Announcing MMGen version 0.8.5New features/improvements:- Colored output
- Label editing in mmgen-txcreate
This release includes a major object-oriented overhaul of much of the code, which will make MMGen easier to develop and maintain. NOTE: The transaction file format has changed. Since TX files are temporary, this shouldn't be a problem for most. However, the script 'tx-old2new.py' in the scripts directory will convert old old TX files to the new format for those who need to do so. The Windows implementation is functional again. Use at your own risk, and report any problems on the Bitcointalk forum. A prebuilt bootable image with version 0.8.5 is available on the MMGenLive project page.

Announcing MMGen version 0.8.6New features/improvements:- Address generation using the secp256k1 library (Linux only)
Instructions for installing the secp256k1 library on your system have been added to the wiki. If secp256k1 is not installed on the system, MMGen still remains usable. It just falls back to 'keyconv', or failing that, python-ecdsa for generating addresses. A prebuilt bootable image with version 0.8.6 is available on the MMGenLive project page.

Announcing MMGen version 0.8.7 New features/fixes/improvements: Testnet support:- Practice sending/receiving coins without risking real funds. (Get free testnet coins at https://tpfaucet.appspot.com/)
- Test suite fully supported
- To enable, set MMGEN_TESTNET environment variable and restart bitcoind with the -testnet option
Fixes/enhancements:- The regression preventing importing addresses with --rescan has been fixed
- Tracking and spending non-MMGen addresses is now fully functional. All the scripts correctly recognize and display non-MMGen addresses
- mmgen-txcreate: improvements in unspent outputs display
- mmgen-txsign: use bitcoind wallet dump as keylist without modification
A prebuilt bootable image of version 0.8.7 is available on the MMGenLive project page. MMGen project page: https://github.com/mmgen/mmgenMMGenLive project page: https://github.com/mmgen/MMGenLiveSupport the MMGen project: 15TLdmi5NYLdqmtCqczUs5pBPkJDXRs83w

Announcing MMGen version 0.8.8 Data directory, config file and default wallet support:- Data directory is '~/.mmgen'; config file is 'mmgen.cfg'.
- When default wallet is present in data directory, specifying the wallet on the command line is optional.
- Datadir structure mirrors that of Bitcoin Core: mainnet and testnet share a common config file, with testnet putting its own files, including the default wallet, in the subdirectory 'testnet3'.
- Global vars are now overriden in this order:
1) config file 2) environmental variables beginning with 'MMGEN_' (listed in globalvars.py) 3) command line - Long (common) opts added for setting global vars; display with --longhelp.
The test suite has been updated to test the new features. Tested on Windows: the stable_mswin tag now points to this release. Other changes/improvements:- Always get user entropy, even for non-critical randomness, unless '-r0'.
- rpcuser,rpcpassword now override cookie authentication, as with Core.
- Communication with remote bitcoind supported with --rpc-host option.
- Testnet use can be set/overridden with the --testnet=0|1 option.

Downloading a copy of the live boot image to try tonight. I unfortunately run a custom bitcoind based on 0.5.4 so can't use it under my daily driver. But project looks very nice and piqued my interest enough to give it a shot. Kudos for doing the right thing and signing the images as well. ![Cool](https://bitcointalk.org/Smileys/default/cool.gif)

Glad to hear it! I've tested it on a variety of hardware but never tried booting it in a virtual machine. At what stage did the graphics boot fail?

It allows me to decrypt fs, but when it gets to user login it just sort of "loops" there and allows no input. If I get a chance this week I will see if I can dump some debug information on it. The other method works fine however, so if there are users accustomed to command line that want to give it a test drive, it's an option.

With qemu, install xserver-xorg-video-vesa and graphical boot will work! You'll get best performance with -vga std. These parameters work for me: qemu-system-x86_64 -vga std -m 1024 -enable-kvm -machine pc-q35-xenial,accel=kvm xenial64.img The screen resolution is incorrect. I'll see what I can do about that. I've discovered that the ~/bin directory isn't always getting added to $PATH. So you have to do it by hand, or run the scripts as bin/<scriptname>. These issues will be fixed by the next release.

What version of qemu are you using? I have QEMU emulator version 2.6.0 (Debian 1:2.6+dfsg-3.1) currently. I made need to build another from source as mine doesn't find the machine type. Adding the -vga-std flag did allow me to type in user this time, but still hangs upon entering pass. Not a big deal honestly, as I am used to working solely in cli. The minimalist in me will likely scrap the Lubuntu bits anyway and add mmgen to a gentoo image. The minipc thing is interesting as well. I was working with some guys on a pogoplug type box for this purpose though the insane memory requirements put a damper on it.

You should be booting right into an autologged-in X session, the screen you see in my writeup above. If not, then something's wrong. My host system is Ubuntu xenial, just like the boot image system: $ qemu-system-x86_64 --version QEMU emulator version 2.5.0 (Debian 1:2.5+dfsg-5ubuntu10.6), Copyright (c) 2003-2008 Fabrice Bellard $ qemu-system-x86_64 --machine help Supported machines are: ubuntu Ubuntu 16.04 PC (i440FX + PIIX, 1996) (alias of pc-i440fx-xenial) pc-i440fx-xenial Ubuntu 16.04 PC (i440FX + PIIX, 1996) (default) pc-i440fx-wily Ubuntu 15.04 PC (i440FX + PIIX, 1996) ... pc-q35-xenial Ubuntu 16.04 PC (Q35 + ICH9, 2009) q35 Standard PC (Q35 + ICH9, 2009) (alias of pc-q35-2.5) ... isapc ISA-only PC none empty machine xenfv Xen Fully-virtualized PC xenpv Xen Para-virtualized PC The Mini-PC's been up and online for about a week now, almost 24/7, without so much as a hiccup. I'm very satisfied so far. I'd been considering something more minimal, too, but having some experience running full nodes it became clear that Pogoplugs, Raspberry PIs, etc. just aren't up to the task anymore. MMGen on a Pi makes a good offline signing machine, but not an online node.

Announcing MMGen version 0.8.9This release brings full functionality and wider testing to the MS Windows port. MMGen now works with both WinXP/MinGW32 and Win7+/MinGW64, and separate, updated installation instructions for both platforms have been added to the wiki. A working MSYS/MinGW environment is now required to run MMGen under Windows. New Windows features:- Full non-interactive test suite support with pexpect (PopenSpawn)
- secp256k1 address generation support
- Secure wallet deletion with sdelete
Windows bugfixes:- A critical bug in writing the encrypted keyaddrfile has been fixed. This bug would have affected only online wallet use and would not have led to the loss of coins
- Cookie filename fixed; RPC cookie authentication now functional
General features:- --bitcoin-data-dir, --rpc-port, --rpc-user, and --rpc-password options
