  • Updated the Apache and IANA media registry entries as of release date

3.2023.0218.1 / 2023-02-18

  • When this data library was created in 2015, I made the decision based on information available to deprecate text/javascript in favour of application/javascript. Since the previous update (2022-01-05), IANA has officially deprecated application/javascript in favour of text/javascript. Samuel Williams discovered this in #55 by noting that all js types were marked obsolete in version 3.2023.0218.

    A hotfix has been applied to resolve this. However, note that application/javascript will not be returned by default, only text/javascript.

3.2023.0218 / 2023-02-18

  • Updated the Apache and IANA media registry entries as of release date.

  • Mohammed Gad added the jfif file extension for image/jpeg text format. #52

  • Reworked the loading of IANA provisional media registries to merge them into the top-level media-type registries instead of a standalone registry file. #53 originally identified by Chris Salzberg in #50.

    It is worth noting that this is an imperfect solution as if a media type is provisionally registered and withdrawn, it will linger in the registry with no clean way of identifying them at the moment. See #54.

    This release also fixes ruby-mime-types#163, where logs show "Type application/netcdf is already registered as a variant of application/netcdf".

3.2022.0105 / 2022-01-05

  • Updated the Apache and IANA media registry entries as of release date.

  • Fixed an incorrect definition of image/bmp, which had been marked obsolete and later registered. Fixed #48, found by William T. Nelson.

3.2021.1115 / 2021-11-15

  • Updated the Apache and IANA media registry entries as of release date.

  • Added conversion utilities that support the mini_mime data format. These have been ported from the mini_mime repository. #47

  • Added IANA provisional media registries. Added some notes to Contributing.md about the transient nature of the provisional registration data. This was triggered in part by a pull request by Jon Sneyers. Thanks! #45, #43

3.2021.0901 / 2021-09-01

  • Added application/x-zip-compressed. #36

  • Because of a bug found with mime-types 3 before 3.2.1, this version requires mime-types 3.1 or later to manage data.

  • Updated the IANA media registry entries as of release date. The biggest major change here is the addition of the font/ top-level media type.

  • MIME type changes not introduced by pull requests will no longer be individually tracked.

  • Clarified that the YAML editable format is not shipped with the Ruby gem for size considerations.

    • image/bmp has a draft RFC which would make it official; it has been finally been registered. As such, this version reverses the use-instead relationship of image/bmp and image/x-bmp.
