Version 2.2 Change log:

  • Upgraded the staking system and improved staking efficiency.
  • Updated QT to 5.9.7. This can fix the Mac version start-up problem for Mojave and High Sierra users. It also means that Bitcoin 2 Core software starting with v2.2.0 will no longer run on MacOS versions older than Yosemite 10.10.
  • Upgraded depends.
  • Fixed a rare wallet crash scenario that could have happened while staking if one was beaten to the block and validating their created block.
  • Removed Qt4 build support and code fallbacks.
  • Fixed missing block explorer icon.
  • More than 99 confirmations will be required before coins can be staked.
  • If all other conditions are met, staking now begins after the wallet receives its first coins that can be staked without having to restart the wallet.
  • Changed the minimum transaction fee to 0.00003200 BTC2 per KB.
  • Removed explicitly unused transaction comparators that sometimes could have caused transaction timestamp display issues.
  • Completed the changes to claiming from the fork.
  • Started using the clock5.png icon when a transaction is almost confirmed.
  • Security improved.
  • Minor optimizations.
  • Removed the stretched Windows installer icon.

Updating your Bitcoin 2 Core wallet to this version is mandatory. That includes upgrading all your Masternodes. After enough nodes have upgraded to this version, a new staking protocol will be activated and the old nodes that fail to upgrade their wallet before that will end up forking to the wrong chain. Estimated time of this protocol upgrade is between August 22 - August 25 2019. As soon as possible.

To update, you just need to download the archive, stop your wallet and let it fully shutdown, and then copy the executable files in the bitcoin2-bin folder to replace the ones you had installed already.

After upgrading your Masternode and your desktop wallet, you should go in the Masternodes tab on your controller wallet and click to Start the upgraded Masternodes.

Binaries for a couple of platforms that are less used are still to be compiled.

If you want to synchronize faster, you can download a blockchain snapshot with transaction indexing enabled from https://www.bitc2.org/snapshot-june-8-2019.zip (new snapshot coming soon)
If you choose to use that, read the ReadMe.txt that is included in the .zip file for instructions.

Version 2.1.5 Change log:

  • Updated almost all of the logos and icons to use our new logo.
  • Updated the help text of the RPC sendfrom and sendtoaddress commands.
  • RPC command sendfrom now only uses coins belonging to the account’s address, if the from account name is a BTC2 address.
  • RPC sendfrom - If account name is a BTC2 address, only check that the account has enough spendable coins.
    Removed the internal account balance check for that case, but if the account name is not a BTC2 address, the internal account balance check is still in place.
  • Added a range check to Zerocoin serial number.
  • RPC sendfrom - select minimal number of UTXOs. - Ensured that coin selecting stops when enough coins have already been selected.

Updating to this version is highly recommended.

Version 2.1.4 Change log:

  • Lowered minimum Swift TX feature's fee from 0.01 BTC2 to 0.00050000 BTC2. This fee change will only take effect after enough masternodes update to v.2.1.4 or newer.
  • RPC sendfrom command can now optionally send as a Swift TX and will no longer use funds from other accounts in the same wallet if the transaction fee + amount would total more than the amount in the account’s balance. Also, now if account name is a BTC2 address, change is sent to that address.
  • RPC listtransactions fix: Write new transactions to wtxOrdered properly.
  • Allow passing change address as string to CreateTransaction().
  • RPC importprivkey command now returns the public address on success and sets the public address as the label if “$pub” is passed to it as the label.
  • A few RPC commands reported wrong values for account/label balances after staking with a wallet. This has now been fixed at least when there are no internal transfers (without a corresponding transaction in the blockchain) between accounts on the same wallet but as a result the following RPC commands now work differently than before and will display different values than before:
    ... listtransactions
    ... getbalance "account"
    ... listaccounts (You can use this legacy function to check accounts/labels, but not balances.)

Updating to this version is recommended but optional.

Version 2.1.3 Change log:

  • Removed v.2.1.1 debug logging that caused a crash on start-up on fresh installations (when no blocks had been downloaded yet).
  • Fixed: Occasionally a staking node with a sometimes unstable or slow network used to get stuck on its own chain for up to 2 hours.
  • Less kernel debug logging unless asked for.

Note: You would need to install the previous version and run it before you can use this version. This was fixed in the 2.1.3 version.

Version 2.1.1 Change log:

  • Added a secondary DNS seeder and updated the fixed seed nodes.
  • Sometimes when trying to spend zBTC2, the coins were not able to be selected automatically. That has been fixed.
  • Removed some unnecessary debug logging.
  • changed MAX_BLOCKS_IN_TRANSIT_PER_PEER from 16 to 44.
  • zBTC2 autominting is now ensured to be disabled by default.
  • Updated the QT wallet’s “Pay only the minimum fee” feature to use the actual current minimum fee.
  • Options – Preferred automint denomination and debug commands now display the zBTC2 denominations in BTC2 instead of in cents.

Version 2.1b Change log:

  • If you were stuck syncing block 6538 or lower, this newly uploaded release fixes that problem.

Version 2.1.0 Change log:

  • The bug that caused the crash after block creation in some scenarios was fixed.
  • Zerocoin denominations smaller than 1 zBTC2 can now be spent and they are displayed correctly in the privacy dialog.
  • Each unspent mature output now gets a higher chance of being staked in order to create a block. (25 chances instead of 1 per attempt.)
  • Minimum staking difficulty is now easier.
  • Difficulty is now adjusted every 10 blocks instead of every block. This makes the adjustments smoother and aims better at the 1 block per minute target.
  • Immature balance is now deducted from the displayed available balance. (Display change only.)
  • If a user typed zBTC2 spend would be only a few satoshis away from a denomination, the amount gets rounded now to the closest denomination.
  • DNS Seeder address added.
  • Port was changed to the same port that Bitcoin uses. 8333

The Mac version will be released later.
