Dogecoin Core 1.7.0 released - Check in here for all info you need

Hi shibes!
The Dogecoin developers are proud to announce the final version of Dogecoin Core 1.7! After lots of coding, testing and swearing this is the next version of our reference client. It brings Dogecoin one big step forward on the technical side of things, with moving to the Bitcoin 0.9 codebase.
The full release notes are available here: https://github.com/dogecoin/dogecoin/releases/tag/v1.7.0
TL;DR of the release notes
Is this mandatory? No, you can stay on 1.6 if you want for now. This update adds quite a few new features you'd miss out on.
How to update?
  1. Backup your wallet! This is very important! Go to File -> Backup Wallet, and save this file in at least two safe places for a good backup.
  2. Exit the client you're running now.
  3. Install the update
    1. For Windows, use the setup.exe to update. If you are using the new 64bit version you'll need to uninstall 1.6 afterwards.
    2. For Mac just overwrite the version you currently have in you Applications folder.
    3. For Linux you'd overwrite your current dogecoin-qt binary with the new one.
  4. Start the client. That's it :)
About going back to 1.6 Once you go to 1.7 there is no easy way back to 1.6. That's why it's important to have a backup of your wallet. Just in case. Be aware that a backup goes out of date after 100 transactions! Several people have been running 1.7 for a while now and see no problem with it, so you probably don't want to go back anyway ;)
Downloads (Listing here this time to make it easier to find)
Changes from RC1
Staying up to date If you want to easily stay up to date with releases, you can subscribe to the mailing list right here: http://sourceforge.net/p/dogecoin/mailman/dogecoin-releases/ That's especially advised if you are a service provider!
General comments For anyone running an exchange, please also note that in light of the 51% attack against Reddcoin last night, the Dogecoin developers now recommend a minimum of 10 confirmations for payments into an exchange.
Thanks Thanks to everyone who contributed so far! Especially leofidus-ger, rnicoll and patricklodder, who have done by far the most of the work for this release. But of course thanks to everyone else who contributed, may it be advice or code or whatever. Also thanks to the Bitcoin developers. And of course thanks to the Dogecoin community! You are what makes it fun to work on all this ;)

Armory Problems on Mac

Been running Armory on a Mac (10.9.2) and it's not going well. Armory will open, then spend an inordinate amount of time updating it's database. I get the "Armory is Online!" (starting to get really annoyed with the exclamation point) but then all joy is lost.
I try to send a payment and Armory either crashes or notifies me that there are "invalid blocks" or that Bitcoin QT is offline. Bitcoin QT is on the current block with a happy green check.
I liked Armory when it was functional, but at this point, I'd really like to clear out the wallet until Armory is updated and the bug fixed. I've sent a couple of emails to Armory about the problem, (2 weeks ago) and not received any response. In my case, it's just a few millibits, but I'd have a hard time recommending it to anyone on a Mac.
Anybody else have this problem and found a solution? I do have the paper backup for the wallet, so maybe uninstall/reinstall?
A little disappointed that there has been no assistance from Armory. Maybe some reddit exposure may get a response.
tl;dr Armory no worky on Mac 10.9.2.

Bitcoin-QT 0.9 disponível para download

The Core Developers of Bitcoin released the 0.9.0 FINAL of Bitcoin Core (aka Bitcoin QT).
DOWNLOAD:
This is a Final Version, but its the same as 0.9.0rc3
Sources: https://github.com/bitcoin/bitcoin/releases http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.9.0/ https://bitcoin.org/bin/0.9.0/README.txt
Bitcoin Core version 0.9.0 is now available from:
https://bitcoin.org/bin/0.9.0/
This is a release candidate for a new major version. A major version brings both new features and bug fixes.
Please report bugs using the issue tracker at github:
https://github.com/bitcoin/bitcoin/issues

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), uninstall all earlier versions of Bitcoin, then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).
If you are upgrading from version 0.7.2 or earlier, the first time you run 0.9.0 your blockchain files will be re-indexed, which will take anywhere from 30 minutes to several hours, depending on the speed of your machine.
On Windows, do not forget to uninstall all earlier versions of the Bitcoin client first, especially if you are switching to the 64-bit version.

Windows 64-bit installer

New in 0.9.0 is the Windows 64-bit version of the client. There have been frequent reports of users running out of virtual memory on 32-bit systems during the initial sync. Because of this it is recommended to install the 64-bit version if your system supports it.
NOTE: Release candidate 2 Windows binaries are not code-signed; use PGP and the SHA256SUMS.asc file to make sure your binaries are correct. In the final 0.9.0 release, Windows setup.exe binaries will be code-signed.

OSX 10.5 / 32-bit no longer supported

0.9.0 drops support for older Macs. The minimum requirements are now: * A 64-bit-capable CPU (see http://support.apple.com/kb/ht3696); * Mac OS 10.6 or later (see https://support.apple.com/kb/ht1633).

Downgrading warnings

The 'chainstate' for this release is not always compatible with previous releases, so if you run 0.9 and then decide to switch back to a 0.8.x release you might get a blockchain validation error when starting the old release (due to 'pruned outputs' being omitted from the index of unspent transaction outputs).
Running the old release with the -reindex option will rebuild the chainstate data structures and correct the problem.
Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan the blockchain for missing spent coins, which will take a long time (tens of minutes on a typical machine).

Rebranding to Bitcoin Core

To reduce confusion between Bitcoin-the-network and Bitcoin-the-software we have renamed the reference client to Bitcoin Core.

Autotools build system

For 0.9.0 we switched to an autotools-based build system instead of individual (q)makefiles.
Using the standard "./autogen.sh; ./configure; make" to build Bitcoin-Qt and bitcoind makes it easier for experienced open source developers to contribute to the project.
Be sure to check doc/build-*.md for your platform before building from source.

Bitcoin-cli

Another change in the 0.9 release is moving away from the bitcoind executable functioning both as a server and as a RPC client. The RPC client functionality ("tell the running bitcoin daemon to do THIS") was split into a separate executable, 'bitcoin-cli'. The RPC client code will eventually be removed from bitcoind, but will be kept for backwards compatibility for a release or two.

walletpassphrase RPC

The behavior of the walletpassphrase RPC when the wallet is already unlocked has changed between 0.8 and 0.9.
The 0.8 behavior of walletpassphrase is to fail when the wallet is already unlocked:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 Error: Wallet is already unlocked (old unlock time stays) 
The new behavior of walletpassphrase is to set a new unlock time overriding the old one:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 walletunlocktime = now + 10 (overriding the old unlock time) 

Transaction malleability-related fixes

This release contains a few fixes for transaction ID (TXID) malleability issues:

Transaction Fees

This release drops the default fee required to relay transactions across the network and for miners to consider the transaction in their blocks to 0.01mBTC per kilobyte.
Note that getting a transaction relayed across the network does NOT guarantee that the transaction will be accepted by a miner; by default, miners fill their blocks with 50 kilobytes of high-priority transactions, and then with 700 kilobytes of the highest-fee-per-kilobyte transactions.
The minimum relay/mining fee-per-kilobyte may be changed with the minrelaytxfee option. Note that previous releases incorrectly used the mintxfee setting to determine which low-priority transactions should be considered for inclusion in blocks.
The wallet code still uses a default fee for low-priority transactions of 0.1mBTC per kilobyte. During periods of heavy transaction volume, even this fee may not be enough to get transactions confirmed quickly; the mintxfee option may be used to override the default.
