Difference between MTA and Nightly Builds?

[Paradise]

ok so im pretty new to MTA, i used to code and do stuff on SA-MP but i decided to come to MTA because it is awesome. The synch is so good and barely any lag. Anyways i was looking at the resources page and my question is theres some resources that only work with nightly builds, i know its a nooby question but what is nightly builds? and what are the difference between mta and nightly builds?

Since MTA went open source all the beta builds (nightlies) are free for anyone to download and test, they're called nightlies because they're built every at night and each one provides some improvements over the previous ones. Fixes are sometimes experimental so these builds can be crashy every once in a while but they're usually fixed in the next revisions.

Scripters tend to like nightlies more because they offer the latest scripting functions, fixes, features etc things that weren't there or maybe are deprecated in DP2.3.
