New Features in 5.2

 - Added built-in patterns for CSS, XML, and regular expressions (Regex).
   Many other pattern updates.

 - Support for high- and true-color systems.  NEdit now will automatically
   select the best visual from your X server.  This reduces the chance of
   running out of colors.

 - New features in the Find and Replace dialogs:

   o Replacement across multiple windows in a session.
   o Case sensitivity may be set independently of regular expressions.
   o Add "Replace and Find" command, which saves keystrokes when doing
     a large-scale find & replace.

 - ClearCase version-extended pathnames.

 - Many new macro subroutines and variables.

 - Array support in macros.

 - Range highlighting of matching delimiters.

 - Undo and Redo highlights the text that has changed, when visible.

 - Support for wheel mouse scrolling on servers that support it (XFree86).

 - Improved accelerator key handling.

 - Insert Control Code dialog accepts value in any valid C notation

 - Optional beeping when search operations wrap.

 - Additional default search styles.

 - Optional displaying of path names in the window list menu.


Bug Fixes in 5.2

 - Fix a crash when entering an invalid line number in "Goto Line".

 - Ignore the Caps-Lock key when invoking accelerators.

 - Fix problems when running NEdit on 64-bit platforms like Alpha

 - NEdit failed to open files if some directories above were not "readable"

 - Fix potential crashes if some system calls fail

 - When no colors are left, attempt to reuse the closest matching color.  This
   allows NEdit's syntax highlighting to better coexist with Netscape, which
   unfortuntely takes all available colors.

 - "Overtype" mode is now bound to the Insert key, to be consistent with
   Motif text fields.

 - Accelerators now available in confirmation dialogs, and may be invoked
   without the Alt key.

 - Fix a couple of memory corruption problems


New Features in 5.1

   below.

   loading of tag files, and automatic reload of modified tag files.

 - NEdit can now read and write MS DOS format files.

 - New built-in syntax highlighting patterns for Lex, PostScript, SQL,
   Many syntax highlighting pattern improvements.

 - Optional warnings about external modifications to files

 - Clearcase awareness

 - Session manager restart capability

 - Default language mode "*" for user-defined menu items, allows
   per-language variations on a common base

   accelerators
