 * The abillity to `lock()` and `unlock()` sockets is removed.
 * Renders it safe to serialize 'nano' and 'aio' objects - they will be inactive when unserialized.
 * Unified Windows build system now compiles 'libmbedtls' and 'libnng' from source even on R <= 4.1 using Rtools40 or earlier.
+* Requires 'libnng' >= 1.10.0.

 **It is recommended for optimal performance and stability to let the package automatically compile bundled versions of 'libmbedtls' and 'libnng' during installation.** To ensure the libraries are compiled from source even if system installations are present, set the `NANONEXT_LIBS` environment variable prior to installation e.g. by `Sys.setenv(NANONEXT_LIBS = 1)`.
