Mandatory Update
Critical bug fix for difficulty adjustment after hardfork block.
Summary
We've recently realized that our previous method for difficulty adjustment isn't sufficient when a hardfork occurs, especially if the hashrate drops significantly. Normally, the default difficulty adjustment window spans 2641 blocks, which are used to calculate the target difficulty. Previously, we reset the difficulty for the first 10 blocks following a hardfork, but by block 11, the difficulty reverted to almost the same level as before the hardfork. This situation necessitates rebuilding all releases, making it a mandatory update. Although this remains a single hardfork since we are still before the HF DAA score of 26962009.
