# MIME Types Changes by Version ## 3.2024.0402 / 2024-04-02 - - Updated the Apache and IANA media registry entries as of release date ## 3.2024.0305 / 2024-03-05 - - Updated the Apache and IANA media registry entries as of release date ## 3.2024.0206 / 2024-02-06 - - Updated the Apache and IANA media registry entries as of release date ## 3.2024.0102 / 2024-01-02 - - Updated the Apache and IANA media registry entries as of release date ## 3.2023.1205 / 2023-12-05 - - Updated the Apache and IANA media registry entries as of release date ## 3.2023.1107 / 2023-11-07 - - Updated the Apache and IANA media registry entries as of release date ## 3.2023.1003 / 2023-10-03 - - Updated the Apache and IANA media registry entries as of release date ## 3.2023.0905 / 2023-09-05 - - Updated the Apache and IANA media registry entries as of release date ## 3.2023.0808 / 2023-08-08 - - 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 It is worth noting that this is an _imperfect_ solution as if a media type is provisionally registered and withdrawn, it will linger in the registry with no clean way of identifying them at the moment.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 - Updated the Apache and IANA media registry entries as of release date. - Added file extension for WebVTT text format. [#46][] ## 3.2021.0704 / 2021-07-04 - Updated the Apache and IANA media registry entries as of release date. ## 3.2021.0225 / 2021-02-25 - Updated the Apache and IANA media registry entries as of release date. - Added file extension for AVIF video format. [#40][] ## 3.2021.0212 / 2021-02-12 - Updated the IANA media registry entries as of release date. - Added a new rake task (`release:automatic`) that downloads and converts the data from Apache and IANA; if there are changes detected, it updates the release version, changelog, manifest, and gemspec and commits the changes to git. ## 3.2020.1104 / 2020-11-04 - Updated the IANA media registry entries as of release date. - Added `application/x-zip-compressed`. [#36][] - Updated the contributing guide to include information about the release process as described in [#18][] - Corrected a misspelling of Yoran Brondsema’s name. Sorry, Yoran. [#35][] ## 3.2020.0512 / 2020-05-12 - Updated the IANA media registry entries as of release date. - Added file extensions for HEIC image types. [#34][] ## 3.2020.0425 / 2020-04-25 - Updated the IANA media registry entries as of release date. - Added several RAW image types based on data from GNOME RAW Thumbnailer. [#33][] fixing [#32][] - Added `audio/wav`. [#31][] - Added a type for Smarttech notebook files. [#30][] - Added an alias for audio/m4a files. [#29][] - Added application/x-ms-dos-executable. [#28][] ## 3.2019.1009 / 2019-10-09 - Updated the IANA media registry entries as of release date. - Reordered the `.ai` extension so that it is not the preferred extension for `application/pdf` [#24][] ## 3.2019.0904 / 2019-09-04 - Updated the IANA media registry entries as of release date. - Moved the `.ai` extension from `application/postscript` to `application/pdf`. [#23][] fixing [#22][] ## 3.2019.0331 / 2019-03-31 - Updated the IANA media registry entries as of release date. - Added support for `application/wasm` with extension `.wasm`. [#21][] - Fixed `application/ecmascript` extensions. [#20][] ## 3.2018.0812 / 2018-08-12 - Added `.xsd` extension to `text/xml`. [#10][] - Added `.js` and `.mjs` extensions to `text/ecmascript` and `text/javascript`. [#11][] - Added `.ipa` extension to `application/octet-stream`. [#12][] - Moved extensions `.markdown` and `.md` and added `.mkd` extension to `text/markdown`. [#13][] - 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. ## 3.2016.0521 / 2016-05-21 - Updated the known extension list for application/octet-stream and application/pgp-encrypted to include gpg as an extension. Fixes [#3](https://github.com/mime-types/mime-types-data/pull/3) by Tao Guo (@taoza). - Updated the IANA media registry entries as of release date: - Updated metadata for application/EmergencyCallData.Comment+xml, application/EmergencyCallData.DeviceInfo+xml, application/EmergencyCallData.ProviderInfo+xml, application/EmergencyCallData.ServiceInfo+xml, application/EmergencyCallData.SubscriberInfo+xml, application/ogg, application/problem+json, application/problem+xml, audio/ogg, text/markdown, video/H265, video/ogg. - Added application/efi, application/vnd.3gpp.sms+xml, application/vnd.3lightssoftware.imagescal, application/vnd.coreos.ignition+json, application/vnd.oma.lwm2m+json, application/vnd.onepager, application/vnd.quarantainenet, application/vnd.vel+json, image/emf, image/wmf, text/prs.prop.logic. - 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. - This version requires mime-types 3.1 or later to manage data because of an issue with JSON data encoding for the `xrefs` field. ## 3.2016.0221 / 2016-02-21 - Updated the known extensions list for audio/mp4. - Updated the IANA media registry entries as of release date: - Updated metadata for 3GPP-defined types (there are many), application/cdni, and application/rfc+xml. - Added application/EmergencyCallData.Comment+xml, application/EmergencyCallData.DeviceInfo+xml, application/EmergencyCallData.ProviderInfo+xml, application/EmergencyCallData.ServiceInfo+xml, application/ppsp-tracker+json, application/problem+json, application/problem+xml, application/vnd.filmit.zfc, application/vnd.hdt, application/vnd.mapbox-vector-tile, application/vnd.ms-PrintDeviceCapabilities+xml, application/vnd.ms-PrintSchemaTicket+xml, application/vnd.ms-windows.nwprinting.oob, application/vnd.tml, model/vnd.rosette.annotated-data-model, and video/H265. - Updated to [Contributor Covenant 1.4][code of conduct]. - Shift the support code in this repository to be developed with Ruby 2.3. This involves: - Adding `frozen_string_literal: true` to all Ruby files. - Applied some recommended readability and performance suggestions from Rubocop. Ignored some style recommendations, too. - Replaced some cases of `foo.bar rescue nil` with `foo&.bar`. ## 3.2015.1120 / 2015-11-20 - Extracted from [ruby-mime-types][rmt]. - Added a [Code of Conduct]. - The versioning has changed to be semantic on format plus date in two parts. - All registry formats have been updated to remove deprecated data. - The columnar format has been updated to store three boolean flags in a single flags file. - Updated the conversion and management utilities to work with ruby-mime-types 3.x. - Updated the IANA media registry entries as of release date: - Updated metadata for application/scim+json, audio/G711-0, text/markdown. - Added application/cdni, application/csvm+json, application/rfc+xml, application/vnd.3gpp.access-transfer-events+xml, application/vnd.3gpp.srvcc-ext+xml, application/vnd.3gpp.SRVCC-info+xml, application/vnd.ms-windows.devicepairing, application/vnd.ms-windows.wsd.oob, application/vnd.oxli.countgraph, application/vnd.pagerduty+json, video/VP8. ## 2.6.2 / 2015-09-13 - Updated the IANA media registry entries as of release date: - Updated metadata for application/cals-1840, application/index.obj, application/ocsp-response, application/vnd.dtg.local.html, application/vnd.pwg-multiplexed, audio/G7221, audio/opus. - Added application/pkcs12, application/scim+json, multipart/form-data. application/vnd.3gpp-prose+xml, application/vnd.3gpp-prose-pc3ch+xml, application/vnd.3gpp.mid-call+xml, application/vnd.3gpp-state-and-event-info+xml, application.3gpp.ussd+xml, application/vnd.anki, application/vnd.biopax.rdf+xml, application/vnd.drive+json, application/vnd.firemonkeys.cloudcell, application/vnd.hyperdrive+json, application/vnd.openblox.game+xml, application/vnd.openblox.game-binary, application/vnd.uri-map, audio/G711-0, image/vnd.mozilla.apng. ## 2.6 / 2015-05-25 - Steven Michael Thomas (@stevenmichaelthomas) added `woff2` as an extension to application/font-woff, [ruby-mime-types#99][]. - Updated the IANA media registry entries as of release date: - Updated metadata for application/jose, application/jose+json, application/jwk+json, application/jwk-set+json, application/jwt to reflect the adoption of RFC7519. - Added application/vnd.balsamiq.bmpr. ## 2.5 / 2015-04-25 - Updated the IANA media registry entries as of release date: - Added MIME types: application/A2L, application/AML, application/ATFX, application/ATXML, application/CDFX+XML, application/CEA, application/DII, application/DIT, application/jose, application/jose+json, application/json-seq, application/jwk+json, application/jwk-set+json, application/jwt, application/LXF, application/MF4, application/rdap+json, application/vnd.apache.thrift.compact, vnd.apache.thrift.json, application/vnd.citationstyles.style+xml, application/vnd.coffeescript, application/vnd.enphase.envoy, application/vnd.fastcopy-disk-image, application/vnd.gerber, application/vnd.gov.sk.e-form+xml, application/vnd.gov.sk.e-form+zip, application/vnd.gov.sk.xmldatacontainer+xml, application/vnd.ims.imsccv1p1, application/vnd.ims.imsccv1p2, application/vnd.ims.imsccv1p3, application/vnd.micro+json, application/vnd.microsoft.portable-executable, application/vnd.msa-disk-image, application/vnd.oracle.resource+json, application/vnd.tmd.mediaflex.api+xml, audio/opus, image/vnd.zbrush.pcx, text/csv-schema, text/markdown (marked as TEMPORARY). - Updated metadata for application/coap-group+json (RFC7390), application/epub+zip (now registered), application/merge-patch+json (RFC7396), application/smil, application/vnd.arastra.swi, application/vnd.geocube+xml, application/vnd.gmx, application/xhtml+xml, text/directory. - Andy Brody (@ab) fixed a pair of embarrassing typos in text/csv and text/tab-separated-values, [ruby-mime-types#89](https://github.com/mime-types/ruby-mime-types/pull/89). - Aggelos Avgerinos (@eavgerinos) added the unregistered MIME type image/x-ms-bmp with the extension `bmp`, [ruby-mime-types#90](https://github.com/mime-types/ruby-mime-types/pull/90). ## 2.4.2 / 2014-10-15 - Added application/vnd.ms-outlook as an unregistered MIME type with the extension `msg`.
