- New improved fee dialog for Darksent transactions
- Improved Darksend progress bar
- Darksend minimum requirement lowered to 1.5DRK
- Various improvements to Darksend, should work for almost any situation now

Start-Many Support

Github user freynder rewrote the start-many configuration file to tie specific inputs to specific masternodes, so the client would know
the correct ones to start. To use this functionality, simply make a ~/.darkcoin/masternode.conf with the following information.

0.11.0 Release notes
Darkcoin Core 0.11.0 is forked off the Bitcoin Core 0.9.3. The old darkcoin versions 0.10.x were forked from the Litecoin 0.8 tree. The following changes are introduced in this major release.

edit: still no connections, can't pick up any on local Linux 64 QT client either. Port 19999 open everywhere.

edit2: various build errors involving libdb4.8 and boost, yes I installed db4.8 as per instructions, will try on a cleam VM in case I've borked something on my laptop.

I can't get either the 32 bit or 64 bit windows QT executables to run. When execute I get an hourglass for a couple of seconds and then the process terminates without any message at all.

Any ideas?

same problem... was about to post

Also i'm curious what the darkcoin-cli.exe exactly does in windows 32bit or 64bit
darkcoin-qt immediately crashes under Win7 64 (both the 32 and the 64 bit versions of the client).

It doesn't even come to the point where it creates or accesses the default .darkcoin folder, so there's no debug.log.

My Bitcoin v0.9.3 client runs fine.

Edit: started it with the existing testnet blockchain (is it compatible with the current testnet?) and without it, no difference.

there was a problem with change min version to 70046 which has been fixed. i assume thats also causing the windows binaries failures...i suspect Evan is recompiling

Yeah, known issue from 0.10.x, crowning already fixed this. (Not related to v11 testing.)

Good find. Similar problem as last week with the RFC1918 addresses:


Edit: Thanks for this.
