I think it's time for a new release. I have updated the release notes to include the TIFF memory fix and OSGi bundle. Thanks to the new contributors!

(BTW: I have also invited all contributors to be owners/committers of this github organization)

I guess version 1.3.1 is OK, even though we are now an OSGi bundle?

Anything else that needs to be updated before the release? I will prepare a release candidate.
