The is a minor release that incorporates fixes/improvements made over the last 10 months. Dependencies have been updated, and Go version 1.24 is now required (matching the "Go release policy").
I don't believe there are any breaking changes. Keepalive behaviour has been changed so that a PING is sent unless a packet has been sent AND received within the keepalive period (to address potential issues where a client is sending constantly, but never receives anything).
Note that one of the fixes addresses a potential security issue where data from one field (e.g. topic, properties) may leak into another (e.g. message body). This issue was raised against paho.mqtt.golang (issue 730) but the same code existed in this library. Thanks to Paul Gerste (Sonar) for reporting the original issue.
Thanks to those who have provided fixes/enhancements included in this release!.
