General:

Removed the textured background. Too many people complained that it made reading the pages uncomfortable.

8 August 1996:

General:

Coming back from holidays, I found my mail box filled with about 45 messages concerning the Bug Lists. Most of them new bug reports and a few new offers from people to help me. Bug reporters: Please understand that I can not reply to every message. Just wait for 'your bug' to appear in the list.
Been working on organizing things so that the people who want to help me with the bug lists can download 'unfinished bug reports'.

Delphi 2.0:

Borland has released a new version, Delphi 2.01 (11 June), which has some bugs fixed (people, help me to find which bugs are fixed) and some extra stuff, mostly WWW/Internet related if I understand it correctly. I don't have the patch yet, myself.
Some compiler bugs that have been fixed have already been removed from the Bug List pages:
- The first optimizer error
- The shortstring copy bug
- The compiler crash with Optimization and Range checking on
- The linker bug that resulted in "overflow in arithmetic conversion"
A new compiler bug was found and added to the list ("optimizer still produces bad code")

Two people have volunteered until now to help me with maintaining the Bug List: Brad Stowers and Sandro Stefano Fernandes
