After releasing 10.7.5 build 11G36 to developers just over 10 days ago, the next edition, 11G45 has just been seeded to developers. The combo update weighs in at 1.93GB while the Delta update is 1.16GB.
Apple above all wants developers to focus on graphics performance, and as of writing this latest build has no known bugs.
It will be interesting to see how long Apple continues to update Lion for, and this could very well be the last update if the rate of Mountain Lion adoption stays consistent.
