The continuous integration server (provided by CloudBees via their FOSS program) provides development builds for MyWarp, build directly from source. While these builds are always up-to-date, they may contain unknown bugs and functions are subject to change. If you are unsure what this means, do NOT use them and stick with the stable builds released on bukkitDev.
Disclaimer: Development builds of this project can be acquired at the provided continuous integration server. These builds have not been approved by the BukkitDev staff. Use them at your own risk.
