1.14.0.rc1 / 2022-12-29

1.14.0.rc1 / 2022-12-29

This is a prerelease.

• Please provide feedback on it at #2747
• Full details on this release are at https://github.com/sparklemotion/nokogiri/blob/main/CHANGELOG.md

Notable changes:

• Introduces native gem support for Ruby 3.2.
• Ends support for Ruby 2.6 and JRuby 9.3
• Official native gem support for aarch64-linux
• Experimental native gem support for arm-linux
• Pattern matching API

Please note that Ruby 3.2 changes how symbols are resolved on MacOS, so we're particularly interested in hearing feedback from MacOS users about the native (precompiled) gem packages for Ruby 3.2.

We're waiting for the following to do a final release:

• a final release of rake-compiler-dock that supports Ruby 3.2
• Windows CI environment that runs Ruby 3.2.0, and green tests
• feedback to build confidence that our approach to Darwin symbol resolution in the precompiled extension works for everyone

1.13.10 / 2022-12-07

Security

• [CRuby] Address CVE-2022-23476, unchecked return value from xmlTextReaderExpand. See GHSA-qv4q-mr5r-qprj for more information.

Improvements

• [CRuby] XML::Reader#attribute_hash now returns nil on parse errors. This restores the behavior of #attributes from v1.13.7 and earlier. [#2715]

1.13.9 / 2022-10-18

1.13.9 / 2022-10-18

Security

• [CRuby] Vendored libxml2 is updated to address CVE-2022-2309, CVE-2022-40304, and CVE-2022-40303. See GHSA-2qc6-mcvw-92cw for more information.
• [CRuby] Vendored zlib is updated to address CVE-2022-37434. Nokogiri was not affected by this vulnerability, but this version of zlib was being flagged up by some vulnerability scanners, see #2626 for more information.

Dependencies

• [CRuby] Vendored libxml2 is updated to v2.10.3 from v2.9.14.
• [CRuby] Vendored libxslt is updated to v1.1.37 from v1.1.35.
• [CRuby] Vendored zlib is updated from 1.2.12 to 1.2.13. (See LICENSE-DEPENDENCIES.md for details on which packages redistribute this library.)

Fixed

• [CRuby] Nokogiri::XML::Namespace objects, when compacted, update their internal struct's reference to the Ruby object wrapper. Previously, with GC compaction enabled, a segmentation fault was possible after compaction was triggered. [#2658] (Thanks, @eightbitraptor and @peterzhu2118!)
• [CRuby] Document#remove_namespaces! now defers freeing the underlying xmlNs struct until the Document is GCed. Previously, maintaining a reference to a Namespace object that was removed in this way could lead to a segfault. [#2658]

1.13.8 / 2022-07-23

1.13.8 / 2022-07-23

Deprecated

• XML::Reader#attribute_nodes is deprecated due to incompatibility between libxml2's xmlReader memory semantics and Ruby's garbage collector. Although this method continues to exist for backwards compatibility, it is unsafe to call and may segfault. This method will be removed in a future version of Nokogiri, and callers should use #attribute_hash instead. [#2598]

Improvements

• XML::Reader#attribute_hash is a new method to safely retrieve the attributes of a node from XML::Reader. [#2598, #2599]

Fixed

• [CRuby] Calling XML::Reader#attributes is now safe to call. In Nokogiri <= 1.13.7 this method may segfault. [#2598, #2599]

1.13.5 / 2022-05-04

Security

• [CRuby] Vendored libxml2 is updated to address CVE-2022-29824. See GHSA-cgx6-hpwq-fhv5 for more information.

Dependencies

• [CRuby] Vendored libxml2 is updated from v2.9.13 to v2.9.14.

Improvements

• [CRuby] The libxml2 HTML4 parser no longer exhibits quadratic behavior when recovering some broken markup related to start-of-tag and bare < characters.

Changed

• [CRuby] The libxml2 HTML4 parser in v2.9.14 recovers from some broken markup differently. Notably, the XML CDATA escape sequence <![CDATA[ and incorrectly-opened comments will result in HTML text nodes starting with <! instead of skipping the invalid tag. This behavior is a direct result of the quadratic-behavior fix noted above. The behavior of downstream sanitizers relying on this behavior will also change. Some tests describing the changed behavior are in test/html4/test_comments.rb.

1.13.3 / 2022-02-21

Fixed

• [CRuby] Revert a HTML4 parser bug in libxml 2.9.13 (introduced in Nokogiri v1.13.2). The bug causes libxml2's HTML4 parser to fail to recover when encountering a bare < character in some contexts. This version of Nokogiri restores the earlier behavior, which is to recover from the parse error and treat the < as normal character data (which will be serialized as < in a text node). The bug (and the fix) is only relevant when the RECOVER parse option is set, as it is by default. [#2461]
