httpuv 1.4.0

• Changed license from GPL 3 to GPL >= 2. (#109)

• Added IPv6 support. (#115)

• httpuv now does I/O on a background thread, which should allow for much better performance under load. (#106)

• httpuv can now handle request callbacks asynchronously. (#80, (#97))

• Fixed #72: httpuv previously did not close connections that had the Connection: close header, or were HTTP 1.0 (without Connection: keep-alive). (#99)

• Fixed #71: In some cases, compiling httpuv would use system copies of library headers, but use local copies of libraries for linking. (#121)

• Let Rcpp handle symbol registration. (#85)

• Hide internal symbols from shared library on supported platforms. This reduces the risk of conflicts with other packages bundling libuv. (#85)

• Fixed #86: encodeURI() gave incorrect output for non-ASCII characters. (#87)

• Fixed #49: Some information was shared across separate requests.

• Upgraded to libuv 1.15.0. (#91)

• Upgraded to http-parser 2.7.1. (#93)
