- Lots of changes for migrating C code to C++ - Improved `Lockable` in several ways like adding `withLock()` (+ tests) - Improved `Semaphore` a bit for improved readability, and also added some tests - Upgrade Linux machine in GitHub Actions so that we can compile with a newer GCC - Simplification of WiFi connection - Updated funding options - (and more)
