What’s New in FoCal 4.6

Welcome to FoCal 4.6

This is a bit of an internal tidy-up release.

We’ve fixed a good number of minor bugs which will improve stability, reliability and in some rare cases accuracy of the results.

Camera control functionality for all cameras has been improved, reducing the load on the computer/mobile device during wait times, and improving handling of failures in communications.

License Requirements

FoCal 4.6 is available to anyone within their Included Updates Period as of 26th May 2025 – if you’ve bought FoCal or renewed your support less than 12 months before this date, you’re good to go.
