0.21.0

[0.21.0] - 2026-08-13

✨ Added

• Built-in MIME type exclusion list (#98, 416ee17, #100, f761b4b)
  • The extension now ships a built-in list of non-compressible MIME types (video/, audio/, common image/font/archive formats), consulted whenever brotli.output_compression_exclude_types doesn't produce a definitive match
  • The list is shown in the phpinfo() output
  • Regression tests tests/ob_exclude_004.phpt (wildcard match) and renamed tests/ob_exclude_001.phpt to reflect it exercises the built-in list without any ini setting
• Negation tokens in brotli.output_compression_exclude_types (#102)
  • A token prefixed with ! re-enables compression for a MIME type that would otherwise be excluded by the built-in list, supporting exact matches and type/* wildcards
  • Within the same list, when multiple tokens match a MIME type, the last one wins regardless of sign (gitignore-style precedence), e.g. image/*,!image/png excludes all images except PNG
  • Regression tests tests/ob_exclude_005.phpt–tests/ob_exclude_008.phpt
• phpinfo() improvements (#99)
  • Show whether the bundled or an external Brotli library is in use
  • Show whether the brotli APCu serializer is active, inactive, or APCu isn't loaded
  • Rename "APCu serializer ABI" to "APCu serializer interface version", and show when APCu support wasn't built in

🐛 Fixed

• Memory leak when BrotliEncoderCompressStream() fails on PHP 7.4+ (#95, b222289)
  • The early-return path taken on PHP_VERSION_ID >= 70400 didn't free output, unlike the other path
• Compiler warnings (#96, 1618491, dc4e1e5)
  • Silence a -Wunicode warning from an unintended \U escape sequence
  • Remove unused zval *res locals in brotli_compress_add() and brotli_uncompress_add()

📈 Improved

• Deflake tests/streams_001.phpt, tests/streams_002.phpt and tests/streams_004.phpt by giving each its own scratch file instead of sharing tests/data.out (#101, 5d988e7)
  • PHP 8.6's parallel run-tests.php workers raced each other over the shared file, causing intermittent failures
