- SensorMetadata objects do not rely on shared pointers anymore, results
in a 50% (or more) reduced memory usage
- Sensor cache files are written as CSV files, bypassing BOOST's PTREE
parsing
- With a local DB instance, retrieving 100k sensors from the cache is
now between 2X and 3X faster than querying Cassandra

- Keeps track of sensor metadata in a JSON file within .cache
- Implemented at the libdcdb level
- Makes use of a lock file to prevent concurrency issues
- Can be enabled via the USE_SENSOR_CACHE compile flag

- Uses a simple string key->value schema
- Stores the timestamp of the latest edit to the publishedsensors table
- Implemented logic to update this timestamp accordingly

- A plugin to control warm-water cooling systems via SNMP
- Meant for use in the DEEP-EST project

- Fixed a memory leak when inspecting error messages
- Relaxed class methods to enable inheritance

- Fixing a crash when the REST API is disabled
- Casting and macro handling

- Fuzzy queries now work properly even when using relative timestamps
such as "now-5m"

- Specifying a target sensor is not required anymore when loading an
external model (e.g., Python OpenCV front-end)
- The structure of feature vectors now faithfully reflects the
specified configuration, its order, and is easily reproducible
