I've been a cosmologist for a decade and nothing fundamental has changed in that time, except increased precision of our measurements. Nobel laureate John Mather's take: http://www.bbc.com/news/science-environment-21828202
Here's my count:
* General relativity describe the universe's dynamics quite accurately, been around for almost a century
* Dark matter has been around for 80 years (http://en.wikipedia.org/wiki/Dark_matter)
* Dark energy was discovered in the 1990's (super cool, but current measurements put it in the vanilla category).
* ns != 1 (support for inflation) detected by WMAP, verified by Planck. The idea of inflation comes from the 1980's.
* Inflationary gravitational waves discovered but turned out to probably be dust (http://www.bbc.com/news/science-environment-31058529)
