CRAN release 0.8.3

nanonext 0.8.3

New Features

• Implements cv_signal() and timed_signal() for signalling a condition variable, the latter after a specified time (from a newly-created thread).
• Implements .context(), a performance alternative to context() that does not create the full object.
• Adds utility nanonext_version() for providing the package version, NNG and mbed TLS library versions in a single string.
• ncurl() gains a 'timeout' argument.

Updates

• Removes 'verify' argument of context() (changed to '...' for compatibility) as request() and request_signal() have been rendered safe internally for use with timeouts.
• The name of the single argument to msleep() has been changed to 'time' from 'msec'.
• Functions pipe_notify(), lock() and unlock() now error if unsuccessful rather than returning with a warning.
• For compiling bundled 'libmbedtls' and 'libnng' libraries from source, R's configured C compiler is now chosen over the system default where this is different.
• Bundled 'libnng' source updated to v1.6.0 alpha (c5e9d8a).
• Bundled 'libmbedtls' source updated to v3.4.0.
