Not too many changes in this release. The major change is that I re-enabled CONFIG_USE_MKLIBS, enabling library strip again. I didn't wanted to do that, however I think that the small /overlay space from the last release has responsible for one issue that I had (sometimes the Wi-Fi stopped working completely, and even a reboot wouldn't solve it). I am still testing if this issue is solved, though.
Since CONFIG_USE_MKLIBS=y again, /overlay increased to 384KB and there is no support for opkg installed applications. This release is pretty similar to 1.9.X_m2, just less random changes.
One new thing: I included images for TL-WR740n-v5, TL-WR740n-v6 and TL-WR741nd. Not tested, however the hardware should be similar to the rest of TL-WR74X family, and I know one succesful flash of the previous version in a TL-WR740n-v5.1 router.
Finally, one small fix: /etc/banner should include correct Gargoyle revision, instead of HEAD ID from this repository (that always change, since I always rebase from upstream).
