full diff: https://github.com/emicklei/go-restful/compare/v2.9.5...v3.7.3 - Switch to using go modules - Add check for wildcard to fix CORS filter - Add check on writer to prevent compression of response twice - Add OPTIONS shortcut WebService receiver - Add Route metadata to request attributes or allow adding attributes to routes - Add wroteHeader set - Enable content encoding on Handle and ServeHTTP - Feat: support google custom verb - Feature: override list of method allowed without content-type - Fix Allow header not set on '405: Method Not Allowed' responses - Fix Go 1.15: conversion from int to string yields a string of one rune - Fix WriteError return value - Fix: use request/response resulting from filter chain - handle path params with prefixes and suffixes - HTTP response body was broken, if struct to be converted to JSON has boolean value - List available representations in 406 body - Support describing response headers - Unwrap function in filter chain + remove unused dispatchWithFilters Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
