From jEdit 4.2 to 4.4

  1. All regular expressions in mode files were rewritten to use java.util.regex instead of gnu.regexp.

  2. HASH_CHAR handling of xxx_REGEXP elements has been updated, as explained in the section called “The SPAN_REGEXP Tag”.

  3. The EXCLUDE_MATCH attribute got superseded by MATCH_TYPE. The attribute values translate from TRUE to CONTEXT and from FALSE to RULE, respectively. For more information see the section called “The MATCH_TYPE Attribute”.

  4. NO_ESCAPE is now deprecated and ignored by the parsing engine. ESCAPE is now a valid attribute for SPAN and SPAN_REGEXP rules.
