Zenphoto.org is now running 1.4.2 Dec 10, 2011
We are pleased to announce that we have upgraded the Zenphoto site to the Beta of the 1.4.2 release. We believe the release is now stable (or we would not run our site on it.) I would expect shortly that we will generate our first release candidate for Zenphoto 1.4.2.
Please give 1.4.2 a try.
