2.2.0

New Features

• UTI-based file type detection — On Apple platforms, you can now detect file types directly from Uniform Type Identifier strings or UTType values using the new FileType.detect(uti:) and FileType.detect(utType:) APIs. Available when UniformTypeIdentifiers can be imported (macOS 11+, iOS 14+, tvOS 14+, watchOS 7+, visionOS 1+).

Improvements

• Platform and language configuration — Package now declares minimum platform versions and explicitly opts into Swift 6 language mode via swiftLanguageModes: [.v6], removing the need for per-declaration @available annotations.

2.1.0

New Features

• Streaming manifest detection — Detect HLS (m3u), MPEG-DASH (mpd), and Microsoft Smooth Streaming (ism) manifest files. HLS detection distinguishes HLS-specific playlists from generic M3U files by checking for #EXT-X- tags.

2.0.0

Changes since 1.1.2

Breaking Changes

• Swift 6.2 required — Minimum swift-tools-version bumped to 6.2
• API renames — Several methods have been renamed (old names still available as deprecated aliases)
• Byte-reading helpers now return optionals — Bounds-checked reads return nil instead of crashing on out-of-range access

New Features

• 40+ new file formats — ACE, APK, ARJ, Avro, CPIO, DWG, FBX, ICC, J2C, JAR, JLS, JMP, LZ4, Mach-O, Parquet, PCAP, PST, RealMedia, SPSS SAV, TTC, VTT, WebP, and many more
• Expanded Office & ODF support — DOCM, DOTM, DOTX, POTM, POTX, PPSM, PPSX, PPTM, XLSM, XLTM, XLTX, ODG, OTG, OTP, OTS, OTT, VSDX
• MIME group filtering — New FileTypeMIMEGroup enum lets you limit detection to a specific MIME major type (image, audio, video, etc.) via detect(in:matching:) and related APIs
• Full-file detection — Detect file types via FileHandle and URL APIs for formats that need more than a prefix

Improvements

• Rewritten ZIP-based detection — Parses central directory and inflates compressed entries for reliable Office/ODF identification
• Proper TIFF tag detection — ARW, CR2, NEF, and DNG detected via TIFF tag parsing instead of heuristics
• Better tar validation — Checksum-based tar detection
• Improved MPEG matching — More accurate MPEG header detection with ID3 header stripping
• Sendable conformances — All public types conform to Sendable
• New query APIs — dataRequirement(for:), minimumPrefixBytes(for:), canonicalFileExtension

Fixes

• Registry files with LF line endings — .reg detection now accepts both LF and CRLF line endings
• 64-bit integer helpers — Fixed to correctly read all 8 bytes
• Corrupt MKV handling — Graceful handling of malformed MKV files
