qz change log

• 1996-10-14 2.0.3a2 James Cherry reports that the -a option doesn't work. D'oh! Guess I should have tested it.
• 1996-09-21 2.0.3a1 Steven Alexander reports that DOS machines can't handle temporary filenames that look like file.qz.new, so they will now just be file.new.
• 1996-09-15 2.0.3a0 Typing ';exit' will call final cleanup code before exiting. (This to help users who may not be able to send a ^D to do the same thing.)
• 1996-09-04 2.0.2a1 Notes with
  or

  embedded in them now translate these to newlines on display when the note is displayed after an interactive addition, not just after an answer.

• 1996-08-14 2.0.2a0 Notes with
  or

  embedded in them now translate these to newlines on display.

• 1996-07-31 2.0.1a0 Oldest solution time (reported first in 2.0.0a11) now works correctly. Since this was actually a new feature, I'm bumping the version number.
• 1996-07-31 2.0.0a12 The algorithm error mentioned at a11 has now been fixed, which noticeably improves loading speed of large data sets. The old code built a search tree in O(n lg n) time, the new one does it in O(n).
• 1996-07-30 2.0.0a11 Quiz-end report now lists oldest solution time, so that you can be sure that you have worked through an entire set. I've just noticed an algorithm error that is slowing down loading of large data sets, but don't have time to fix it at the moment. It'll be the next thing I do, though.
• 1996-07-30 2.0.0a10 -p oldest wasn't working correctly under some circumstances, but has been fixed.
• 1996-07-29 2.0.0a9 Macintosh filename-embedded "command line arguments" were not being parsed correctly. That's fixed now.
• 1996-07-29 2.0.0a8 -p oldest wasn't updating internal data structures properly when more than one question had the same timestamp. This version fixes this problem.
• 1999-11-19 3.0.4 Major new release, not heavily tested. Changed just not to avoid using SIGTSTP under Windows.
• 2000 3.0.5 Undocumented changes.
• 2000 3.0.6 Undocumented changes.
• 2000 3.0.7 You can now quiz yourself on folders/directories full of quiz files.
• 2001 3.0.8 Fixed a statistical report formatting bug.
• 2001-11-27 3.0.9 Report the former age of questions when answered correctly.
• 2008-07-01 3.0.14 Question and answer regexp filters.
• 2008-09-04 3.0.15 Corrected final stats when filters in effect.
• 2010-04-20 3.0.16 You can display final stats while running a quiz by entering ";S".
