The "problem" is somewhere else.
v0.8.6b was not a public update and the changelog states changes between the two last public main updates aka v0.8 and v0.9 (and come on... "from v0.8" is written 4 times...maybe 5 times was needed after all^^)
Also by reading the v0.8.6b changelog, it seems pretty clear what the contents of the v0.9 were going to be.
I can understand it is frustrating that your favorite paths did not get additional content this time, but I can also say that you were lucky to play those paths "in advance" during the v0.8.6b (beta) instead of the v0.9 like the rest of the paths
