<p>The following blocks were abandoned (along with a few more along that chain as the quickly dwindling set of 0.8.0 miners plugs along) when the 0.7 blockchain caught up with the 0.8.0 blockchain at 2013-03-12 06:19:32.  Thankfully, you can see that the 0.8.0 chain has slowed down to just one block in the two hours after 03:28:41 UTC.</p>

<p>Also note that, as I understand it, most transactions are showing up in both blockchains.</p>

I suppose it would be more accurate to say "what block hashes" were discarded, since block numbers are "reused", and a block hash is always unique

Thankfully, you can see that the 0.8.0 chain has slowed down to just one block in the two hours after 03:28:41 UTC.

Also note that, as I understand it, most transactions are showing up in both blockchains.

Source: <https://blockchain.info/blocks/1363065244022> (where the ones to abandoned were labeled "Main Chain" until the current "Orphaned" chain caught up, at which point the labels swapped)

**Update**: I added 7 more blocks since the 0.8.0 chain was abandoned, up to 225461. The rate of continued mining there is a bit less than one block per hour.

**Update 2**: As of another day later, there haven't been any more blocks in the orphaned chain. There is only one block at height 225462 (<http://blockchain.info/block-height/225462>) so the orphaned chain may end at [a record](https://bitcoin.stackexchange.com/q/3343/99) 32 blocks.
