	* Fixed SMTP configuration for login script so that unencrypted connections to gateway now
	  work.
2.00    * The "admin" user can upload public tracks. Use gbrowse_set_admin_passwd.pl to

	* Can now upload gzipped and bzipp2ed files for all file types.
	* SAM and BAM file uploading supported, provided Bio::DB::BAM library is installed
	  and there is a suitable FASTA file for the reference genome in one of the tracks.
1.9981  * The old-style upload code has been removed.
1.998   * WARNING: WIG FILE UPLOADING NOT WORKING.

	* Attempt to fix problem of FastCGI processes hanging around even after apache restarted.

        * Added abiity to tag tracks by their "track source" and "data source" and to turn them
          on and off using this information.
        * Added a track filtering ability via plugins.
	* Fixed FastCGI support so that changes to GBROWSE_CONF are recognized each time
	  the FastCGI server runs. This allows you to change GBROWSE_CONF on a per-directory
          basis using <Location> and SetEnv.
1.993   * Fixed bug in the cache expiration code that caused cache time to be set
	  abnormally low and prevented cached data from being cached.

1.988	* Fix handling of DBI databases so that various intermittent SQL errors ("server went away")

          to contain any features in current view to remain greyed out

1.90    * server farm rearchitecture introduced
	* big cleanup of defunct files; migrating to Module::Build

1.67    * Templates now the norm, use gbrowse_not to get the "no templates" version.

	with chado adaptor.

1.66    * The popup zoom menu will never show a region larger than the overview.
	* Fixed collapsible sections so that they store their state in transient named cookies
	  rather than in a single bit vector.

		"region segment" configuration option to turn this feature on.
	* Added ability to open and close sections with a JavaScript toggle.
	* Added ability to group tracks logically.
	* Added the "initial landmark" configuration option to bring up a 
		default region the first time user visits the web page.

		the links list underneath the instructions.
        * Added compatibility with mod_perl version 2 (via ModPerl::Registry)
	* Added the ability to highlight multiple features using URL arguments.
	* Added the ability to highlight multiple sequence regions using URL arguments.
	* Added the ability to turn off the autosearch feature which restores the previous
	        region when the user revisits the browser.

	        region panels, and loading Berkeleydb databases to tutorial.
        * Added a "hide" option to use when semantic zooming should turn a track
                off altogether.
	* Added README-lucegene.pod, describing the Lucegene GFF adaptor
	* The link option in the config file can now be used to override the built-in linking
		rules from DAS sources.
	* Moved plugins menu to a more prominent position.
	* Uploaded features can now be placed in details panel, overview panel, or both panels.
	* init_code subroutines and anonymous callbacks are now placed in the same package so that
		one can refer to the other.
	* The feature name search now no longer does a wildcard PREFIX search (*foo*), which was killing
		performance. It still does a wildcard SUFFIX search (foo*).
	* You can now use the parameters "enable" and "disable" to
		selectively open or close a set of tracks without blowing
		away the settings for all the other tracks the way "label" does.
        * gbrowse_img now takes a "highlight" parameter that will highlight the indicated
                named feature(s) in yellow.
	* gbrowse_details will now evaluate URL options expressed as anonymous subroutines (contributed
		by Cyril Pommier).
	* gbrowse_details now accepts a general formatting rule syntax
		that allows the formatting of each tag value to be precisely
		controlled.
        * Changed mainform submission method from POST to GET when MSIE detected,
                in order to defeat evil "cache has expired" message. This hack is
		under the control of the "msie hack" option, and is false by default.

	* Added request timeout option for very long requests.
	* Added additional padding to prevent scales of xyplot glyph from being
	cut off.

	features.  You will need to CVS update bioperl-live to get this feature.

	* Fixed the problem of three-frame translation glyph showing wrong
	translation.  HOWEVER, for the [x]flip feature to work properly,

	* Fixed the problem of segments shrinking by 1 bp when the starting
	segment length was an odd number.
	* Fixed problem of gbrowse_img consuming all available memory
	when displaying 3d party features in absolute coordinates.

	Katayama.

        URLs to corresponding cmap features

1.61    Wed Mar 17 21:59:16 EST 2004
        * Moved the BioSQL adaptor to 'experimental'.  It is not guaranteed
        to work.
        * Really fixed the landmark problem (the 1.60 release was premature)
	* Quashed warnings from the GeneFinder plugin
	* Suppress warnings generated by coderefs in the link and window_target
	options.  See make_map() to turn this back on - it might not be the 
	greatest idea to turn off warnings

1.60	Tue Mar 16 16:36:45 EST 2004
	* Fixed problem of some landmarks not being recognized using 
	the Class:Name syntax.

        * Fixed bug with link URL when the same feature type occurred in more
        than one track
        * Added SVG "Publication quality image" option; as a result, GD 2.07
        is the minimum version of GD required.
        * Added the ability to modify html display via callbacks utilizing
        segment and page setting objects.
        * Fixed alignment problems in gbrowse_details

	to 
	http://localhost/cgi-bin/gbrowse/yeast

	authentication/authorization techniques.
	* Default time for cookie expiration reduced to 7 days.  This will avoid
	issues arising from previous change.
	* Added mechanisms to restrict individual tracks by username and
        password
	or by host, domain, or IP address.
        * Fixed ppm install utility script
        * Updated documentation to reflect the new GET syntax
        * Fixed sequence alignments in gbrowse_details when there are minus
        strand sequences.

1.55
        * Removed hard coded paths in install scripts
	* Auto-open tracks that contain matches to the search term.  This avoids
	nasty behavior in which someone searches for "collagen" and never sees
	what it was that matched.
	* Support for highlighting the matched feature in yellow.  Highlighted
	feature is persistent across sessions (may annoy people - consider
	a selectable option)
	* Support for a "highlight" plugin class which will highlight features
	based on matching attributes or other queries.

1.54	Thu Aug 28 12:08:15 EDT 2003

1.47 	Tue Oct  8 14:44:44 EDT 2002
	* Bug fix release.
	* Fixed source sorting so that lowest alphabetically-sorted
	  configuration file is accepted by default.  Otherwise,
	  the default is BioSQL, which is not installed on most
	  machines and causes an internal server error.
	* Fixed the plugins so that they are not turned on by default.
	* Changed the default empty track style from "suppress" to "key."
	* Better error reporting.

	* If you pick up the latest bioperl-live (or apply extras/bioperl-1.0.patch)
	there are fixes in Bio::Graphics that prevent genes from disappearing
	when zoomed all the way into an intron.
1.38	Mon Apr  8 21:16:12 EDT 2002
	* Previous version would crash on vanilla Bioperl 1.0 installations.
