⚠️ WARNING ⚠️ - behavior change

This release includes a change to the default behavior of HTTP clients - we improved our compliance with Smithy's standard on path-encoding, but we accidentally changed the default behavior instead of making it opt-in, in #1668.

See #1792 for more detail.

What's Changed

• codegen: Add support for bincompat-friendly code generation mode in #1737 + #1780.
• core: fix #1663 by reworking how path segments are encoded to conform with the Smithy spec in #1668
• aws-http4s: fix AWS request signing for URIs with encoded path segments in #1668
• json: support open lenient unions, fix #1713 in #1782

Other changes

• Run protocol publishLocal with a cache by @kubukoz in #1783
