ve just released a new version of the MusicBrainz website. As usual, this is mostly a bug fix release, but we do have one shiny new feature once again… OAuth2! It is now possible to authenticate with MusicBrainz using this, rather than the old digest auth system. For more details, see the Development/OAuth2 documentation page. This feature is new, so if you encounter any problems (here or elsewhere), please be sure to let us know!
