After working some months with version 2.2.1 I saw some bugs which
should be fixed. Especially the CAL converter did not work as expected
in every case. Now I tried to use a regular expression comparison to
enforce a correct detection of real CAL blocks in IL source code.

I have some more small improvements in mind and a new release will
come during next month. Just ask me if you need a preliminarily release
with the current fixes ask me.

Today we see a minor update of PLCEdit - Version 2.2.1. It comes with some
bug fixes and also some nice to have features. Implementations of bigger key
features will not placed this year, maybe. So, also the support of OpenPCS is
not yet included as separate entry in the open and save dialogs.

Ok, what’s changed in v2.2.1?
First of all the session manager can now redirected to a user defined path.
Use the Default button at the preferences dialog if any problem occurs with
the session manager or the selected path.
Next PLCEdit contains now an update function to inform about updates of
the application.
I tried again to fix the tab/file list bug which occurs by saving a file if some
more files are opened.

After a couple of month I proudly present the new major version of
PLCEdit. Version 2.2.0 comes with a lot of new features and got some
good enhancements under the surface.

The new key features are:
- support for Mitsubishi MELSFOT IEC files
- the function block call model converter

Next the support for infoteam’s OpenPCS has started. First files
of OpenPCS will be accepted as plain text POUs. Later seperated
entries in the file open and save dialogs will be added. The sources
are very clean, so there is only something to do regarding the file
extension management in PLCEdit.

I know, I said we will see a new version until end of October. Now we’ve
mid of December. I’m sorry but I had a joyous occasion in private.
And next I’ve found some problems in using the beediff source for the file
differencing function. I think I have to rewrite a lot of routines to hold the
promise „never create any registry entries“ and to make the differencing
really work.

So, for the moment I’ve canceled the file differencing function and will only
have a look to the function block call conversion functionality and the new
Mitsubishi Melsoft support.
Hopefully I’m able to release version 2.2.0 during the next week or better
before the new year is there...
