Very nice! There have definitely been some major improvements, including the hashmeter, RPC support, and a command-line daemon. It would be nice if the listtransactions RPC method were finished before the next release, though. Also, some code should be added to the JSON-RPC methods to list out dHashesPerSec.

Great work Satoshi!

Should we try for some publicity? Slashdot is good if we can get it.

I've had a number of submissions accepted, though always by one editor that no longer works there. Anyone else with a Slashdot connection?

My fear is too many programmers would latch onto that for checking for received payments.  It can never be reliable that way.  The list/getreceivedbyaddress/label functions are the only way to do it reliably.

We shouldn't delay forever until every possible feature is done.  There's always going to be one more thing to do.

I just finished creating a clean Amazon EC2 debian 5.0 machine image with everything I needed to compile bitcoind, and it compiled (using a variation of Laszlo's makefile.unix) and is running fine (just finished downloading the block chain).  I'll let you know if it misbehaves.

I had trouble compiling the gtk version, but I think that's because I did something wrong compiling wxWidgets.  I don't need no stinkin' graphics (and am not a wxWidgets expert), so I'm not going to bother trying to fix that.

What operating system?

Normally when it does that it's because the directory where the data directory should go doesn't exist.  See if the "%appdata%" directory exists.

Do you get that error with 0.2 also?  It's hard to see how you could get that with 0.3 and not with 0.2 since there's nothing different in that regard.

davidonpda, were you also running laszlo's build previously?

Check if the "%appdata%" directory exists, and "%appdata%\bitcoin"

Try:
 rename "%appdata%\bitcoin" bitcoin2

does it work then?

You figured it out faster than I could post a reply.  

It looks like laszlo's build of Berkeley DB has database/log.* files that are not compatible with ours.  The .dat files are fine, their format shouldn't ever change.  All data is stored in the .dat files.  All your own data is stored in wallet.dat.  If you had waited for it to redownload the block chain, your missing transactions and generateds would have appeared as the block chain reached the point where those transactions were recorded.

When you copied the directory except log.0000000002, that's the best solution.  You should be good now.

The database/log.* files only contain temporary database data.  If you exited bitcoin normally the last time, not exited by forced terminating it or crashing, then the database/log.* files can normally be deleted safely.  They're only used so that if the database is in the middle of a transaction when the computer crashes or the program is killed or crashes, then it could recover without losing data.

Please keep running v0.3 if at all possible, don't go back to v0.2.10.

Anyone else who hits this problem, move the database\log.000000000* files somewhere else.  (if it works fine after that, you can delete them later)

I'm reluctant to make the installer delete or move those files.  If the previous run was stopped by crashing or killed, that would be the wrong thing to do.

Runs fine under WINE. *rhymes*

It automatically switched the language to German, too. Now that I can see the translation in the client itself, I noticed a few things to improve, and will post a new .po file within the next two or so days.

Laszlo figured out that enabling some more optimisation increased performance about 20%, so 0.3 hashes 20% faster than 0.2.0, but I assume he used that in his own build.

30khash increase to what total rate?  (to figure the % increase)
