Behavioural Changes

• mirai() argument .timeout is upgraded to automatically cancel ongoing mirai upon timeout when using dispatcher (thanks @be-marc, @sebffischer #251).
• serial_config() now accepts vector arguments to register multiple custom serialization configurations. Argument vec is dropped as internal optimizations mean this option no longer needs to be set.

New Features

• host_url() is upgraded to return all local IP addresses (named by network interface), which provides a more comprehensive solution than just using a hostname.
• Adds register_serial() to register serialization configurations for all daemons() calls (may be used by package authors as a convenience).
• Adds on_daemon() which returns a logical value, whether or not evaluation is taking place within a mirai call on a daemon.
• Adds daemons_set() which returns a logical value, whether or not daemons are set for a given compute profile.
• daemons() now supports initial synchronization exceeding 10s (between host/dispatcher/daemons). This is particularly relevant for HPC setups (thanks @sebffischer, #275).

Updates

• For all functions that use .compute, this argument has a new default of NULL, which continues to use the default profile (and hence should not result in any change in behaviour).
• Fixes stop_mirai() failing to interrupt in certain cases on non-Windows platforms, and more robust interruption if tools::SIGINT is supplied or passed through to the autoexit argument of daemon() (thanks @LennardLux, #240).
• daemons() dispatcher argument 'process', deprecated in mirai v2.1.0, is removed.
• Requires nanonext >= 1.6.0.
• Package is re-licensed under the MIT license.
