Dogecoin Core 1.10 beta 2Dogecoin 1.10 is a complete rebuild based on Bitcoin 0.11. This means in terms of the code-base we introduced all the changes between Bitcoin 0.9 and 0.11 into this version of Dogecoin Core.
We therefore suggest to read the release notes of both
Bitcoin 0.10 and
Bitcoin 0.11Beta 2 introduces a number of bug fixes and improvements since beta 1:
* Correct AuxPoW support checks to match Dogecoin Core 1.8 rather than Namecoin
* Correct and expand RPC unit tests
* Add NODE_BLOOM service bit
* Fix missing new line in error messages
* Update testnet checkpoints so syncing is smoother, and add DNS seed
* Correct incompatibilities in fee calculation code compared to Dogecoin Core 1.8
* Remove old Bitcoin release notes
* Replace further references to Bitcoin with Dogecoin where user-facing
* Use locale-specific number formatting instead of thin spaces as thousand-separator in numbers
UpgradingTo upgrade from any version below 1.10 you will need to re-index once, as the block database format has changed. If you run the Qt GUI client, it will prompt you to do so on the first start after the update. If you run a dogecoind daemon, you will need to start it with the parameter `-reindex` once after you updated. This process can take a few hours, depending on the performance of your machine.
Notable changesFor further explanation of these, see the above mentioned Bitcoin release notes.
Faster synchronizationDogecoin Core 1.10 introduces headers-first and parallel block synchronization to greatly reduce the initial blockchain synchronization time.
Watch only address supportIt is now possible to add public keys to your wallet that will be held in a "watch only" state. This means you will get information about incoming/outgoing transactions and resulting balance changes. Especially useful to keep track of your paper wallets.
Strict signature encoding (BIP66)One of the reasons why mining is disabled on this release is the introduction of [BIP66](
https://github.com/bitcoin/bips/blob/master/bip-0066.mediawiki) which enforces strict rules about how transaction signatures are encoded and therefore will introduce a new block version (3). These rules will only activate once a certain number of blocks are mined with this new version. To not let this happen too early, mining is disabled for now. NOTE: This is **not** a hard fork, as all existing wallets will accept version 3 blocks, although they'll fail to enforce the new requirements.
Block file pruningIt is possible to run a Dogecoin node without keeping the full blockchain on your disk. This is currently incompatible with having a wallet on that client due to the fact that some actions regarding a wallet require the full block data. The minimum amount of kept blocks has been changed from Bitcoin to reflect our shorter block times.
General commentsPlease backup your wallet regularly and especially before performing this upgrade. Do not copy your wallet.dat while Dogecoin Core is open. Instead you should either use the backup feature you find in the "File" menu or shut down Dogecoin Core completely before you make a copy of your wallet.dat.
