Revision history for Perl extension Parse::Win32Registry.

** 0.21 2006-07-30

Checks added after every sysread, and an attempt made to improve the
error messages presented. Internal error messages have been made
distinct from errors generated when parsing invalid data.

The code that looks up the RGDB entry for Win95 keys has been revised
to remove some duplicate code. It's still too long.

The use of substr and unpack when parsing new NT keys and values
has been reduced.

Reading REG_DWORD values which are not the expected four bytes in
length no longer results in an exception. Similarly, get_data now
returns undef for these values instead of failing.

get_data_as_string updated to return (no data) when get_data returns
an empty string, and (invalid data) when get_data returns undef (which
should only occur for invalid REG_DWORD values).

The undocumented print_debug methods have been updated and added to.
Win95 keys and values could already dump their on-disk structures; now
WinNT keys and values can dump their on-disk structures, and WinNT
keys can dump their offset lists.

Registry files are now opened using the three-argument version of open.
