-* Pulse detection algorithm (used to detect beeps and flashes) improved. Needs extra metadata fields in JSON metadata files, so will not work with existing metadata files generated by earlier versions of the test sequence generator.
-* test sequence generator modified to add extra metadata fields (to support pulse detection algorithm improvements) that describe the duration of the beeps and flashes in the test sequence.

+## 0.3 : (02 Sep 2015) Flash/beep detection improvements, customisable test sequences and various bugfixes
