+==== 2022-09 ====
+Release Date: 23/09/2022
+Build Number: TBC
+This release brings the following changes:
+General:
+  * All drivers now have a configurable startup timeout (defaults to 2 minutes). This prevents rogue or badly-configured drivers from blocking App Store Connect startup.
+  * Generation of tag mappings in all data stream rules has been rewritten to improve startup time.
+  * Data stream rules can now specify a minimum sample quality filter e.g. a rule can specify that source values with bad quality are discarded instead of being forwarded to destination tags.
+  * Data stream rules can now have a startup priority associated with them. Note that this cannot yet be assigned via the App Store Connect UI.
+  * Fixes an issue where script tags can get "stuck" when processing a data set containing duplicate timestamps for an individual tag.
+Big Data Event Source:
+  * Improvements to the way message backlogs/historical catch-up are processed.
+CSV Data Source:
+  * CSV driver can now optionally filter out samples that duplicate the same value on contiguous rows. This is useful when running demo data sets with large numbers of tags and rows.
+IP Historian/Edge Historian Data Source:
+  * Add metrics related to writing samples to the historian archive.
+  * Fix issue where description and unit tag search filters were not being correctly applied.
+Modbus Data Source:
+  * Startup performance improvements when using mapping CSV files that reference a large number of Modbus addresses.
+  * Reduction in memory usage when polling Modbus devices and when caching snapshot values.
+  * Add metrics related to polling of Modbus devices.
+  * Default operation delay on Modbus data sources is now 100ms. This ensures better reliability when connecting to a serial port device.
+Remapper Data Source:
+  * New preview driver (currently available in alpha channel only).
+  * Acts as a reverse proxy to tags on other data sources (i.e. allows you to create a single data source where tags from multiple other data sources can be queried).
+  * Mappings configured via CSV file.
+Serial Printer Event Source:
+  * Driver extended to expose "handshake" control protocol properties used in establishing a serial port communication.
+  * "Intelligent Response" implemented. This allows the driver to detect and respond to control messages written to the serial port.
