• Optimized model scoping in JsonSchemaConverter by constructing through a
  Model.Builder instead of filtering shapes.

  (#3106)

Bug Fixes

• Fixed an issue where traits would lose their types, reverting to DynamicTrait,
  when renaming shapes
  (#3086)
• Fixed selector parsing to properly handle extraneous BREAK_TOKENS (',', ']',
  ')') in a selector. This manifested in silently dropping contents in the comma
  case ("structure, string" was effectively just "structure"). For the closing
  brace/paren, the characters were silently ignored as seen in the additional
  fixed tests. (#3063)
• Fixed event stream test params encoding blobs in b64.
  (#3121)
• Fixed a bug in OpenAPI conversions where onErrorStatusConflict from
  mappers/protocols wasn't being respected.
  (#3123)
• Fixed a Windows user PATH corruption in install.bat caused by setx silently
  truncating values over 1024 characters
  (#3117)
• Fixed an issue where jsonName wasn't applied to examples in OpenAPI for
  restJson1 (#3108)
• Fixed trait-codegen failure when string literals contain dollar signs
  (#3096)

Documentation

• Fixed stale and mismatched AWS API Gateway reference link targets
  (#3077)
