Release Pulling a fast one · sagebind/isahc

This release contains some minor performance improvements as a result of some internal changes.

Changed

Switch agent from curl-provided select(2) backend to polling. This delivers some throughput improvements in some benchmarks involving concurrent requests. This also removes Isahc's reliance on loopback UDP sockets for selector wakeups. (#17, #243, #263) @sagebind
Refactor request configuration internal representation. This offered a minor performance improvement in some cases by greatly reducing the amount of hashmap lookups needed for applying request configuration. (#292) @sagebind
