I do not recall seeing this announcement on the Flex Community yet. I strongly recommend that FT8 users upgrade to this release candidate as it is much improved over rc1.

Subject: [wsjt-devel] WSJT-X Version 1.8.0, Release Candidate 2
The WSJT Development Group is pleased to announce a second candidate
release of WSJT-X Version 1.8.0. Once again this is a beta release.
Most changes since the "RC1" release candidate are related to the FT8
mode, and most new features have already been tested in the field by
several hundred users.
Implementation of FT8 and its auto-sequencing feature is now more
capable and more polished. The decoder is faster and better: it now
includes signal subtraction, multi-pass decoding, and the use of
accumulated "a priori" information as a QSO progresses. Sensitivity
extends downward as far as -24 dB in some circumstances. Overlapping
signals 2 and 3 deep are frequently decoded at essentially the same
frequency. On a crowded band we sometimes see more than 30 decodes in a
single 15-second interval, over a 2 kHz window. The North American VHF
Contesting Mode has been extended to include both FT8 and MSK144 modes.
The "RC2" release also includes many minor bug fixes and an extensively
updated WSJT-X User Guide.
We strongly recommend that all WSJT-X users should upgrade to this new
