Here you can see what is new in various versions of CPN Tools and Access/CPN and which versions of Access/CPN works with which versions of CPN Tools. The list is not necessarily comprehensive, but lists the major changes.
The list may also reflect features in versions of CPN Tools that have not yet been publicly released, and as such reflects changes that are currently in the source repository but have not yet been deemed important enough to make a general release.
Fixed wrong bounding box for printing with collapsed current marking
Fixed partial state-space problems with automatic progression
Don't start text editor on constraints
Fixed cloning Declare constraints
Fixed deleting Declare constraints
Fixed (disabled) interplay between Declare constraints/reset arcs/inhibitor arcs and substitution
Graphical improvements cloning reset/inhibitor arcs
Fixed bendpoints for Declare constraints
Fixed drawing problems when deleting Declare constraints
Declare constraints are now checked incrementally
Load/save Declare works
Fixed last Declare constraints
Option for setting memory for simulator extensions
NOTE: Models using Declare saved using previous versions are not compatible with this version! Such models will not be compatible with any future version.
Add labels from external sources
Model statistics (tool tip on model name in index)
Improved aux graphics
Allow extensions to add instruments
Re-expose ogpath and
Fixed a bug causing the cursor to blink in weird ways
The linux simulator is back
this page before using this or asking for support!!
More control over simulation options for fast forward simulation (total number of steps, end time)
Time-equivalence reduction for state space analysis.
Ranges supported for time stamps (using extensions):
No longer fails if extensions are not started.
ONLY USE THIS VERSON TO TEST SIMULATOR EXTENSIONS It does not yet gracefully degrade if you don't! You will not be able to create nets without extensions, and extensions are not yet optimized, making this version seem significantly slower.
Graphical tweaks (for port places, arcs, binders + sheets, background)
Improved support for working with low-level nets; demo:
Preliminary support for DRAWING inhibitor + reset arcs
Preliminary support for DRAWING ordered + bounded places
3.4, 3.2, 3.0
Improved handling of monitors
Better handling of starting simulator; should work in packaged jars and Eclipse workspaces on all platforms.
Update for CPN Tools 3.4.0
Update to be compatible with CPN Tools 3.2.2.
Facilitate synchronization on
Improved handling of (integer) time during cosimulation.
Better support for loading while not connected to the internet (thanks to Stephan Schweig)
Better support for running from source (thanks to Stephan Schweig)
Improved export to .cpn files (including automatic layout if desired)
