July 1, 2026
v2.2.12 stable release
Updates:
- Fix remaining
multiple definition of 'firebase_ns::JWT'linker error on pre-C++17 toolchains (e.g. Arduino-ESP32 core 2.x compiled as gnu++11) when includingFirebaseClient.hin more than one source (.cpp) file (#329). The v2.2.11 fix relied on C++17inlinevariables, which are ignored below C++17. The now-unused globalJWTobject has been removed and the globalOTAUpdaterobject is now a function-local (Meyers) singleton, so a single shared instance is guaranteed across translation units on every C++ standard.
