Changes in version 1.0 (2007-04-27)                   

    o   The 'DB' format has been removed; users should use 'DB1' instead

    o   Internals of 'DB1' format have changed so that it should be a bit
	more reliable but perhaps a little slower

    o   The 'dbDisconnect' generic has been removed since it is no longer
	necessary for the 'DB1' format (as it was before).  It was never
	needed for the 'RDS' format and one never existed for that format.

                  Changes in version 0.9 (2006-11-08)                   

    o   For 'filehashRDS' class, the 'dbDir' slot has been renamed to 'dir'.

    o   An attempt has been made to normalize the error handling to make it
	consistent.

    o   The various 'dump' functions have been given a 'type' argument

                  Changes in version 0.8 (2006-09-22)                   

    o   Added function dbLazyLoad for lazy loading filehash databases.

    o   dbCreate and dbInit are now generics with a method for character
	vectors.  The behavior should be the same as before, by default.

    o   dbLoad is generic.

    o   The second argument to dbMultiFetch is 'key', not 'keys'.

    o   dbInitialize is deprecated

    o   'DB1' and 'RDS' formats use normalizePath() for resolving paths to
	directories

    o   There is a vignette now [via vignette("filehash")]

                 Changes in version 0.6-3 (2006-06-01)                  

    o   Added methods for "[[", "$", "[[<-", and "$<-" for filehash
	objects. Only character indices are allowed

    o   filehash-DB functions use the new serialize() from R 2.4.0 so that
	numeric data will not suffer from rounding error due to previous use
	of serialize(ascii = TRUE).

    o   New format filehash-DB1 which stores the key index/map and data in a
	single file.

    o   New "filehash" method for lapply so that functions can be applied to
	database entries.

                 Changes in version 0.4-1 (2006-04-14)                  

    o   Patch release, changed some internals for the "DB" type databases

    o   Added test database for regression testing in future releases

                  Changes in version 0.4 (2006-02-07)                   

    o   Added name mangling scheme to prevent clobbering on case-insensitive
	OSes like Windows (thanks to Bill Venables and David Brahm)

    o   Added dumpImage, dumpObjects, dumpDF functions for dumping various
	things to filehash databases

    o   Added filehashOption() function for setting global options; right
	now only the default database type can be set

    o   dbLoad and db2env are regular functions now rather than
	generics/methods.  dbLoad's default 'env' is the parent frame now

    o   Added a "filehash" method for 'with'

    o   Added new generic dbUnlink which deletes a database from the disk
