1.0.4 Improve wave simulation & fix bugs

Major internal refactoring to reduce technical debt and increase stability
Many small improvements to wave simulation
Improvements to integration between wave simulation and the rest of Issie

UPDATED just before 22:00 8 Nov to add in additional stability improvements on loading files which create draw2d errors.
UPDATED 11:15 8 Nov to remove confusing check on Splitwire having a label - Splitwire cannot be highlighted...

1.0.3 bug fix, features

Bus labels were not working in simulation, this is now fixed.

The memory editor did not properly do error checking, radix change, and did not display numbers with the correct number of leading zeros.

All now fixed with a new design that displays and edits up to 16 contiguous locations starting at any initial location

In addition the handling of large memories has been improved. Sparse implementation means that address width of up to 64 bits can be allowed and correctly simulated.

Finally the delete key (deleting diagram figures) as been documented on the edit menu. Note that this is Now the BS key on macos - Func-BS no longer needed.

1.0.2 Production version: improved

This has a collection of minor bug fixes from v1.0.1, e.g. working N bit adder. For windows: unzip the issie-1.0.2-win.zip file to a directory somewhere in your user file space (it will be 200MB unzipped). Run Issue by double-clicking top-level file issie.exe in the unzipped directory. Note that on department cluster machines the directory you use must be on your h: drive, this is not an issue working from home.

For macos - download the dmg file. Double click this and either double click the application you can see, or install it by moving it to the applications folder in the window (as normal for macos dmg files). There will be some security over-rides needed since the application is not signed, which depend on your macos version. Ask gtas with macos for help with this, we will have steps documented soon.

1.0.1 First production

This is the first release of Issie for mass testing by students.

Improve UI performance

Large improvement in view function speed got from using lazyView on catalogue Tab. More performance improvements to come...

Various minor UI look and feel changes

Alpha release for testing

All features complete:

still known TODO:
some (not breaking) performance issues
code is messy - parts need refactoring
UI with viewer is not quite in final form, and a bit rough
error dialog on opening projects with malformed files cannot be cleared (but this should not happen normally)
