Updates bleach from 6.2.0 to 6.4.0

Changelog

Sourced from bleach's changelog.

Version 6.4.0 (June 5th, 2026)

NOTE: 2026-06-05: Bleach is no longer maintained. There will be no future releases including for security issues. See issue: <https://github.com/mozilla/bleach/issues/698>__

Backwards incompatible changes

• Dropped support for pypy 3.10. (#764)

Security fixes

• Fix bug 2023812 / GHSA-8rfp-98v4-mmr6.

  Fix XSS issue with sanitize_uri_value where disallowed schemes with Unicode invisible characters wouldn't be rejected.

  For example::

  import bleach payload1 = 'Click' result1 = bleach.clean(payload1) print(repr(result1))

  outputs::

  'Click'

  See the advisory for details.

• Fix GHSA-gj48-438w-jh9v.

  Fix issue where URI sanitization wasn't happening in formaction attributes.

  See the advisory for details.

Bug fixes

• Add support for pypy 3.11. (#764)

• Drop version max in tinycss2 pin. (#772)

  This removes one of the things we had to keep checking and updating. Users now own the responsibility for correctness with the version of tinycss2 they're using.

Version 6.3.0 (October 27th, 2025)

Updates fonttools from 4.56.0 to 4.60.2

Release notes

Sourced from fonttools's releases.

4.60.2

• Backport release Same as 4.61.0 but without "Drop support for EOL Python 3.9" change to allow downstream projects still on Python 3.9 to avail of the security fix for CVE-2025-66034 (#3994, #3999).

4.60.1

• [ufoLib] Reverted accidental method name change in UFOReader.getKerningGroupConversionRenameMaps that broke compatibility with downstream projects like defcon (#3948, #3947, robotools/defcon#478).
• [ufoLib] Added test coverage for getKerningGroupConversionRenameMaps method (#3950).
• [subset] Don't try to subset BASE table; pass it through by default instead (#3949).
• [subset] Remove empty BaseRecord entries in MarkBasePos lookups (#3897, #3892).
• [subset] Add pruning for MarkLigPos and MarkMarkPos lookups (#3946).
• [subset] Remove duplicate features when subsetting (#3945).
• [Docs] Added documentation for the visitor module (#3944).

4.60.0

• [pointPen] Allow reverseFlipped parameter of DecomposingPointPen to take a ReverseFlipped enum value to control whether/how to reverse contour direction of flipped components, in addition to the existing True/False. This allows to set ReverseFlipped.ON_CURVE_FIRST to ensure that the decomposed outline starts with an on-curve point before being reversed, for better consistency with other segment-oriented contour transformations. The change is backward compatible, and the default behavior hasn't changed (#3934).

• [filterPen] Added ContourFilterPointPen, base pen for buffered contour operations, and OnCurveStartPointPen filter to ensure contours start with an on-curve point (#3934).

• [cu2qu] Fixed difference in cython vs pure-python complex division by real number (#3930).

• [varLib.avar] Refactored and added some new sub-modules and scripts (#3926).

  • varLib.avar.build module to build avar (and a missing fvar) binaries into a possibly empty TTFont,
  • varLib.avar.unbuild module to print a .designspace snippet that would generate the same avar binary,
  • varLib.avar.map module to take TTFont and do the mapping, in user/normalized space,
  • varLib.avar.plan module moved from varLib.avarPlanner.

  The bare fonttools varLib.avar script is deprecated, in favour of fonttools varLib.avar.build (or unbuild).

• [interpolatable] Clarify linear_sum_assignment backend options and minimal dependency usage (#3927).

• [post] Speed up build_psNameMapping (#3923).

• [ufoLib] Added typing annotations to fontTools.ufoLib (#3875).

4.59.2

• [varLib] Clear USE_MY_METRICS component flags when inconsistent across masters (#3912).
• [varLib.instancer] Avoid negative advance width/height values when instatiating HVAR/VVAR, (unlikely in well-behaved fonts) (#3918).
• [subset] Fix shaping behaviour when pruning empty mark sets (#3915, harfbuzz/harfbuzz#5499).
• [cu2qu] Fixed dot() product of perpendicular vectors not always returning exactly 0.0 in all Python implementations (#3911)
• [varLib.instancer] Implemented fully-instantiating avar2 fonts (#3909).
• [feaLib] Allow float values in VariableScalar's axis locations (#3906, #3907).
• [cu2qu] Handle special case in calc_intersect for degenerate cubic curves where 3 to 4 control points are equal (#3904).

4.59.1

• [featureVars] Update OS/2.usMaxContext if possible after addFeatureVariationsRaw (#3894).
• [vhmtx] raise TTLibError('not enough data...') when hmtx/vmtx are truncated (#3843, #3901).
• [feaLib] Combine duplicate features that have the same set of lookups regardless of the order in which those lookups are added to the feature (#3895).
• [varLib] Deprecate varLib.mutator in favor of varLib.instancer. The latter provides equivalent full (static font) instancing in addition to partial VF instancing.
  CLI users should replace fonttools varLib.mutator with fonttools varLib.instancer. API users should migrate to fontTools.varLib.instancer.instantiateVariableFont (#2680).

4.59.0

• Removed hard-dependency on pyfilesystem2 (fs package) from fonttools[ufo] extra. This is replaced by the fontTools.misc.filesystem package, a stdlib-only, drop-in replacement for the subset of the pyfilesystem2's API used by fontTools.ufoLib. The latter should continue to work with the upstream fs (we even test with/without). However, clients who wish to continue using fs can do so by depending on it directly instead of via the fonttools[ufo] extra (#3885, #3620).
• [xmlWriter] Replace illegal XML characters (e.g. control or non-characters) with "?" when dumping to ttx (#3868, #71).
• [varLib.hvar] Fixed vertical metrics fields copy/pasta error (#3884).
• Micro optimizations in ttLib and sstruct modules (#3878, #3879).
• [unicodedata] Add Garay script to RTL_SCRIPTS (#3882).

4.61.0 (released 2025-11-28)

• [varLib.main]: SECURITY Only use basename(vf.filename) to prevent path traversal attacks when running fonttools varLib command, or code which invokes fonttools.varLib.main(). Fixes CVE-2025-66034, see: GHSA-768j-98cg-p3fv.

Updates idna from 3.10 to 3.15

Changelog

Sourced from idna's changelog.

3.15 (2026-05-12)

• Enforce DNS-length cap on individual labels early in check_label, short-circuiting contextual-rule processing for oversized input while staying compatible with UTS 46 usage.
• Tidy core helpers: hoist bidi category sets to module-level frozensets (avoiding per-codepoint list construction), simplify length checks, and reuse the shared _unicode_dots_re from idna.core in the codec module.
• Use raise ... from err for proper exception chaining and switch internal string formatting to f-strings.
• Allow flit_core 4.x in the build backend.
• Expand the ruff lint set (flake8-bugbear, flake8-simplify, pyupgrade, perflint) and apply the surfaced fixes; pin lint CI to Python 3.14.
• Add Dependabot configuration for GitHub Actions.
• Convert README and HISTORY from reStructuredText to Markdown.
• Reference CVE-2026-45409 for the 3.14 advisory in place of the initial GHSA identifier.

Thanks to Felix Yan, Stan Ulbrych, and metsw24-max for contributions to this release.

3.14 (2026-05-10)

• Removed opportunity to process long inputs into quadratic time by rejecting oversize inputs up-front. Closes a bypass of the CVE-2024-3651 mitigation. [CVE-2026-45409]

Thanks to Stan Ulbrych for reporting the issue.

3.13 (2026-04-22)

• Correct classification error for codepoint U+A7F1

3.12 (2026-04-21)

• Update to Unicode 17.0.0.
• Issue a deprecation warning for the transitional argument.
• Added lazy-loading to provide some performance improvements.
• Removed vestiges of code related to Python 2 support, including segmentation of data structures specific to Jython.

Thanks to Rodrigo Nogueira for contributions to this release.

3.11 (2025-10-12)

• Update to Unicode 16.0.0, including significant changes to UTS46 processing. As a result of Unicode ending support for it, transitional processing no longer has an effect and returns the same result.
