2  =======================================  =======================================
3    
4  Version: 0.0.4  [TODO -- write something here for first release]
 --------------  
 Date:    Jan 31, 2002  
 Author: Rich Kilmer <rich@infoether.com>  
   
 * Major changes  
 * Changed the Log4R logger to become a plugin  
   see: ./plugins/logger  
 * Removed the log4r code from setup.rb.  That file now sets  
   up an in-memory logger until a persitent logger is installed.  
   All log messages are queued in the memory log (limit 20).  
 * Added #prune method to Slot (to delete slots)  
 * Changed the term used for subscribers first param:  
   was: slot.subscribe {|message, slot| ...}  
   now: slot.subscribe {|event, slot| ...}  
   It really always was an event (Symbol)  
 * Added a manager to slots  
 * Added ./config/default.xml (default properties)  
 * Added plugin dependency management  
 * Added plugin transition management  
 * Changed plugin.rb extensively based on transitions  
 * Added freeride.rb which contains module and global constants  
   and requires all other freeride core files  
 * Changed run.bat to require freeride.rb instead of core.rb  
 * Added autostart attribute to plugin.xml to be able to disable  
   plugins from loading upon startup  
 * Added propagate_notifications attribute to Slot so a slot can  
   block sending notifications to parent  
 * Made a properties a Manager of a properties slot  
 * Added lifecycle methods to the plugin modules:  
   load    perform load operations (require files, etc)  
   start   start plugin  
   stop    stop plugin  
   unload  perform any (possible) unload operations  
   Note: Plugins MUST issue transition operations in these methods  
         for the plugin to continue to load (see SimpleTest Plugin)  
 * Added the ability for slots to have attributes  
   set: slot.attr_<name> = value  
   get: value = slot.attr_<name>  
   
   
 Version: 0.0.3

 * Major changes  
 * Single databus (plugins are relative paths)  
 * Refactored DataBus.  
 * Element has been renamed Slot  
 * Slots can have one of four types (per Curt Hibbs)  
     data    A Data slot holds a basic data object  
     queue A Queue slot holds a FIFO list  
     stack   A Stack slot holds a LIFO list  
     proc    A Proc slot holds a proc/block and can be called  
 * Subscriptions to slots now must accept two parameters  
     message  The message Symbol  
     slot         The slot object  
     dbus["/foo/bar"].subscribe {|message, slot| ... }  
 * Properties is rewritten...now sit on top of databus  
 * Logger is now mounted in the databus  
 * Refactored Core, Plugin and test plugins accordingly  
 * Added FreeRIDE::DataBus::Adapter class to enable  
   automatic update/sync of mutiple slots  
 * Added RubyUnit to the redist directory  
 * Added test dir w/a couple of (non-unit) tests  
   
 Version: 0.0.2  
 --------------  
 Date:    Jan 21, 2002  
 Author: Rich Kilmer <rich@infoether.com>  
   
 * Added ./Changelog.txt (this file)  
 * Moved REXML and added LOG4R to the ./redist directory.  
 * Got rid of startup.rb (moved functionality into run.bat)  
 * Changed the run.bat to start the core directly.  
 * When ruby starts it now adds the following paths:  
     .        The current directory  
     so      A directory to hold shared libraries/DLLs for plugins (future)  
     redist Redistributed libraries from 3rd parties  
 * Moved setup.rb into the ./config directory  
 * Moved the documentation under the ./doc and the ./doc/rdoc directory  
 * Refactored the core.rb file into 4 files.  This should make it easier to  
   change/refactor the core components.  
     core.rb - The FreeRIDE::Core class  
     databus.rb - The FreeRIDE::DataBus class  
     properties.rb - The FreeRIDE::Properties class  
     plugin.rb - The FreeRIDE::Plugin class  
 * Added support for Properties on the plugin object (as specified in the  
   plugin.xml file)  I plugin can now access its properties with:  
     @plugin.properties["PropGroup", "Prop"] = "value"  
     @plugin.properties["PropGroup", "Prop"] #=> value  
   Remember after a properties change to do:  
     @plugin.properties.write  
 * Refactored the DataBus.  Now, there is a Root element ("/") that can  
   be subscribed to.  The Navigation Module is no longer necessary and  
   its functionality is merged into the Element class.  
 * DataBus "publications" are now propagated to the parent Element so if you  
   publish to /foo/bar all subscribers of /foo/bar get notified as well as  
   subscribers of /foo and /.  
 * Added a logger to the core using Log4R. Its accessible from each plugin as:  
     @plugin.log.info "Information message".  
   The log file is configured in the core properties.xml file (./config/properties.xml)  
   Default is ./config/freeride.log  
   
 Version:  0.0.1
