ANONCOIN NEW VERSION 0.9.6.12 RELEASED - 12 OCTOBER 2016 - HARDFORK @ BLOCK 585555

We announce the official release of the new master based on Anoncoin 0.9.6.12.

This new version (v0.9.6.12-3fd47af) is an obligatory update of Anoncoin with an HARDFORK @ block 585555

Featured changes in this version are the following:

Difficulty algorithm tuned:
- PID tuning to make diff adjustment less aggressive:
      NMAXDIFFINCREASE "200" -> 150 (less difficulty increase, to avoid huge spike in diff)
      NMAXDIFFDECREASE "170" -> 130 (less difficulty decrease, to avoid lots of easy mined block)
      DMININTEGRATOR 170 -> 176 (less difficulty increase on long term because it is not needed as testnet showed)
      DMAXINTEGRATOR 190 -> 195 (more difficulty decrease as we have seen multipool jumping on/off in long term slow the blockchain)
      WEIGHTEDAVGTIPBLOCKS_UP 4 -> 9 (taking more blocks into the average up slow down diff increase and avoid huge spike in diff)
      WEIGHTEDAVGTIPBLOCKS_DOWN 6 -> 20 (taking much more blocks into the average down slow down the difficulty decrease and hence avoid too many easy blocks in a row)
      PID_PROPORTIONALGAIN 1.7 -> 1.6 (reduce aggressiveness of proportional term)
      PID_INTEGRATORTIME 172800 -> 129600 (integral term of 1.5 day to adjust quickly to abnormal number of emitted block)
      PID_INTEGRATORGAIN 5 -> 8 (the integral term now has more weight in the difficulty calculation, the ranges are respectively of (180-176)*8=32 vs 50 for difficulty going up and of (195-180)*8=120 vs 50 for difficulty going down. So compared to the previous settings, the difficulty can adjust more readily to a slow blockchain to achieve 180 sec avg per block.)
     PID_DERIVATIVEGAIN 0 -> 3 (adjust quickly to change of block time ie at apex of difficulty it will drop quicker, and at lowest turn up quicker)

- Auto-adjustment of difficulty via getblocktemplate to a low one if no block is found in 30 minutes

- The difficulty is now expressed again into a positive >1 number, because people and services complained of 0-1 range

- Blockchain synchronization issues fix (in case no block is found for a long time because of miner exodus, mining will be allowed up to one week old unsynchronized chain)

- Bug because of toolchain build of protobuf solved


Old version featured the following:

- Full I2P-SAM support
- An upgraded to bitcoin 0.10.99 code
- Many excellent improvements such as for instance header-first synchronisation, leading to much quicker I2P synchronisation and block download
- Deterministic fork selection
- A rewritten communication protocol (I2P and clearnet)
- No more using IRC for synching peers
- Anoncoin's test network (testnet) and regression test mode (regtest) available
- A new Kimoto Gravity Well v 2.0 using curves that is much quicker to calculate (it will be useful only for blocks before the hardfork and for first synching as KGW will be obsoleted by PID)
- A second new innovative difficulty algo "GroundRod RetargetPID" using a PID (Proportional - Integral - Derivative) controller, that will be enforced at block 555555 as the new difficulty retargetting system
- Real hashes calculation and not pseudo difficulty (we will be the only Scrypt coin to use true hashes in calculus of difficulty)
- Multisig Anoncoin address
- An improved mining through I2P only, to go forward a fully I2P darknet coin
- Themes support in anoncoin-qtt (currently for Win32, OS-X and linux, not for win64)
- SAM support ported to 0.10.99 and working with both Java and C++ implementation of I2P (Orignal's i2pd, LibI2Pd)
- New I2P and DNS seednodes
- Headless building with toolchain
- New alert key management
- Auto generation of I2P addresses provided the java I2P router is configured with default options during setup
- Bug fixes

Every Anoncoin user shall update to this 9.6.12 version ASAP. This is a mandatory upgrade, as after block 585555 the old peers will be disconnected. The version 9.6.11 will be obsolete when the HARDFORK block 585555 will be mined. This will occur the 27 October or in about 2 weeks.

Special thanks to our developers and long term fans: Meeh, K1773R, BroTroxer, Gnosis, Lunokhod, Cryptoslave, GroundRod, Mrebum, Abyss, Ssuag, Orignal, Alacast, Geekz, N00n & all others

This build could not have been done without the long term commitment and excellent work of GroundRod who updated all the codebase to 0.10.99, developed the difficulty retarget algorithm GroundRod PID, reworked SAM support, reworked the communication protocol, implemented the regtest mode, developed a new alert key management, worked on the test suites and implemented the toolchain build.
