What are Houdini builds?
SideFX provides new builds of Houdini almost every day. These daily builds contain bug fixes and small improvements to the software. The detailed list of fixes is available in the journal under the Support menu. By installing a daily build, users are often able to benefit right away from our agile development process.
SideFX periodically designates a daily build of Houdini as a "production build". Production builds are released almost monthly and have gone through the full quality assurance process, so they are at least as stable as the original. It is thus advisable to upgrade from time to time, particularly from one production build to another to take full advantage of new improvements.
