	* ExtProc module is now built as a shared object
	* libperxsi.so no longer retains old version of ExtProc when upgrading
	* can now run 'perl -cw' to check syntax if you preload extproc_perl.so
	* create trusted code directory during installation if it doesn't exist
	* rewrote gen_module_libs so it works more reliably
	* installation will warn you when shared objects are not found
	* bootstrap failure errors are now more consistent and verbose
	* is_null and set_null methods manipulate NULL status of oracle
	  datatype objects

1.99_05 Sat Jan 17 16:59:49 EST 2004
	* support for DATE types
	* methods for manipulating DATE values in Perl
	* existing libperlxsi is no longer overwritten during installation
	* set NULL indicators for IN OUT & OUT types
	* fix inc_path_to_mflag crash on solaris

1.99_04 Sat Dec 27 18:48:07 EST 2003
	* implement NULL, LENGTH, and MAXLEN indicators for variable length
          data types like VARCHAR2
	* allow user-defined attributes in dbi_connect
	* move put_line into ExtProc and remove from ExtProc::Util
	* implement filehandle interface to put_line
	* make ExtProc object-oriented (needed for put_line filehandles)
	* correctly pass NULL parameters as undefined scalars for directly
	  executed subroutines
	* autogenerate external procedure DDL in Perl.create_wrapper
	* wrote the user's guide (currently only available online)

1.99_03 Sat Dec  6 22:51:11 EST 2003
	* disallow eval in taint mode
	* register .fini function (ELF) to call pl_shutdown at library unload
	  VERY EXPERIMENTAL, but it seems to work well on both linux & solaris
	* can register user-defined destructors using register_destructor
	* implement IN OUT and OUT parameters
	* changed Perl.create_wrapper syntax to better reflect Oracle's syntax
	* prefix C wrapper function names with EP_ to prevent name clashes
	* full documentation is now available from the user's guide

1.99_02 Tue Nov 18 11:00:11 EST 2003
	* can directly call Perl subroutines, bypassing the generic
	  func & proc wrappers
	* Perl.create_wrapper creates C wrappers for directly calling subs
	* beginnings of support for non-VARCHAR2 IN & RETURN values (just
	  integers for now)
	* perlxsi.mk and other relinking files are now installed in the
	  trusted code directory

1.99_01	Sat Nov  8 12:19:19 EST 2003
	* initial alpha release (pre-2.0)
	CHANGES BELOW ARE RELATIVE TO the 1.03 codebase:
	* globals incorporated into single global EP_CONTEXT struct to minimize
	  use of globals and lay the groundwork for future threading support
	* gen_module_libs rewritten in perl for portability & accuracy
	* all oracle functions/procedures now in "Perl" PL/SQL package
	* perl function is now Perl.func
	* perl_p procedure is now Perl.proc
	* former "special subroutines" are their own PL/SQL procedures in the
	  Perl package
	* func & proc now take up to 8 arguments by default
	* debugging and tainting support are always built in
	* new configuration file with various runtime options
	* tainting is now a runtime setting
	* bootstrap file path is a runtime setting
	* can specify additions to @INC as a runtime setting
	* can specify debug directory as a runtime setting
	* simple_query.c and simple_query functions decommissioned
	* oci.c now contains all significant OCI routines
	* ExtProc "convenience" routines removed
	* new fetch_code routine dedicated to fetching code from database
	* code in database now stored as VARCHAR2 instead of CLOB
	* support for per-session namespaces (packages)
	* renamed ExtProc::exception to ExtProc::ora_exception
	* ExtProc::is_function & ExtProc::is_procedure will tell you the
	  context of the current call
	* split module shared objects into their own library, libperlxsi,
	  so they can be maintained separately from extproc_perl.so
	* perlxsi.mk Makefile is installed to facilitate linking new modules
	* perl_config view contains configuration settings
