## 3.2025.0819 / 2025-08-19

- Updated registry entries from the IANA [media registry][registry] and
  [provisional media registry][provisional], the
  [Apache httpd media registry][httpd], and the
  [Apache Tika media registry][tika] as of the release date.

## 3.2025.0812 / 2025-08-12

- Updated registry entries from the IANA [media registry][registry] and
  [provisional media registry][provisional], the
  [Apache httpd media registry][httpd], and the
  [Apache Tika media registry][tika] as of the release date.

## 3.2025.0805 / 2025-08-05

- Updated registry entries from the IANA [media registry][registry] and
  [provisional media registry][provisional], the
  [Apache httpd media registry][httpd], and the
  [Apache Tika media registry][tika] as of the release date.

## 3.2025.0729 / 2025-07-29

- Updated registry entries from the IANA [media registry][registry] and
  [provisional media registry][provisional], the
  [Apache httpd media registry][httpd], and the
  [Apache Tika media registry][tika] as of the release date.

- Remove `.doc` from `text/plain`: The use of `.doc` for `text/plain` documents
  is mostly a holdover from VAX VMS where the default wasn't `.txt` but `.doc`.
  The world now thinks that `.doc` mostly means `application/msword` even though
  that format is obsolete by almost twenty years. Closes
  [ruby-mime-types#224][ruby-mime-types#224] with [#191][pull-191].

- Handle promoted and withdrawn provisional IANA media types. Closes
  [#54][issue-54] with [#192][pull-192].

  The logic is three relatively simple phases:

  1. When loading an existing registry grouping (such as
     `types/application.yaml`), we mark any type that is `provisional` as
     `obsolete`. This indicates that we consider any provisional type as
     potentially withdrawn (and therefore obsolete).
  2. When processing existing regular types, we clear both `provisional` and
     `obsolete` flags so that a type promoted from provisional is now a regular
     registry entry.
  3. After merging the current list of registry entries, we _clear_
     `provisional` if the type is marked both `provisional` and `obsolete`,
     indicating that the provisional type has been withdrawn.

  These heuristics match several types which have been promoted and withdrawn
  since the handling of provisional types was improved with [#53][pull-53].

## 3.2025.0722 / 2025-07-22

## 3.2025.0527 / 2025-05-27

## 3.2025.0520 / 2025-05-20

  [Apache Tika media registry][tika] as of the release date.

## 3.2025.0507 / 2025-05-07

- Added new data for pre-computed priority sorting. This new data requires Ruby
  mime-types 3.7.0 or later to manage data but is ignored by older versions of
  mime-types.

- Added a parser for the [Apache Tika media registry][tika] to enrich the media
  definitions, mostly by adding new patterns for media type extensions. This
  parser:

  1. Parses the current `tika-mimetypes.xml` from the main branch of
     [Tika][tika] on GitHub.

  2. Skips over any `mime-type` record that has attributes. That is, any record
     which looks like `media/subtype;format=foo` or `media/subtype;version=2`
     will be skipped. Support for attributes does not currently exist in the
     mime-types library.

  3. Extracts the `glob` entries for use in the `extensions` field. Globs that
     use `*` in the middle of a filename are excluded, because that's now how
     the Ruby MIME::Types field works (I could add a new `glob` field, but that
     will take a bit more work).

  4. Updates the `extensions` field for any existing MIME::Type or creates new
     unregistered (not defined in IANA) types for new ones.

- Updated the history body to reflect the new data source for updates.

- Some details were removed from older CHANGELOG entries relating to updated
  MIME types from more or less automated processes.

  changes merged normally are picked up on automatic releases. [#98][pull-98]

## 3.2025.0107 / 2025-01-07

## 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][issue-55] by noting that all `js`
  types were marked obsolete in version 3.2023.0218.

  A hot fix 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 registry entries from the IANA [media registry][registry] and
  [provisional media registry][provisional] and the
  [Apache httpd media registry][httpd] as of the release date.

- Mohammed Gad added the `jfif` file extension for `image/jpeg` text format.
  [#52][pull-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][pull-53] originally identified by Chris Salzberg in [#50][pull-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][issue-54].

  This release also fixes [ruby-mime-types#163][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 registry entries from the IANA [media registry][registry] and
  [provisional media registry][provisional] and the

## 3.2021.1115 / 2021-11-15

- Updated registry entries from the IANA [media registry][registry] and
  [provisional media registry][provisional] and the

  have been ported from the [mini\_mime][mini_mime] repository. [#47][pull-47]

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

  the changes to git.

  extension `msg`. Provided by [@keerthisiv](https://github.com/keerthisiv) in

  `application/vnd.ms-excel` per
  [ruby-mime-types#60](https://github.com/mime-types/ruby-mime-types/pull/60).

- Merged duplicate MIME types into the registered MIME type. The only difference
