+# Change Log
+
+## 1.1.0 (2017-03-10)
+
+- Provisions enable implementing dynamic device configuration or complex device
+provisioning work flow using arbitrary scripts.
+- Virtual parameters are user-defined parameters whose values are evaluated from
+a custom script.
+- Extensions are sandboxed Node.js scripts that are accessible from provision
+and virtual parameter scripts to facilitate integration with external entities.
+- Support for UDP/STUN based connection requests for reaching devices behind
+NAT (TR-069 Annex G).
+- Presets can now be scheduled using a cron-like expression.
+- Presets can now be tied to specific device events (e.g. boot).
+- Presets precondition queries no longer support "$or" or other MongoDB logical
+operators.
+- Faults are no longer a part of tasks but are now first class objects.
+- Presets are now assigned to channels. A fault in one channel only blocks
+presets in that channel.
+- New API CRUD functions for provisions, virtual parameters, and faults.
+- New config options for XML output.
+- API responses now include "GenieACS-Version" header.
+- Graceful shutdown when receiving SIGINT and SIGTERM events.
+- Support SSL intermediate certificate chains.
+- Supported Node.js versions are 6.x and 7.x.
+- Supported MongoDB versions are 2.6 through 3.4.
+- Expect performance differences due to major under the hood changes. Some
+operations are faster and some are slower. Overall performance is improved.
+- GenieACS will no longer fetch the entire device data model upon first contact
+but will instead only fetch the parameters it needs to fulfill the presets.
+- Logs have been overhauled and split into two streams: process log (stderr) and
+access log (stdout). Also added config options to dump logs to files rather than
+standard streams.
+- Connection request authentication credentials are picked up from the device
+data model if available. config/auth.js is still supported as a fallback and now
+supports an optional callback argument.
+- Custom commands have been removed. Use virtual parameters and/or extensions.
+- Aliases and value normalizers (config/parameters.json) have been removed. Use
+virtual parameters.
+- The API /devices/<device_id>/preset has been removed.
+- Rarely used RequestDownload method no longer supported.
+- The TR-069 client simulator has moved to its own repo at
+https://github.com/zaidka/genieacs-sim
