- split Tangram.pm into several modules
- replaced @ISA with 'use base'
- replaced default typetags with automounting
- prefetch now takes either class or remote

*::prefetch still need real-life testing,
especially when class(coll) <> class(item)
1.00 Nov 07 1999 - first mature release version
- deploy() now also works directly on DBI handles
- deploy() allows specification of SQL types via the schema hash

- temporarily removed RawDate and RawTime tests because M$ SQL
cannot handle them; those modules are still present though
1.04 Jan 03 2000 - interim version
- fixed two bugs related to explicit tables
1.05 Jan 03 2000 - interim version

- started cleaning up autovivification of colls upon save
- documented like()
- documented extended select options retrieve, order & filter
- changed _limit into the Limit in test suite
- added temporary hack in Makefile.PL to support Access

- fixed Array problem when removing elements from middle of collection
- (?)
1.10 Apr 19 2000 - interim version
- changed reset() into unload() and added support for partial unloading
- tx_do() can now propagate arguments to closure/anon-sub;
insert(), update() and erase() pass anon-subs to tx_do to prevent
leaks (thanks Radu Greab)
1.11 May 29 2000 - public version
- ordering result set by descending order is now supported
- die() on attempt to load from an invalid id
