=head2 Changes in DBI 1.29, 15th July 2002
NOTE: This release changes the specified behaviour for the
: fetchrow_array method when called in a scalar context:
: The DBI spec used to say that it would return the FIRST field.
: Which field it returns (i.e., the first or the last) is now undefined.
: This does not affect statements that only select one column, which is
: usually the case when fetchrow_array is called in a scalar context.
: FYI, this change was triggered by discovering that the fetchrow_array
: implementation in Driver.xst (used by most compiled drivers)
: didn't match the DBI specification. Rather than change the code
: to match, and risk breaking existing applications, I've changed the
: specification (that part was always of dubious value anyway).
NOTE: Future versions of the DBI may not support for perl 5.5 much longer.
: If you are still using perl 5.005_03 you should be making plans to
: upgrade to at least perl 5.6.1, or 5.8.0. Perl 5.8.0 is due to be
: released in the next week or so. (Although it's a "point 0" release,
: it is the most throughly tested release ever.)
Added XS/C implementations of selectrow_array, selectrow_arrayref, and
selectall_arrayref to Driver.xst. See DBI 1.26 Changes for more info.
Removed support for the old (fatally flawed) "5005" threading model.
Added support for new perl 5.8 iThreads thanks to Gerald Richter.
(Threading support and safety should still be regarded as beta
quality until further notice. But it's much better than it was.)
Updated the "Threads and Thread Safety" section of the docs.
The trace output can be sent to STDOUT instead of STDERR by using
"STDOUT" as the name of the file, i.e., $h->trace(..., "STDOUT")
Added pointer to perlreftut, perldsc, perllol, and perlboot manuals
into the intro section of the docs, suggested by Brian McCain.
Fixed DBI::Const::GetInfo::* pod docs thanks to Zack Weinberg.
Some changes to how $dbh method calls are treated by DBI::Profile:
Meta-data methods now clear $dbh->{Statement} on entry.
Some $dbh methods are now profiled as if $dbh->{Statement} was empty
(because thet're unlikely to actually relate to its contents).
Updated dbiport.h to ppport.h from perl 5.8.0.
Tested with perl 5.5.3 (vanilla, Solaris), 5.6.1 (vanilla, Solaris), and
perl 5.8.0 (RC3@17527 with iThreads & Multiplicity on Solaris and FreeBSD).

Enjoy!
