Hi everyone,

> ImageJ and Fiji update sites this Friday, December 19.

The update is complete: the release version of ImgLib2 is now distributed
with ImageJ. All libraries and plugins on the ImageJ and Fiji update sites
have been updated accordingly, and should continue working as before. As
always, please report any issues you encounter.

This update also includes the BigDataViewer libraries and plugin suite on
the core Fiji update site. If you have the BigDataViewer update site
enabled, you should disable it in favor of the BigDataViewer that ships
with Fiji.

Thanks to everyone who helped make this update possible!


P.S. If you have any other update sites enabled and they are not working
correctly (especially if you see errors containing "ClassNotFoundException"
or "NoSuchMethodError" with "net.imglib2"), chances are that the author of
those plugins needs to update them to work with the release version of
ImgLib2. Please report such issues via Help > Report a Bug.
