**Major:**
1. Backoff in case of d2c messaging throttling, stopping telemetry and twin operations
2. Improve perf reducing load on garbage collector and disposing IoT SDK resources
3. Improve device twin management, e.g. try to avoid twin writes when data is not changed, handle more error scenarios
4. Add "development" feature flag to enable/disable expensive runtime checks
5. Change partitions size from 1000 to 5000 devices to reduce the load on storage
**Minor:**
1. Backoff in case of device count throttling (e.g. when reaching 8000 devices in the free SKU)
2. Remove unused daily counter for telemetry
3. Improve perf reducing the number of no-op async tasks
4. Update IoT SDK and other dependencies
5. Clean up logging code, reimplement log filtering (removed in past PRs)
6. Print SDK version at startup
7. Add some scripts for development, see /scripts/development (create/delete simulation, start storage adapter)
**Bug fixes:**
1. Handle and recover from exceptions in the partitioning agent
2. Fix some swallowed errors/exceptions and unnecessary try/catch
3. Share script interpreter between methods and state to ensure device state consistency
4. Fix logged throughput in case of no traffic, i.e. show 0.0 msg/sec, and round value to 3 decimals
5. Fix logging from ConfigData
6. Change the dev endpoint used to delete simulations: don't delete devices (the endpoint was not working) - no user impact, dev only

* Updating state script files to use a consistent pattern for updating state, and corresponding documentation and interperter changes.
* PR feedback.
* Restoring TempIncrease, TempDecrease, FillTank, and EmptyTank methods, as RemoteMonitoring doesn't support method arguments now. Also: implemented these methods and made some corresponding tweaks to state files that can be impacted by the state that these methods change.
* Added state-restoration to temperature methods so that they won't error out if a previous state hadn't been set by the time they were called, and did some whitespace clean up and other minor clean up.

Use external Javascript functions to generate the telemetry for simulated devices. The path of folder that contain the Javascript files can be configured, so it's possible to mount JS files from anywhere. Files are loaded at runtime. The name of the files is specified in the Device Type JSON files, which are managed in the same way, with a configurable path and loaded at runtime.
Javascript files are interpreted using Jint https://github.com/sebastienros/jint .
Documentation here: https://github.com/Azure/device-simulation-dotnet/wiki/Device-Types
This adds a new endpoint to list all the supported device types. Device types are configured via JSON files external to the assembly, so that users can add custom types without rebuilding the service. The files include a README describing the format of these files.
I was going to use HOCON for these files too, for a cleaner look, but I'm actually reconsidering that approach and the use of Newtonsoft greatly reduces the code required to parse these files (at least in .NET).
