Minecraft: How Long Does It Take For Optifine HD To Update?

I know every time Minecraft updates optifine have to work on updating their mod so its compatible with the new update, but i looked at their page and comments asking for it to update for 1.9 is like febuary 29th and the update came out in march 22nd? I find it extreamly hard to play without shaders on my server, its so vaniila and boring, i don't want to wait months for it to update. Me and my friend are working on a machinima and we need shaders for it to look good. If anyone knows how long it takes for a mod to update thanks in regards.

Nobody knows as it purely depends on what needs to be change for Optifine to work properly with the current version of Minecraft. The only people who can estimate how long it will take is the developers of Optifine and they don't disclose that information.
