Hi all,

- incremental search Ctrl+E
- usage counts for files
  (that means, .lpi files will forget unused files after a while)
- .lpi files do not any longer save default values
- publish project dialog
- code completion now copies calling conventions
  'cdecl' and 'inline'
- Find&Replace now supports a lot of regular expressions
  (very similar to perl).
  Replace now supports substitution variables like $1, $12, ${2}
- basic identifier completion  Ctrl+Space
- TListBox.TopIndex
- TButton.Default
- IDE Windows menu
