So, what's up? The original plan was to prepare a hard fork and release v0.7 with it. However it appeared more challenging and time consuming than expected, so my back-up plan was to release a maintenance update on the v0.6 branch to keep up with the progress. After all, the v0.6.6.2 release is 5 years old, though still functional. The last commit to the v0.6 branch is almost 3 years old, and this code base cannot even be compiled as it is on modern Linux distros with their default compilers and libraries. On the other hand, v0.7 beta does. It also offers better performance and functionality. So, the current plan is to release v0.7 without a hard fork scheduled and retire v0.6 entirely, though it can be used still. I'm going to merge the last bit of code from the v0.6 branch to v0.7 which is advanced checkpointing, also apply a few minor patches and make a release by the end of week. If you have any suggestions about v0.7, what should be added or fixed, let me know.
