I can see maps being useful for people who can't play online well, since you could fill a map, put in inventory, then save and send your map to people and share your world easily.
However
There are many fixed 'glitches' that will induce the fury in many people. Since said glitches are infact considered game mechanics these days.
* Made booster tracks speedier
Very likely to still not be able to overcome momentum limit
* Seeds are now found in tall grass, using a hoe on the ground no longer works
which spawn in only specific biomes. Quite a few people are saying "oh tall grass is just cosmetic, wont affect me" wrong, making bread is already a shit to do and hardly worth the effort and time put into it, and now you cant just do it either.
* Fixed a system clock change messing up the game speed
bit annoying. if your waiting for say, grass to grow, open the inventory and go on IRC for a while.
* Fixed rain sounds not playing with fast graphics enabled
I wouldn't have called that a glitch, if you are running with lower settings you'd rather less processing was being used... if the computer is slowing down, sounds fuck up terribly.
* Fixed submerged boats rising very very fast
Boat elevators - now pointlessly slow.
* Fixed falling while riding not dealing damage to the rider
Boat elevator returns can't just be a straight drop anymore.
* Fixed dispensers shooting through walls
didn't know about this personally but sounded pretty damn cool for a trap level.
* Fixed entities reaching water through wall corners
water ladders no longer possible.
* Fixed ice so it regenerates regardless of whether it?s snowing or not
just wait for your world to hit an ice age!
* Fixed minecarts next to each other causing extreme velocities (sorry!)
Trololololol - so many useless rail systems out there now! hahaha
* Fixed animals only spawning near light during the night
Thought this was a core mechanic? So long, friendly mob spawning machines!
* Fixed records not playing for other players in multiplayer
Noisy neighbors!
Stuff with good potential I see on the bug fixes
* Fixed network packets being sent unbuffered, causing huge amounts of packets being sent
This might fix the horrible lag that keeps happening online perhaps (when combined with the clientside limiting)
* Fixed loads of exploding tnt generating way too many particles, possibly crashing the client
Nice, might see TNT blasts that aren't slideshows now.
* Fixed a game crash when riding a vehicle or animal into the nether
Has potential but we'll see on this one.
* Fixed fences and stairs sometimes becoming invisible
Useful, to be honest. I've had this glitch a few times.
* Fixed rail tiles sometimes not properly connecting to a new neighbor
useful, this was damned annoying building big rail links.
I'm waiting for piston mod personally. Also I'd love to see minecarts coupleable into trains. As now the only realistic way of travel imo is powered minecarts (which is actually what my rail ran on anyway) but they are a bit of a pain in the arse to set up, since you have to flip the train around manually at each station. coupling so you could just send the powered cart any direction and the minecart goes with it infront or behind would be awesome.
