Version 0.3.10 patches the block 74638 overflow bug. &nbsp;&nbsp;http://www.bitcoin.org/smf/index.php?topic=823

The Linux version includes tcatm's 4-way SSE2 SHA-256 that makes generating faster on i5, i7 (with hyperthreading) and AMD CPU's. &nbsp;Try the "-4way" switch to enable it and check if it's faster for you.

It is no longer necessary to delete blk\*.dat. &nbsp;The good block chain has overtaken the bad block chain, so you can just upgrade and it'll automatically reorg away the bad block chain.
