Did some tweaks to last week's two new features, especially HIDDENCAT, which got some significant new functionality.
Fixed a few bugs (11980, 12122 and 12970) which affect non-Wikimedia users, in preparation for a release.
Did some feasibility work into the idea of creating our own open-source audio CAPTCHA. Unfortunately cross-correlation appears to be a powerful and efficient technique for detecting known tagged recordings mixed with noise.
Started work on bug 13071, Cortado completely broken on Linux with Java 1.6. Required a lot of detailed study of this unfamiliar code, and may lead to a few other cortado bug fixes.
