What's new in version 2 of Block header message ?

The version field in block header message is now '2'.
Does someone know what is the difference compared to version 1?
Thanks

95% rule ("Point of no return"): If 950 of the last 1,000 blocks are version 2 or greater, reject all version 1 blocks. (testnet3: 75 of last 100)
Are we here yet on mainnet?

Yeah - At block 227930, the previous 1000 contained the supermajority of 950.

Very cool
Thank you for taking the time to look that up.

Anyway, this is not an information we can rely on.
I notice many blocks pretending to be version 2 but showing bad height encode values
See
http://blockexplorer.com/block/00000000000005d024e86337ca13439b7f3dbd5e1a005b1dbe510150d45b6e98
is block 200433 and pretends to be 436591499

is block 199914and pretends to be 436591499
May be such blocks must not be accepted by the network as the BIP34 is now enforced?

Early on, there was some debate about the proper encoding. See
this discussion
for information on why the bogus encodings were allowed (specifically a post from gmaxwell on July 2nd).

I routinely ignore posters with paid advertising in their sigs. You should too.

Do you mean that some miners start building v2 blocks on main network while the debate was not closed?

For something like this, a supermajority of miners have to move in lockstep, or there is risk of forking.

After block 227930, it's information you can rely on.
