After the update to 1.4.6 using an efficiency IV or V diamond pickaxe on grass or an efficiency IV diamond shovel on glass or glowstone does not affect the speed even though there is no report in the changelog that some bug related to this has been fixed or that the way enchanted tools work has changed in the update 1.4.6
In 1.4.5 and previous versions these tools would mine these blocks instantly on point.

Can you please post a link that supports what you say? How do you know it is a bug fix? In the changelog there is not such a bug fix reported.
MC-4645 is official.
There is no official statement that there where any changes that would affect the behavior of enchanted tools or about a bug fix neither in 1.4.6 nor on the 3 snapshots between 1.4.5 and 1.4.6
A link to a confirmed bug report of this bug (efficiency working on blocks that it shouldn't) would at least partially justify what you say. Instead I can only find MC-2796 where a player reports that efficiency enchantment affects the efficiency of mining the wrong blocks and the mod closes it telling him that there is nothing wrong with this behavior.
I made a valid objective argument to your subjective opinions (mod A says that it works as intended, mod B says that the opposite behavior works as intended) so I expect at least an answer that proves me wrong. Bottom line you are moderators not the development team so you could be wrong too (as already happened because Kumasasa in MC-2796 and Mustek and Tails in MC-5209 have conflicting opinions so only one side can be right).
Marios, isn't the resolution of Dinnerbone in MC-4645 not "official" enough ?
It's a bugfix, now they're only efficient on the blocks they were intended to break.
