Teemo re-work patch notes: http://www.surrenderat20.net/2015/07/723-pbe-update.html#teemo
My opinion: they are both good and bad.
Camouflage rework was much needed, but it was short-sighted because it disincentivizes maximizing AS with many on-hit builds. (You don't want to build past 2.5 AS since it's capped. Teemo currently reaches this cap with 204.66% increase in attack speed at level 18.) Like Nidalee's brush passive, it can be quite situational. This change also pushes him into the top lane role more, where you rely much more on brushes, or in the jungle.
The shroom rework is also interesting because it makes it easier for Teemo to shroom outside of lane, basically giving it a trinket range. This won't be beneficial for Teemos that use shrooms aggressively by placing them in lane for combat. It does however, reward safer Teemos that like to use it as an alert system in lane.
The fact that shrooms can bounce off one another will likely be useless in combat, given the amount of time they take to stealth before being destroyed. You would also need to stockpile shrooms to take advantage of the bouncing effect, which is rare if you are a good Teemo player.
If Riot decreases the length of time that shrooms need to stealth, or that they explode immediately on landing, then we could be talking about something else: sort of like a nuke instead of giving the enemy champion a free 10 gold or something they can easily dodge.
Of course, there is a huge nerf: shroom times are effectively being halved. This is huge, and effects all roles and play styles of Teemo.
So there you have it: buffs to camouflage passive, and R shrooms get a (useless in combat) gimmick and a big nerf.

Teemo has a unique play style and is incredibly versatile. The only champion that is similar to his play style is Kayle. This guide who show you Teemo's complexity. Teemo is an easy champion to play, but difficult to master. Playing him at a high level requires you to have strong mechanics and good map awareness.
