	- Renamed sql_interpolate and dbi_interpolate to sql_interp
	  and dbi_interp respectively (thanks terrence).

0.29	2004-12-25

	### SQL::Interpolate features

	- Added support for ("IN", $scalarref) (thanks mark s)

	- Added support for ("INSERT INTO mytable", $scalarref)

	- Added support for ("INSERT INTO mytable", $arrayref)

	- Added support for ("WHERE {x = 3, y = 4}")

	- Added support for ("INSERT HIGH_PRIORITY DELAYED INTO mytable", $ref)
	  for mysql.

	- Added simplified syntax for table joins using
	  R(...) and LINK(...) macros via new method filter_sql().

	- Added OO-interface in addition to the functional one.

	- Added support for \%attr to be returned by dbi_interp()
	  and sent to DBI when new SQL::Intepolate::Attr object is given.
	  This object may be created by new attr() function.

	- Added support for extra $key_field to be returned by
	  dbi_interp() when instance of new SQL::Interpolate::Key object
	  is given.  This object may be created by new attr() function.
	  This is for using in DBI::selectall_hashref and similar methods.

	- Added exports:
           attr, dbi_interp, select_key, limit, make_sql_interp,
           make_dbi_interp, filter_sql, sql_flatten, limit

	- Added debugging options in use statement: TRACE_SQL, TRACE_FILTER.

	- Changed: less extra whitespace around SQL generated by sql_interp().

	- Changed: In limit(), for mysql, don't use bind values since they
	  don't always work right.

	- Changed: In limit(), for mysql, $start and/or $count may be undef.

	### SQL::Interpolate internal changes

	- Dereferencing extra reference that source filtering produces from
	  sql[$x] when $x is an arrayref or hashref is now performed more
	  immediately in SQL::Interpolate::SQL::new() rather than sql_interp().

	- new SQL::Interpolate::Limit extends SQL::Interpolate::Macro.

	- Moved SQL::Interpolate::SQL into SQL::Interpolate

	- Fixed some documentation (thanks mark s)

	- Added more tests, more complete docs

	### DBIx::Interpolate features

	- Added new() method in addition to connect() to attach existing
	  database handle (thanks mark s)

	- Added dbh() and interp() methods to expose underlying DBI and
	  SQL::Interpolate objects.

0.30	2005-01-10

	## General

	- Refactored SQL::Interpolate module into multiple modules.
	  Everything except sql_interp-related functionality
	  moved out of SQL::Interpolate and into DBIx::Interpolate,
	  SQL::Interpolate::Filter, and SQL::Interpolate::Macro (new module).
	  (recommended by mark s)

	- Reorganized macro processing.  SQL::Interpolate contains
	  only hooks for macro processing, and SQL::Interpolate::Macro
	  implements various macros.

	## SQL::Interpolate

	- added sql_var type

	- added sql_literal type (thanks mark s)

	- ("WHERE x in", []) now generates "WHERE 1" not "WHERE NULL"

	- croak not die

	- macros, sql_var, and sql_literal can now exist in
	  elements of aggregates (hashref and arrayref)

	## DBIx::Interpolate

	- DBIx::Interpolate is now derived from SQL::Interpolate.

	- Support for statement handle sets (stx/prepare).

	- Renamed select_key() to key_field().

	## SQL::Interpolate::Macro

	- SQL::Interpolate::SQL is now a macro for uniformity.

	- new macros: relations, sql_and, sql_fragment, sql_if,
	  sql_link, sql_or, sql_paren, sql_rel

	- removed limit() macro since MySQL supports Postgres syntax.
	(thanks mark s)

	## Other

	- reorganized POD (thanks mark s)

	- reorganized test cases

0.31	2005-09-27

	## SQL::Interpolate

	- Improved error reporting by sql_interp
	  (recommended by mark stosberg)

	- Added support for ("WHERE", {x => \@v, ...})
	  ==> "WHERE (x IN (?,...) AND ...)".
	  (recommended by multiple people)

	- Generate 'WHERE id = 5 and 1=1' and 'WHERE id = 5 or 1=0'
	  rather than 'WHERE id = 5 and 1' and 'WHERE id = 5 or 0'
	  for Oracle compatibility.
	  (reported by wojciech pietron)

	- Fixed some improper handling of "use"
	  parameters, e.g. $x in "use SQL::Interpolate FILTER=>$x"

	- Fixed various Exporter problems from custom import
	  (reported by mark stosberg)

	- sql_interp.t and dbi.t - Fixed test case errors due to
	  different hash order on MacOS.
	  (reported by sean davis)

	- Documentation improvements.

	## SQL::Interpolate::Macro

	- Fixed: '^' and '$' are no longer
	  automatically placed around regexes in 'relations' parameter.
	  (reported by wojciech pietron)

	## DBIx::Interpolate

	- Added support for transparent
	  caching of statement handles (no need to prepare()).

	- Fixed error in STX::fetchrow_hashref returning an
	  arrayref rather than a hashref.
	  (reported by mark tiefenbruck)

	- Added Carp
