Japanese Cherry Blossom was the second theme I ported to Habari, a task I undertook for a friend's band, Bitter Sweethearts. Even for a theme that might have a couple of users, making sure that the theme is up to date with the latest Habari features was taking more time than I wanted to spend, given what should be my priorities (my beloved and, yes, finishing my PhD). So, following the recent release of Japanese Cherry Blossom 0.2, the theme has been relicensed under the ASL 2.0, with permission from the author, April D. Spreeman, and I've committed it to the Habari extras repository, where it can be maintained by the Habari community. You can now download the theme from the Habari project website distribution directory, or using subversion (recommended).
Feature requests and bug reports should now be posted on the Habari extras trac.
