iG:Syntax Hiliter v4.2 is now available for download. Some bugs have been fixed in v4.1 and v4.2 along with a few new additions and improvements, some of which are:
- Additional language files can be put in “geshi” folder inside current theme so that the files won’t get overwritten on plugin upgrade
- Github Gist embed XSS bug fixed
- Shorthand tags for all languages are now supported
- A code block is parsed only once, subsequent similar code blocks in same post/page use the same output, for better performance
A more detailed changelog is available here.
