CRAN release 0.13.0

nanonext 0.13.0

Updates

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

• Default behaviour of send() and recv() aligned to non-blocking for both Sockets and Contexts (facilitated by synchronous context sends in NNG since v1.6.0).
• ncurl(), ncurl_aio() and ncurl_session() now restrict 'header' and 'response' arguments to character vectors only, no longer accepting lists (for safety and performance).
• Unserialization / decoding errors where the received message cannot be translated to the specified mode will output a message to stderr, but no longer generate a warning.
• SHA functions now skip serialization headers for serialized R objects (ensuring portability as these contain R version and encoding information). This means that, for serialized objects, hashes will be different to those obtained using prior package versions.
• sha1() is removed as a hash option.

Other changes:

• messenger() specifying 'auth' now works reliably on endpoints using different R versions/platforms due to the above hashing portability fix.
• Internal memory-efficiency and performance enhancements.
• Upgrades bundled 'libmbedtls' to v3.5.2.
