Many new syntax highlighting modes were added, and many existing ones were enhanced. jEdit now supports syntax highlighting for 133 languages.

The following new token types were added:

Any capture groups defined in the SPAN_REGEXP element's BEGIN child are now substituted into the END child for matching purposes. This allows here-docs in languages such as Perl to be highlighted correctly.

A new NO_ESCAPE attribute has been added to the SPAN and SPAN_REGEXP elements.

A new IMPORT rule causes the current ruleset to inherit the rules from the given ruleset.

A background color defined for a ruleset's default token type now takes effect on tokens that appear inside this ruleset for which no explicit background color is defined.
