Decision made to maintain choice 2.7x core rather than somewhat buggy 2.8x-2.9x cores. That's why you will see infrequent and less bug fixes than official branches. All the features of 2.8x-2.9x (except rename). Run this solid 2.77+ port for extended days, it doesn't crash or lock. Prime for seedbox use. The included remote GUI port is fine tuned to the daemon released here. Temporary piece support. https://trac.transmissionbt.com/ticket/532 plus many featured enhancements! Tested, stable enhancements user requested. Specifically modified and bug tested for Linux GCC and Windows (cygwin gcc/g++) compilers.
