  New issue type, PhanTypeInvalidConstantName, emitted when the dynamic constant name cannot be a string. #4963
• Add basic support for deep-cloning of readonly properties
  in PHP >= 8.3. #4962

Bug fixes:

• Fix type inference for properties with a PHPDoc type of static in assignments #4883
• Fix type inference for json_decode returning objects vs associative arrays #4745
• Fix infinite loop detection with calls to openssl_error_string, ob_get_level, and error_get_last #4971
• Do not emit PhanPossiblyInfiniteRecursionSameParams if an array element or object property was modified #4972
• Do not treat non-empty-string as a subtype of callable-string. Treat callable-array as a subtype of non-empty-array #4974
• Properly infer template types when analyzing property assignments #4987
• Fix edge cases when parsing generic types #4992
• Do not infer all iterator key/value types from PHPDoc as real types #4986

Miscellaneous:

• Update PHP >= 8.1 signatures of internal functions for resource to object migration #4960
• Emit PhanTypeInvalidDimOffset when accessing a string offset of a union type containing string #4709
• Mark imap_header() as removed in PHP 8.0
• Infer key/element types more accurately for callable-array #4977
• Infer parameter default type more accurately #4398

Plugins:

• Fix PHPDocToRealTypesPlugin suggesting union types containing mixed as a non-standalone type #4952

  This only warns if all the @param are redundant, and does not flag individual redundant parameters. #4955
• Make UseReturnValuePlugin not require using the return value of similar_text when the &$percent argument is passed. #4979 #4981
