Following **API breaking changes** were introduced:

* added a termination detector to `sync_sections`

Following non-breaking changes were introduced:

* added caching for plain metadata
* added `Sensor.write`
* failing writes will be treated the same way as failing reads - they will be logged
* added automatic order retry
* smarter waiting (time spent executing read/write/message orders counts into that too)
* added a proofing against appending a pathpoint value with lower timestamp than current
* syncing invalid data (HTTP 4xx instead of 5xx) will mark it as synchronized correctly
* made `Pathpoint.set_new_value`'s usage more ubiquitous
* since Executor will now use it to write new Pathpoint's values
* added an option to register a callable to be fired each time Pathpoint value changes
* added an option to limit the frequency of Pathpoint's reads
* added an option to read without spawning a Thread and a Future
* added an option to retrieve SMOK's master certificate
* added `NullEventDatabase`

* adjusted macro update interval
* removed extra logging from `smok.threads.executor`

~~~~

* add support for reparse pathpoints
* add support for getting archive data from sensors
