Do-not-track: a pointless header that anybody who WOULD be inclined to track you would ignore. I don't see any value in this header, it does NOTHING to improve privacy. What would be a nice addition to the android version would be, rather than this pointlessness, PRIVATE BROWSING (no storage of cache/history/cookies/anything to device).
Does anyone with half a brain really care about the version number? The added features are far more important.
Typically, the version number step implies the number and/or significance of added features. A big version step implies a lot of significant changes, a small version step implies a few less significant changes. They made a BIG version step for insignificant feature changes, hence the clarification I added regarding the version numbering -- so that people who ARE expecting big changes due to such a big version number change won't all bother rushing out to update to something that really isn't significantly different. There WILL be a LOT of people who will take this update and be really disappointed that nothing has really changed.
