** 11-04-98 RELEASE 1.05

• Tweaks for MIN_PERL_DEFINE.
• Renamed tvseek.ch -> tvseek.h to avoid confusing dumb compilers.
• Switched tvgen.pl to use 'cp -f'.

** 07-11-98 RELEASE 1.04

• Tweaks to improve diagnostics.
• Fixed minor hiccups noticed by cpan-testers.
• tvgen.pl now checks modification times of tvcommon.[ch].

** 07-07-98 RELEASE 1.03

• Changed allocation macros to include the return value in deference to the C++ new operator.
• Tweaks to make TV_TEST work for more -Dmacro configurations.
• There are still REFCNT problems in the test suite. Just ignore the warnings. They are harmless.

** 03-04-98 RELEASE 1.02

• Fixed an obscure bug in the insertion algorithm. Tightened assertion constraints.

** 02-21-98 RELEASE 1.01

• Hide tv_testmalloc unless TV_TEST is defined.
• Migrated test scripts to the latest version of Test.pm.

** 02-08-98 RELEASE 1.00

• Clarified documentation. Bumped version number.

** 02-03-98 RELEASE 0.09

• Fixed a serious bug in seek (when unique=1). Expanded regression tests.
• Minor tweaks.

** 01-23-98 RELEASE 0.07

• Factored out code that isn't sensitive to key/data layout. Unfortunately, this change necessitated tweaking the memory layout.
• tc_insert has much better overall performance. tc_seek now does a full binary search. tc_delete is re-implemented with rotations. Asymptotic performance is now respectable.
• tv_compress, tv_balance added.
• memmove & memcpy of slots used throughout (instead of assignment). Added more hooks for C++. Fixed cpp (re)directives.

** EARLIER RELEASES

• Purified.
• Compiles with C++.
• Attempted to optimize the fill ratio. tc_insert version 0.01 only used about 35% of the available slots! After adding a bunch of kludges, I got it up to 65%. Hm. Need to re-think this.
• Tightened constraints for cursor boundry conditions.
