- Update to 1.4
- scheduler assigns jobs with larger priority first, so compilations with higher 'nice' value
do not interfere with normal compilations
- avoid large timeouts if there is a network problem
- support for -march/-mcpu/-mtune used with =native (proper specific flags will be substituted)
- support for Clang's -fmodules, by removing the -fmodules flag for remote compilation
- do not keep host lock when sending preprocessed source (reduces chance of network timeouts)
- send more jobs in advance to nodes with many CPU cores
- try to use larger network buffers
- force local compilations if --coverage is used
- correctly clean up caches
- handle properly the case when something removes files in the cache directory
