v0.3.4 Changelog 15.10.2018

Changes

• Components and Bonds are now order aware

Fixes

• Bug fixed in the handling of invalid parameters

v0.3.3 Changelog 25.09.2018

New

• Improved support for symbolic parameters

v0.3 Changelog 19.09.2018

New

• Users can now save a load to file.
• Source Sensor component has been added
• SS component can be exposed using expose to create IO ports.
• Model hierarchy can now be traversed in a posix-like manner using component.uri as unambiguous references

Changes

• The reaction builder no longer uses the 'Y' component
• Certain connections are now order aware (1 junction for example)
• Rebuilt how ports are referenced
• Moved all 'verb' actions out of class definition; including (new, add, remove, connect, disconnect)
• Find has been removed; users can now use uri

Fixes

• 1 junction now corresponds to the existing literature
• Drawing algorithm now has half-arrow heads
• Updated to sympy v1.2
