:bug: Bug Fixes

• Fix bug in the update() function when used with extended diagnostics. #3007 #3008
• Fix bug when inserting into arrays when using extended diagnostics. #2926 #3032 #3037

:zap: Improvements Binary formats

• Custom allocators are now supported when writing binary formats (e.g., CBOR, MessagePack) into a std::vector. #2982 #2989

User-defined type support

• Allow conversion from types that do not define an explicit iterator type, but have a begin() and end() function. #3020

Tests and CI

• Updated the Docker image used in the CI. #2981 #2986
• Corrected the compiler version mentioned in the README file. #3040

Documentation

• Add script to generate docset for Dash, Velocity, and Zeal. #2967

:fire: Deprecated functions

Passing iterator pairs or pointer/length pairs to parsing functions (basic_json::parse, basic_json::accept, basic_json::sax_parse, basic_json::from_cbor, basic_json::from_msgpack, basic_json::from_ubjson, basic_json::from_bson) via initializer lists is deprecated. Instead, pass two iterators; for instance, call basic_json::from_cbor(ptr, ptr+len) instead of basic_json::from_cbor({ptr, len}).

The following functions have been deprecated in earlier versions and will be removed in the next major version (i.e., 4.0.0):

• Function iterator_wrapper are deprecated. Please use the member function items() instead.
• Functions friend std::istream& operator<<(basic_json&, std::istream&) and friend std::ostream& operator>>(const basic_json&, std::ostream&) are deprecated. Please use friend std::istream& operator>>(std::istream&, basic_json&) and friend operator<<(std::ostream&, const basic_json&) instead.

All deprecations are annotated with HEDLEY_DEPRECATED_FOR to report which function to use instead.
