Changelog

High-level changelog. For details, consult the SVN logs.

3.1.2 (2011):

• added some docs
• more configurable importTopicTree
• using importTopicTree now allows to use the topic hierarchy as topic names instead of string, thereby enabling python editors to support pubsub-based development via code completion and sendMessage keyword arguments.

3.1.1 (2010; beta):  

• cleanup docs
• couple minor tweaks (for instance added pub.getMsgProtocol())

3.1 (2009; beta):  

• Import/export of topic tree and its documentation using Python interpreter
• Better support for evolving topic tree during application development, with “freezing” certain parts of tree
• Helper functions to transition from arg1 to kwargs messaging protocol
• Improved error messages (in exceptions raised)
• pubsub can be installed inside other packages and will not interfere with system-wide pubsub
• pubsubconf module moved inside pubsub package so manual install easier
• Support !**kwargs in listeners
• Support for more than one pubusb notification handler
• Multiple publisher engines in one application (for instance, in separate threads, or for different “domains” in a large application)
• Upgraded docs
• Bug fixes, cleanup

3.0 (2008):

• Use keyword arguments in sendMessage
• Support any kind of listener, not just those with one unnamed argument
• Validate listeners at subscription time
• Support “inheritance” of keyword arguments by subtopics during message sending (prevents a common bug which was to send data using wrong argument names).
• Topic tree can be documented (including topic message arguments)
• Support user-defined notification handling of certain events occuring in pubsub such as “subscribe”, “sendMessage”.
• Support user-defined exception handling of exceptions raised by listeners
• Proto-Documentation on own website using Sphinx
• Separate regression testing folder for nose-based automated testing
• Configuration module for choosing which pubsub API to use in application, useful for backwards compatibility

2.0 (2007):

• more Pythonic API (new PublisherClass API, at module level so easier to call – no need to know about singleton)
• Support definition of topic tree via a python class, for increased rigor and documentability of topics
• Topics are objects

1.0 (2005):

• Given its own “home” as separate package from wxPython’s wx.lib.pubsub
• Factored out weakmethod
• Put on Cheese Shop

Pre 1.0:

• Created by Rob Shecter in wxPython’s wx.lib (early 2000?)
• Weakmethod added by Oliver Schoenborn (2004)
• Further development transfered to Schoenborn (2004)
