thanks to Jerry D. Hedden and Michael G Schwern.
Fixed DBI for VMS thanks to Peter (Stig) Edwards.
Added client-side caching to DBD::Gofer. Can use any cache with
get($k)/set($k,$v) methods, including all the Cache and Cache::Cache
distribution modules plus Cache::Memcached, Cache::FastMmap etc.
Works for all transports. Overridable per handle.
Added DBI::Util::CacheMemory for use with DBD::Gofer caching.
It's a very fast and small strict subset of Cache::Memory.
1.59 - 2007-08-23, Tim Bunce (svn r9874)

1.57 - 2007-06-13, Tim Bunce (svn r9639)
Note: this release includes a change to the DBI::hash() function which will
now produce different values than before *if* your perl was built with 64-bit
'int' type (i.e. "perl -V:intsize" says intsize='8'). It's relatively rare
for perl to be configured that way, even on 64-bit systems.
Fixed XS versions of select*_*() methods to call execute()
fetch() etc., with inner handle instead of outer.
Fixed execute_for_fetch() to not cache errstr values
thanks to Bart Degryse.
Fixed unused var compiler warning thanks to JDHEDDEN.
Fixed t/86gofer_fail tests to be less likely to fail falsely.
Changed DBI::hash to return 'I32' type instead of 'int' so results are
portable/consistent regardless of size of the int type.
Corrected timeout example in docs thanks to Egmont Koblinger.
Changed t/01basic.t to warn instead of failing when it detects
a problem with Math::BigInt (some recent versions had problems).
Added support for !Time and !Time~N to DBI::Profile Path. See docs.

Added non-random (deterministic) mode to DBI_GOFER_RANDOM mechanism.

DBI::ProfileDumper changes:
Don't write file if there's no profile data.
Uses full natural precision when saving data (was using %.6f)
Optimized flush_to_disk().
Locks the data file while writing.
Enabled filename to be a code ref for dynamic names.
DBI::ProfileDumper::Apache changes:
Added Quiet=>1 to avoid write to STDERR in flush_to_disk().
Added Dir=>... to specify a writable destination directory.
Enabled DBI_PROFILE_APACHE_LOG_DIR for mod_perl 1 as well as 2.
Added parent pid to default data file name.

so now in html you get links to individual methods etc.
Changed default gofer retry_limit from 2 to 0.
Changed tests to workaround Math::BigInt broken versions.
Changed dbi_profile_merge() to dbi_profile_merge_nodes()
old name still works as an alias for the new one.
Removed old DBI internal sanity check that's no longer valid
causing "panic: DESTROY (dbih_clearcom)" when tracing enabled
Added DBI_GOFER_RANDOM env var that can be use to trigger random
failures and delays when executing gofer requests. Designed to help
test automatic retry on failures and timeout handling.
Added lots more docs to all the DBD::Gofer and DBI::Gofer classes.
1.55 - 2007-05-04, Tim Bunce (svn r9504)
Fixed set_err() so HandleSetErr hook is executed reliably, if set.
Fixed accuracy of profiling when perl configured to use long doubles.
Fixed 42prof_data.t on fast systems with poor timers thanks to Malcolm Nooning.
Fixed potential corruption in selectall_arrayref and selectrow_arrayref
for compiled drivers, thanks to Rob Davies.
Rebuild your compiled drivers after installing DBI.
Changed some handle creation code from perl to C code,
to reduce handle creation cost by ~20%.
Changed internal implementation of the CachedKids attribute
so it's a normal handle attribute (and initially undef).
Changed connect_cached and prepare_cached to avoid a FETCH method call,
and thereby reduced cost by ~5% and ~30% respectively.
Changed _set_fbav to not croak when given a wrongly sized array,
it now warns and adjusts the row buffer to match.
Changed some internals to improve performance with threaded perls.
Changed DBD::NullP to be slightly more useful for testing.

the method won't be called. A callback for "*" is applied to all methods
that don't have their own callback.
Added $h->{ReadOnly} attribute.
Added support for DBI Profile Path to contain refs to scalars
which will be de-ref'd for each profile sample.
Added dbilogstrip utility to edit DBI logs for diff'ing (gets installed)

Added take_imp_data() to DBI::PurePerl.
Gofer related changes:
Fixed gofer pipeone & stream transports to avoid risk of hanging.
Improved error handling and tracing significantly.
Added way to generate random 1-in-N failures for methods.
Added automatic retry-on-error mechanism to gofer transport base class.
Added tests to show automatic retry mechanism works a treat!
Added go_retry_hook callback hook so apps can fine-tune retry behaviour.
Added header to request and response packets for sanity checking
and to enable version skew between client and server.
Added forced_single_resultset, max_cached_sth_per_dbh and max_cached_dbh_per_drh
to gofer executor config.
Driver-private methods installed with install_method are now proxied.
No longer does a round-trip to the server for methods it knows
have not been overridden by the remote driver.
Most significant aspects of gofer behaviour are controlled by policy mechanism.
Added policy-controlled caching of results for some methods, such as schema metadata.
The connect_cached and prepare_cached methods cache on client and server.
The bind_param_array and execute_array methods are now supported.
Worked around a DBD::Sybase bind_param bug (which is fixed in DBD::Sybase 1.07)
Added goferperf.pl utility (doesn't get installed).
Many other assorted Gofer related bug fixes, enhancements and docs.
The http and mod_perl transports have been remove to their own distribution.
Client and server will need upgrading together for this release.
1.54 - 2007-02-23, Tim Bunce (svn r9157)
NOTE: This release includes the 'next big thing': DBD::Gofer.
Take a look!
WARNING: This version has some subtle changes in DBI internals.
It's possible, though doubtful, that some may affect your code.
I recommend some extra testing before using this release.
Or perhaps I'm just being over cautious...

Changed DBI::PurePerl trace() method to be more consistent.
Changed set_err method to effectively not append to errstr if the new errstr
is the same as the current one.
Changed handle factory methods, like connect, prepare, and table_info,
to copy any error/warn/info state of the handle being returned
up into the handle the method was called on.
Changed row buffer handling to not alter NUM_OF_FIELDS if it's
inconsistent with number of elements in row buffer array.
Updated DBI::DBD docs re handling multiple result sets.
