v0.18.0: Retract v0.50.0

Compare Source

Echo 5 support was introduced in this repository with the v0.50.0 release. However, this also means that users who are still on Echo 4 and run go get -u ./... will inadvertently pull in Echo 5, which they neither want nor need at this time.

v0.50.0 will be retracted in v0.18.0 series and v0+ will only support Echo 4.
For Echo 5 support use v5 major version of this repository.

Full Changelog: labstack/echo-contrib@v0.17.4...v0.18.0

Relates to #​142
