1.69 - fixed a bug in push -- DB_APPEND wasn't working properly.
Fixed the R_SETCURSOR bug introduced in 1.68
Added a new Perl variable $DB_File::db_ver
-
-
-
+ 1.70 - Initialise $DB_File::db_ver and $DB_File::db_version with
+ GV_ADD|GV_ADDMULT -- bug spotted by Nick Ing-Simmons.
+ Added a BOOT check to test for equivalent versions of db.h &
+ libdb.a/so.
+ 1.71 - Support for Berkeley DB version 3.
+ Support for Berkeley DB 2/3's backward compatability mode.
+ Rewrote push
+ 1.72 - No change to DB_File.xs
+ 1.73 - No change to DB_File.xs
+ 1.74 - A call to open needed parenthesised to stop it clashing
+ with a win32 macro.
+ Added Perl core patches 7703 & 7801.
+ 1.75 - Fixed Perl core patch 7703.
+ Added suppport to allow DB_File to be built with
+ Berkeley DB 3.2 -- btree_compare, btree_prefix and hash_cb
+ needed to be changed.
+ 1.76 - No change to DB_File.xs
+ 1.77 - Tidied up a few types used in calling newSVpvn.
+ 1.78 - Core patch 10335, 10372, 10534, 10549, 11051 included.
+ 1.79 - NEXTKEY ignores the input key.
+ Added lots of casts
+ 1.800 - Moved backward compatability code into ppport.h.
+ Use the new constants code.
+ 1.801 - No change to DB_File.xs
