Release 0.9.453

On January 21, we deployed some major improvements to our bookmark search, including the ability to filter and sort bookmarks by word count!

  • [AO3-6301] - Series blurbs would list all fandom tags from the works included in that series, even if a work was still saved as an unpublished draft. Now series blurbs only display fandoms from posted works.
  • [AO3-6303] - Series blurbs would also always list fandoms from works that were restricted to logged-in users. We now make sure that if a fandom in a series comes from a restricted work, it's not listed when a guest is browsing series blurbs.
  • [AO3-6304] - Relatedly, series blurbs would always show up in bookmark listings for a certain tag even if that fandom's work in the series was restricted to logged-in users. That's also fixed now!
  • [AO3-6471] - We have added word count information to bookmarks! You can now search, filter, and sort bookmarks by the length of the bookmarked work or series. If a series contains restricted works and you're not logged in, a series' word count will reflect only the works that are accessible to you.
  • [AO3-7119] - We tweaked the way search queries work when searching bookmarks, so input is parsed more accurately and a "1k" and a "2k" tag won't be interpreted as the same tag anymore (for example).

Release 0.9.454

A small grab bag of fixes was released on January 26.

  • [AO3-7264] - We employ certain measures to prevent spam on AO3, such as limiting how many times an action can be performed by a user in a certain time frame. We have now added an option to restrict new accounts more severely than older accounts when it comes to leaving and editing comments.
  • [AO3-7238], [AO3-7262] - We added extra information to the details our spam-checking provider uses to determine if a comment is spam or not.
  • [AO3-7045], [AO3-7060], [AO3-7248] - Some database clean-up and dependency updates.

Release 0.9.455

On January 28, we deployed some of the necessary changes to enable two-step verification for AO3 admin accounts.

  • [AO3-6918] - These changes prepare the login interface for 2FA enforcement to ensure the greatest possible security for admin accounts.
  • [AO3-7249] - Site admins, such as members of the Policy and Abuse committee, frequently need to look up a user's past usernames and email addresses. To speed up searches while we work on long-term performance improvements, we moved this information to separate tables.

Release 0.9.456

A collection of navigation and display fixes was deployed on January 30.
