In this information i see certain contradictions and assume that they are wrong:
- 6x0 and 11x0 SMB appliances are officially supported until June 2022
- 1200R has no End of Support date yet and should be supported until 2014 at least
On the other hand, we know the last available firmware version for older models:
- SG-80: fw1_dep_R75_983004120_20.img = R75.20.71 Build 983004120
- 6x0 / 11x0: fw1_dep_R77_990172487_20.img = R77.20.80 Build 990172487
- 1200R: fw1_ind_dep_R77_990172583_20.img = R77.20.81 Build 990172583
Afaik, there may be new builds of R77.20.80/81 if they are absolutely needed to fix important bugs or vulnerabilities.
So, R77.20.xx MUST be supported until June 2020 anyway...
