Version 1.0.4
ui.link{...} with POST target can now be parameterized with BOTH content and text to allow HTML content for JavaScript browsers and a text-only version for accessiblity
Changes related to database selectors:
- Support for row-based locking
- New method :count(), caching and returning the number of rows, which WOULD have been returned by :exec()
- Bugfix: WHERE and HAVING expressions are now enclosed in parenthesis to avoid problems with operator precedence
ui.script{...} now supports external .js files
Changes in langtool.lua to cope with escaped new-line chars (\n)
