As summarized by DaringFireball, Apple has loosened their restrictions of section 3.3.1 of its iOS Developer Agreement:
In particular, we are relaxing all restrictions on the development tools used to create iOS apps, as long as the resulting apps do not download any code. This should give developers the flexibility they want, while preserving the security we need.
The removal of these language restrictions is essentially good news for Unity developers (read their statement), and those who wish to develop iOS Apps using a Flash cross-platform compiler and also those using Corona Game Edition, which is entirely Lua-based. And speaking of which, Corona offers developers to purchase Corona SDK and Game Edition at just $99 until only September 15th, after which you’ll have to pay for each product seperately and the price goes up to $249. Just in case you were eye-ing it.
