v0.22.0-M6

Includes all the changes of v0.21.21.

http4s-core

Breaking changes

• #4588: Additional consistency in modeled headers around .value (removed in favor of the typeclass) and .parse (present on the companion)
• #4580: Rename Uri.Path.fromString to Uri.Path.unsafeFromString.
• #4581: Rename Query.fromString to Query.unsafeFromString.
• #4602: Remove ipv4 and ipv6 macros that clash with ip4s'.
• #4603: Drop deprecated members of org.http4s.util.
• #4604: Fix rendering of UTF-8-encoded Content-Disposition parameters. The parameters map is now keyed by a CIString.
• #4630: Use Typesafe Literally to implement the literal interpolators. This should have zero impact on user code, but does affect binary compatibility.

http4s-dsl

Breaking changes

• #4640: Change apply(Headers.ToRaw*) syntax to headers(Headers.Raw). The overload from 0.21 was ambiguous with the new header model in 0.22.

http4s-boopickle

Breaking changes

• #4590: Move implicits to org.http4s.booPickle.implicits._. The thinking is evolving here, and this is likely to be reverted before 0.22.0 final.

http4s-scala-xml

Breaking changes

• #4621: Revert the implicits decoding back to how it was in 0.21. Set up safer defaults for the default SAXParserFactory, corresponding to what will be in scala-xml-2.0.
