I'm in two minds about whether to add OCaml 4.02 to Fedora 21: - The only significant change that we care about is full AArch64 support. Currently Fedora 21 uses an AArch64 backend that I hastily backported from upstream before the upstream backend was completely finished (which, to be fair, does appear to work). - The upstream schedule is rather unfortunately misaligned with the Fedora 21 schedule. 4.02+beta1 was released last month. More betas/RCs are expected. But final release is going to be August (ie. after F21 development freeze). - There are quite a lot of bug fixes (something like 40+) which would be a pain to cherry pick individually to F21. However none are known to affect Fedora users. - There are several new optimization steps in the native compiler, which might be interesting (in good and bad senses of the word). Anyway if anyone has any preferences either way, then follow up ..
