0.11.1 Release notes
0.11.0 Release notes
====================
Darkcoin Core 0.11.1 supports a full implementation of InstantX, Darksend improvements
and a new version of enforcement compatible with the newer Bitcoin architechure.
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. This list is compiled from the release
notes of Bitcoin Core 0.9.0, 0.9.1, 0.9.2, 0.9.2.1, 0.9.3 and was completed
with the introduced changes to the Darkcoin Core 0.11.0.
- Fully implemented IX
- Added support for DSTX messages, as a result DS should be much faster
- Clear vValue in SelectCoinsMinConf - should fix an issue with conflicted txes
- "Debug window" -> "Tools window" renaming
- "Last Darksend message" text added in overview page
- Many new languages are supported, such as German, Vietnamese, Spanish
- Fixed required maturity of coins before sending
- New masternode payments enforcement implementation
- Added support to ignore IX confirmations when needed
- Added --instantxdepth, which will show X confirmations when a transaction lock is present
- fix coin control crash https://github.com/bitcoin/bitcoin/pull/5700
- always get only confirmed coins by AvailableCoins for every DS relative action
