Hi all, We're proud to release yt version 2.5.2. This is a scheduled point release that includes all bug fixes identified and fixed since the release of 2.5.1 on April 1. Changes and bug fixes include: * Upgrades to most of the dependencies in the install script * Speed improvements to ellipsoidal particle detection * Updates to FLASH fields * CASTRO frontend bug fixes * Fisheye camera bug fixes * ProjectionPlot now accepts a data_source keyword argument * Answer testing now includes plot window answer testing * Athena data serialization If you are using the stable branch of yt from an installation script, you can upgrade using "yt update" or "yt update --all" to upgrade your full dependency stack. If you are using the development branch, you may already have these fixes. A tarball of this release has been uploaded to the Python Package Index (PyPI), although due to user error (me) it includes the Cython sources instead of the C sources for the generated code. Oops. Thanks very much, Matt, on behalf of the yt development team
