while I agree changelogs are needed I think there are two very good reasons why they are not being posted at present.
The first is some hotfixes ect dont actually effect the game are are more backend stuff and
secondly the main reason is feedback.
If they hotfix/patch something that effects the game and/or deals with a complaint alot of people have by not posting changelogs the feedback they get is unbiased and gives a much more accurate gauge to see if what they did had an effect.
it eliminates the placebo effect , by that i mean if for example they have said oh we patched the lag alot of people would post yeah its alot better just because they think it should be..
whereas a better indication would be to say nothing and wait for the hmmm is it me or is the lag suddenly better/worse comments to start piling in.
*disclaimer this is my own personal opinion based on when i used to be in the game industry and also didnt post changelogs (ok sometimes i was just plain lazy)
