+
+Core
+----
+* Fix bug #220, Interchange server crashing in Server.pm. Caused by
+  inappropriate "next" upon select timeout after MaxServer > Num_servers
+  condition.
+
+* Change default of [catch] to NOT interpolate. Impossible to conditionally
+  execute code if that is the case.
+
+* Fix [catch] to work with only the proper body, not with both THEN and ELSE.
+
+* Add maxsize parameter to file write in tag_value_extended, fulfilling
+  enhancement request #99 in Bugzilla.
+
+* Add a filter for decode_entities, and make encode_entities an alias to
+  entities.
+
+* Add ability to restrict tag execution in a region. If a restricted tag is
+  encountered, it is simply output. Based on an idea from Jon Jensen.
+
+  [restrict policy=deny*|accept enable="tag1 tag2" disable="tag1 tag2"]
+      restricted area
+  [/restrict]
+
+  options:
+  policy   "allow" or "deny". Default is deny.
+  enable   space or comma-separated list of tag names, including
+           UserTag names.
+  disable  space or comma-separated list of tag names, including
+           UserTag names.
+
+  For instance, this:
+
+  [restrict enable=page]
+      [area something]
+      [page aboutus]A link[/page]
+  [/restrict]
+
+  will output something like:
+
+      [area something]
+      <a href="http://sam.heins.net/cgi-bin/mfound/aboutus.html">A link</a>
+
+  Defaults are important:
+
+  interpolate=0
+  reparse=0
+
+  It would defeat the purpose to set interpolate or reparse, but it can be
+  done.
+
+* Allow parameters for comment tag -- not parsed, but at least tolerated.
+
+* Fix some Interpolate.pm bugs in option display to allow overriding for
+  simple options too, and to select the widget type for matrix options.
+
+* Add get=1 to setlocale tag. That is sort of counter-intuitive, so I added
+  a [getlocale] alias for [setlocale get=1].
+
+* Fix makecat instructions on how to set ShareURL if using ~yourname/
+  style paths, and allow ShareURL to be empty if passed from command line.
+
+Admin UI
+--------
+* Added German UI images and other text translations.
+
+* Automatically symlink to default en_US UI images for missing images in
+  other locales.
+
+* Fix problem with IMAGE_DIR variable being inadvertantly changed for store-
+  front by UI. (Thanks to John Beima for finding this.)
+
+* Fix area and cat reordering problem in layout.html of admin with a patch
+  from Mark Johnson. Fixes bug #180.
+
+* Finished help pages for the Wizard.
+
+* Make UI_SECURE behave so that global policy can be enforced --
+  i.e. if @@UI_SECURE@@ = 1 then the setting of __UI_SECURE__ does not matter.
+  @@UI_SECURE@@ isn't set in the foundation demo, so this doesn't affect
+  current defaults.
+
+* Move @@UI_STD_HEAD@@ before item bounce checks, so that when the bounce
+  occurs it will go to the right URL. Because we now use [table-editor],
+  the positioning is no longer necessary. Should fix Bugzilla bug #217,
+  though that was marked invalid because we don't support different
+  SSL/non-SSL domains.
+
+* Fixed missing mv_session_id variables in admin UI form posts, causing
+  problems when cookies were not used.
+
+* Add database-table based backup capability. Depends on a table "backup"
+  being available. Looked at CVS, but the repository creation/management
+  issues are too daunting at this point. Since it is likely that an entire
+  catalog would want to be in CVS, this partial solution seems wiser.
+
+* More improvements to page editor:
+
+  - Policy for editing individual components/page/template can be set in
+    template as well as globally. Soon we will have per-page and per-user
+    control.
+
+  - A PREAMBLE and POSTAMBLE area is defined, so that code can be run before/
+    after template regions without being restricted to what you can do with
+    the page settings.
+
+  - preamble and postamble are editable on a per-template basis.
+
+  - Preview works on latest version of Mozilla, Netscape 4, and MSIE 5.
+
+* Usertag changes:
+
+  - Update read_ui_page to support latest page edit.
+
+  - Add diff tag in support of new backup capability.
+
+* New, improved admin UI graphics make you healthy, wealthy, and wise.
+
+* Minor [table-editor] fix affecting special Wizard profiles.
+
+Foundation
+----------
+* Add supplant=1 to master route. Left in "main" so that it would be
+  compatible with old checkout forms, shouldn't cause any harm.
+
+* Turn off transactions by default in catalog.cfg -- not needed or wanted for
+  MySQL and DBM, two most common dbs. Since we have had virtually zero
+  complaint about transaction atomicity in general, it makes sense to disable
+  this. If someone wants transactions, they merely need to enable the
+  TRANSACTION_TABLES variable.
+
+* Add currency_locale field to transactions, resolving Bugzilla enhancement
+  request #128. This is valuable because if there is an exchange rate
+  situation, it needs to be known at time of purchase.
+
+* Include options in the emailed receipt and report.
+
+* Fix product description display in receipt.html.
+
+* Add example for configurable spec sheets for products. Can be extended to
+  track lists for albums, etc.
+
+* Fix template settings for some lesser-used pages.
+
+* Fixed a small typo in the 'cross' component. width_percent was set to 100,
+  instead of 100%, causing an occasional cross item to look very skinny.
+
+Other
+-----
+* RPM specfile reworked to build 3 RPMs: core, foundation skeleton, foundation
+  live demo. Foundation demo made friendly for relocation by RPM build.
+
+* Various cleanups: removal of unneeded variables, files, etc.
