Cadcorp Service Release Announcement - 24 March 2017

Cadcorp is pleased to announce a Service Release of all products using release 8.0.2148 on 9th March 2017.

Since the release, we have been made aware of a problem with coordinate transformations between WGS 84 and OSGB British National Grid.  Because of an error in the updated transformation parameters, data created using WGS 84 and viewed in OSGB British National Grid could be displayed incorrectly, by about 100 metres.

We have corrected this error and issued new installers on 22nd March 2017.  A hotfix is available as well.
