CRAN release 0.10.0

nanonext 0.10.0

New Features

• ncurl_aio() has been separated into a dedicated function for async http requests.
• Receive functions add mode = 'string' as a faster alternative to 'character' when receiving a scalar value.

Updates

Please review the following potentially breaking changes, and only update when ready:

• ncurl() argument 'async' is retired. Please use ncurl_aio() for asynchronous requests.
• ncurl() now always returns the response message body at $data whether convert is TRUE or FALSE.
• The argument 'keep.raw' for all receive functions (previously-deprecated) is removed.
• cv_reset() and cv_signal() now both return invisible zero rather than NULL.
• Function device() is removed partially due to its non-interruptible blocking behaviour.

Other changes:

• Improvements to recv (mode = 'serial') and ncurl():
  • Failure to unserialize, or convert to character, automatically saves the data as a raw vector for recovery, generating a warning instead of an error (as was the case prior to v0.9.2).
• Improvements to vector send/recv (mode = 'raw'):
  • Higher performance sending of vector data.
  • Permits sending of NULL, in which case an empty vector of the corresponding mode is received.
  • Character vectors containing empty characters in the middle are now received correctly.
  • For character vectors, respects original encoding and no longer performs automatic conversion to UTF8.
• Base64 and SHA hash functions now always use big-endian representation for serialization (where this is performed) to ensure consistency across all systems (fixes #14, a regression in nanonext 0.9.2).
• Package installation now succeeds in certain environments where 'cmake' failed to make 'libmbedtls' detectable after building (thanks @kendonB #13).
• Source bundles for 'libmbedtls' and 'libnng' slimmed down for smaller package and installed sizes.
• Configures bundled 'libmbedtls' v3.4.0 for higher performance.
• Supported 'libmbedtls' version increased to >= 2.5.
