The terrain module has been updated with code that stores the terrain as compressed data for faster retrieval and more efficient space use in the database. The max terrain elevation can now be 655.34 meters – which is compatible with the SecondLife limitation.
The http handler for scripts have been updated with a limit to the length of a http request from a script. The default is set to 16384 byte, but it can be changed at the simulator level if needed. The limit is set both as a prevention for exploits via the scripting mechanism, but also to limit the ability for scripts to do web page scraping.
