Overview

This release adds fixes and improvements, and more examples.

Built-in TLS is now able to support RSA signatures
Fixed ChaCha to work in big-endian platforms
Fixed mg_aton() not setting is_ip6 with scope_ids
Fixed checksum generation in big-endian platforms
mg_connect() now fast fails if network is down, when using Mongoose built-in TCP/IP stack
Improved TCP server local information: c->loc now holds the local address to where the remote client has connected, instead of the address given when opening the listener (usually 0.0.0.0)
Added support for DNS-SD using mDNS
Added support for Windriver's Diab v4
Added support for the RTL8211 PHY
Added support for GbE PHYs
Added support for MbedTLS 4
Added support for Wiznet's W55RP20
Added support for the ST67W6 Wi-Fi module
Added support for working with DCACHE enabled in STM32H7 and STM32N6 boards

Mongoose built-in TCP/IP stack now performs checksum validation
Improved handling of PEM certificate files, comments and chained certificates are now supported
Fixed a long standing certificate verification failure that caused apparently random verify failures

Introduced a new mDNS API, and added an mDNS client example

Added support for no options in DHCP messages
Allowed more than one address in received DHCP options. The client still uses the first one, but more than one can be sent by the server

Mongoose built-in TCP/IP stack now coexists with protocols using TCP reserved space in 'flags'
Improved Zephyr support and integration

Improved handling of HTTP fast closures
Improved built-in TCP/IP and TLS compatibility with C89 compilers
Added OTA firmware update over MQTT example
Added HTTP redirect and singleton client examples
Improved handling of malformed MQTT5 properties
Added more Wi-Fi security definitions
Improved built-in TCP/IP testing
Improved built-in TLS testing
Improved test coverage
