Notes

Experiment: Pre-Compiled Native Linux Gems

With the v1.11.0 release candidates, we are experimenting with shipping pre-compiled native Linux gems for the x86-linux and x86_64-linux platforms.

If this works properly for you, it will speed up installation time on Linux.

If this doesn't work for you, please drop us a note at #1983, we may reach out to you for more information on your distro and configuration.

Either way, we'd appreciate some feedback at #1983.

Dependencies

This release introduces support for:

• Ruby 2.7, including the precompiled native binary gems for Windows.

This release ends support for:

• Ruby 2.3, for which official support ended on 2019-03-31 [#1886] (Thanks @ashmaroli!)
• JRuby 9.1, which is the Ruby 2.3-compatible release.

Added

• Add support for CSS queries "a:has(> b)", "a:has(~ b)", and "a:has(+ b)". [#688] (Thanks, @jonathanhefner!)
• Add Node#value? to better match expected semantics of a Hash-like object. [#1838, #1840] (Thanks, @MatzFan!)
• [MRI] Add Nokogiri::XML::Node#line= for use by downstream libs like nokogumbo. [#1918] (Thanks, @stevecheckoway!)

Improved

• Add frozen_string_literal: true magic comment to all lib files. [#1745] (Thanks, @oniofchaos!)
• Improve performance of some namespace operations. [#1916] (Thanks, @ashmaroli!)
• Remove unnecessary array allocations from Node serialization methods [#1911] (Thanks, @ashmaroli!)
• Avoid creation of unnecessary zero-length String objects. [#1970] (Thanks, @ashmaroli!)
• [JRuby] Lots of code cleanup and performance improvements. [#1934] (Thanks, @kares!)

Fixed

• [JRuby] Standardize reading from IO like objects, including StringIO. [#1888, #1897]
• [JRuby] Change NodeSet#to_a to return a RubyArray instead of Object, for compilation under JRuby 9.2.9 and later. [#1968, #1969] (Thanks, @headius!)

Changed

VersionInfo and the output of nokogiri -v

This release changes the information provided in
Nokogiri::VersionInfo, see #1482 and #1974 for background. Note that
the output of nokogiri -v will also reflect these changes.

Nokogiri::VersionInfo will no longer contain the following keys (previously these were set only when vendored libraries were being used)

• libxml/libxml2_path
• libxml/libxslt_path

Nokogiri::VersionInfo now contains version metadata for libxslt:

• libxslt/source (either "packaged" or "system", similar to libxml/source)
• libxslt/compiled (the version of libxslt compiled at installation time, similar to libxml/compiled)
• libxslt/loaded (the version of libxslt loaded at runtime, similar to libxml/loaded)
• libxslt/patches moved from libxml/libxslt_patches

Nokogiri::VersionInfo key libxml/libxml2_patches has been renamed to libxml/patches

These C macros will no longer be defined:

• NOKOGIRI_LIBXML2_PATH
• NOKOGIRI_LIBXSLT_PATH

These global variables will no longer be defined:

• NOKOGIRI_LIBXML2_PATH
• NOKOGIRI_LIBXSLT_PATH

These constants have been renamed:

• Nokogiri::LIBXML_VERSION is now Nokogiri::LIBXML_COMPILED_VERSION
• Nokogiri::LIBXML_PARSER_VERSION is now Nokogiri::LIBXML_LOADED_VERSION

These methods have been renamed and the return type changed from String to Gem::Version:

• VersionInfo#loaded_parser_version is now #loaded_libxml_version
• VersionInfo#compiled_parser_version is now #compiled_libxml_version

Nokogiri.uses_libxml? now accepts an optional requirement string which is interpreted as a Gem::Requirement and tested against the loaded libxml2 version (the value in VersionInfo key libxml/loaded). This greatly simplifies much of the version-dependent branching logic in both the implementation and the tests.

To sum these changes up, the output from CRuby when using vendored libraries was something like:
