Appendix A. History

Here are a few key events in the development of this book, starting from most recent events:

2001-01-01 David A. Wheeler: Version 2.70 released, adding a significant amount of additional material, such as a significant expansion of the discussion of cross-site malicious content, HTML/URI filtering, and handling temporary files.
2000-05-24 David A. Wheeler: Switched to GNU's GFDL license, added more content.
2000-04-21 David A. Wheeler: Version 2.00 released, dated 21 April 2000, which switching the document's internal format from the Linuxdoc DTD to the DocBook DTD. Thanks to Jorge Godoy for helping me perform the transition.
2000-04-04 David A. Wheeler: Version 1.60 released; changed so that it now covers both Linux and Unix. Since most of the guidelines covered both, and many/most app developers want their apps to run on both, it made sense to cover both.
2000-02-09 David A. Wheeler: Noted that the document is now part of the Linux Documentation Project (LDP).
1999-11-29 David A. Wheeler: Initial version (1.0) completed and released to the public.
