App Store Connect Release Notes

This page describes the release notes for App Store Connect. Your App Store Connect will automatically download the update. You can configure the update schedule for your App Store Connect by following the instructions available here.

2022-04

Release Date: 2022-04-29

Build Number: 17828

This release brings the following changes:

General:

  • Improved telemetry metrics.
  • New content security policy for the App Store Connect user interface.
  • Mitigations against some websocket deadlock issues that can prevent App Store Connect from being stopped or restarted.
  • The timeout used by App Store Connect when registering with the Industrial App Store has been increased.
  • Improvements to the way that App Store Connect processes requests received from the Industrial App Store. These improvements will be enabled automatically once the changes are enabled in the IAS Data APIs.
  • Improvements to the way that data stream rules are initialised, so that rules are now initialised in serial to reduce overhead at startup time when multiple rules with large numbers of tag mappings are used.
  • Improvements to the way that App Store Connect notifies the Industrial App Store of driver lifetime events.

Alarm Analysis Event Sink:

  • When parsing events generated by Facit, the tag and alarm identifier are now inferred from the script tag name and event name respectively.

Edge Historian:

  • Fixes an issue where the text display value for a sample could be incorrect in requests for interpolated or average values.

Modbus:

  • Improved health check UI messages.
  • Sub-second polling intervals can now be specified.
  • Tags that do not use a Modbus address as their tag name are now always sorted first in tag searches.
  • Driver can optionally prevent its default polling interval from being overridden by individual tag definitions.

Azure Event Hubs:

  • Azure Event Hub drivers now have support for message digests (SHA-384), HMAC-based message signatures (HMAC-SHA384), and encrypted message bodies (AES-256-CTR).

Taggle:

  • Fixed some tag indexing bugs.

2022-01

NOTE: Roll-out of this release was paused due to issues where some clients did not have .NET Framework 4.8 installed. Roll-out will resume on 11 March.

This release brings the following changes:

General:

  • .NET Framework 4.8 required.
  • App Store Connect will now compress query responses it sends to the Industrial App Store by default.
  • Improvements to driver initialisation.
  • Improvements to data stream when initialising auto-archiving data stream rules for data sources.
  • Script tags can now configure an evaluation delay that is applied between the trigger firing and the script being evaluated.
  • When creating a script tag, the start time for the initial calculation can be supplied instead of being inferred from the input data settings. This allows the script tag to start calculating from any point in history up until the current time.

Alarm Analysis:

  • Improvements to advanced filter queries.

OPC Classic:

  • Set default DCOM authentication level on remote OPC connections to Packet Integrity as required by Microsoft's mitigations for CVE-2021-26414.
  • Fixes an issue where some OPC AE event message fields were not included in the equivalent App Store Connect event message object.

TCP Printer Event Source:

  • Refactored to share the same core implementation as the Serial Printer Event Stream driver.
  • Limitations can now be placed on the number of concurrent TCP sessions.

Azure Event Hub:

  • New preview drivers for publishing values to and receiving values from Microsoft Azure Event Hubs. The consumer driver also has the ability to parse arbitrary JSON payloads into separate tag values.

Metrics:

  • New preview driver for collecting readings from OpenTelemetry-compatible metric instruments and publishing them as tag values.

2021-09

This release brings the following changes:

General:

  • Telemetry improvements.
  • App Store Connect now uses v2.2 of the App Store Connect adapter toolkit when connecting to 3rd party drivers (https://github.com/intelligentplant/AppStoreConnect.Adapters).
  • In limit monitor script tags, you can now choose how the monitor should handle scenarios where a limit tag value is NaN. Previously, it was only possible to configure this behaviour for process tag values, meaning that a NaN limit tag value could cause the calculation's progress to become stuck.
  • Aggregate calculator script tag template now uses the timestamp provided to it by the script engine when computing samples, rather than the timestamp returned by the underlying historian that aggregates the data.
  • Fixes an issue where computing the previous trigger time before a start time for a CRON schedule could result in the start time being returned by mistake.
  • Fixes an issue where event sources that were run out-of-process did not correctly create subscriptions to emit event messages.
  • Refactor data stream implementation (for transferring real-time or historical data from source to destination data sources) to improve handling of downstream back pressure.
  • Snapshot data stream rules that use a forwarding interval can now choose to forward only the most-recently-received values for each tag at the end of each interval.
  • Allow HTTP requests being sent to an App Store Connect (e.g. from a process control network) to use GZip compression in the request body.

Alarm Analysis:

  • Adds support for importing and exporting Alarm Response Manual with custom field support. The update changes the way that ARM data is indexed and will perform a one-off reindex of existing records; existing ARM users are advised to check their data after applying the update. Full documentation is available in the App Store Connect user interface under Documentation / Alarm Analysis / Alarm Response Manual (ARM).
  • When visualising Alarm Analysis data in Gestalt Trend, data series will now be displayed using trailing edge instead of interpolating a straight lie between samples.

AVEVA Wonderware:

  • Fixes an issue where multiple results could be returned for digital tags in tag search and data queries.
  • Fixes an issue where values-at-times queries returned NaN values.
  • Adds support for Wonderware 2010 running on SQL Server 2008 SP3.

Big Data Event Source:

  • Modification of how “lag” is handled during document polling. The “Lag” parameter protects against skipping past documents that have not appeared in the Elasticsearch index yet (documents do not appear until an index refreshes, and even then, not all documents appear simultaneously). Rather than filtering for documents that have a “creation-time < now-lag”, we now exclude documents that have a “route.timestamp > now-lag”. This provides better protection for deployments where events transit through multiple nodes/hops (i.e. where the creation time may no longer be a recent value).

CSV:

  • Performance and resource usage improvements when aggregating CSV data.

HTTP Proxy:

  • If the endpoint for an HTTP proxy data source is not available when the driver starts, an error will now be raised immediately instead of the driver getting caught in an infinite retry loop.
  • HTTP proxy data source can now optionally disable persistent real-time connection if it is not required.

IP Historian/Edge Historian:

  • IP Historian data stream rule will now automatically create a mapping if a source tag is created that is already referenced by an existing destination IP Historian tag.
  • Fixes an issue where a tag's compression filter would temporarily block incoming values if the last-archived value for the tag was NaN.

Modbus:

  • Adds support for reading/writing 64-bit numeric values (IEEE 754 floating point, signed/unsigned long integers).
  • Adds support for reading/writing UTF-8 strings (in addition to existing support for ASCII strings).
  • Allows a hosted Modbus device to be configured using the same CSV device map files used when connecting to remote Modbus devices. This allows Modbus devices hosted by App Store Connect to use all supported Modbus data types instead of coercing all values received from other data sources into 32-bit floating point numbers.
  • Attempts to write NaN values to address ranges intended for numeric values via Data Core will now be rejected.

OPC UA:

  • Non-fatal connection issues no longer cause the OPC UA driver to stop processing a subscription. Previously, an intermittent issue such as a timeout when polling the OPC UA server to check for new subscription items would cause the driver to treat the subscription as completed with a failure.
  • Self-signed X.509 client certificates can now be loaded from the Windows certificate store as well as from the file system.

2021-05

This release brings the following changes:

General:

  • General bug fixes and improvements.
  • Initial support for exporting App Store Connect trace information using the OpenTelemetry standard.
  • App Store Connect now uses v2.0 of the App Store Connect adapter toolkit when connecting to 3rd party drivers (https://github.com/intelligentplant/AppStoreConnect.Adapters).
  • New script tag templates.
  • Naming conventions can optionally be enforced when creating data sources [PREVIEW].
    • This allows rules to be defined so that e.g. all Modbus data sources on a node must have a name that starts with 'Modbus-'.

IP Historian/Edge Historian:

  • Performance and stability improvements.

AVEVA Wonderware:

  • Performance and stability improvements for the AVEVA Wonderware driver.

OPC UA:

  • Performance and stability improvements for the OPC UA driver.

MT Connect:

2021-02

App Store Connect Service update available.

The App Store Connect Service is the host that supports the running App Store Connect process. Unlike the App Store Connect process, it requires manual intervention to update. The service can be updated by downloading and running the App Store Connect Installer.

NB. Reinstalling App Store Connect may reset some custom configuration options. If in doubt, consult support@intelligentplant.com.

Changes include:

  • Improved shut-down and restart control
  • Requires .Net 4.8 (included in installer)

2021-01

This release contains the following changes:

  • Recovery improvements when an App Store Connect is unexpectedly disconnected from the Industrial App Store (e.g. due to a network issue).
  • Improvements to Edge Historian query performance.
  • Improvements to the Alarm Analysis programmable transform.
  • The Modbus driver can now be used to host a virtual Modbus TCP device.

2020-10

  • Alarm Analysis licensing. Unlicensed AA (Alarm Analysis) data sources will respond with 'Subscription not found or expired' message which indicates that the data source needs to be licensed. For details on how to apply a licence please check the steps here or contact support@intelligentplant.com.

2020-07

  • Alarm Analysis Data Source Driver
    • Day count aggregations simplified to use a 24hr period. Previously, the Alarm Analysis driver would accomodate time-zone logic. Now however, it is the responsibility of the calling app (e.g. Alarm Analysis, SoE Explorer, Facit, etc…) to handle timezone.
    • Foundations for Alarm Analysis licensing.

2020-05

This release contains the following changes:

  • Improvements to the Alarm Analysis data source driver in preparation for the next Alarm Analysis app release.
  • Edge Historian tags can be configured to record the current value only (i.e. no history).
  • New aggregate functions supported in Edge Historian: `AnnotationCount`, `Count`, `PercentGood`, `PercentBad`, `Range`, `Delta`, `StdDev`, `Variance`
  • `Range` aggregate function now supported in OSIsoft PI and AF drivers.
  • Improvements to automatic reconnection in PI and AF drivers.
  • Fix for older versions of IE when browsing tags in the App Store Connect UI.
  • Improvements to the App Store Connect trending UI.
  • Miscellaneous small improvements.

2020-03

This release contains the following changes:

  • Improvements and bug fixes related to Alarm Analysis data import and reporting queries.
  • Improvements and bug fixes related to the restart of data stream rules (used to transfer real-time data from a source data source to a destination data source such as App Store Connect's Edge Historian).
  • Fixes for some C# script tag templates that called back into Data Core for historical data.
  • JavaScript-based script tags are now deprecated in favour of C#-based script tags.
  • A new driver for Aspentech IP.21, capable of interfacing with its HTTP-based REST API. This driver is in preview and will receive improvements over the coming months.
  • Miscellaneous bug fixes.
