<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
Known issue: If the "Drop Unused Model After" setting is specified for a model, the model may incorrectly be dropped from the memory when the memory consumption is high. As a workaround, set this setting to empty, so that the model is not dropped by itself. This incorrectly behaving setting will be removed from the software in the next release.
Known issue: It's not possible to move projects that existed before updating to this release. The issue will be fixed in the next release. There is a following workaround available: Administrator user can go to the [[Navigation_Menu#Expression_Designer|Expression Designer]] and run the following expression: '''Projects.Modify(#{})'''.

== Additional release for QPR ProcessAnalyzer 2021.9 (build 709) (released 2021-12-20) ==
== Additional release for QPR ProcessAnalyzer 2024.5 (build 6769) (released 2024-06-27)==
 
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
This release has brought back SQL Server 2014 support.
</div>


'''Features:'''
'''Features:'''

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
'''Fixed issues:'''
Starting from QPR ProcessAnalyzer 2021.9, ScriptLauncher uses Web API instead of legacy WCF API, and thus also the ScriptLauncher needs to be updated to 2021.9. In addition, in the ScriptLauncher configuration file, ''ConnectionType'' setting needs to be ''WebApi'' (the setting is in place in the 2021.9 release package). The new Web API based ScriptLauncher is not anymore dependent on the API protocol version, and thus starting from 2021.9, information about the protocol version is not published. The old ScriptLauncher using protocol version 39 still works with the 2021.9, but as the WCF API is deprecated, ScriptLauncher update is mandatory before updating to 2022.1.
</div>


<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
*D-14187: Creating local datatables was not possible in Workspace if datatables were stored to the configuration database (i.e., SqlServerConnectionString setting is not used).
When taking into use the Web API based ScriptLauncher, the ServiceUrl setting in the ScriptLauncher [[QPR_ProcessAnalyzer_ScriptLauncher#Configuring_ScriptLauncher|configuration file]] needs to be set differently: Previously it was enough to specify the server name (e.g. <nowiki>https://processanalyzer.onqpr.com</nowiki>), but now also the application path needs to be specified (e.g. <nowiki>https://processanalyzer.onqpr.com/qprpa</nowiki>). This issue will be resolved in upcoming release.
</div>


<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
==QPR ProcessAnalyzer 2024.5 (build 6746) (released 2024-06-25)==
Starting from QPR ProcessAnalyzer 2021.9, support for SQL Server 2012 and SQL Server 2014 has been dropped. See more in [[QPR_ProcessAnalyzer_System_Requirements#System_Requirements_for_QPR_ProcessAnalyzer_Server|system requirements]].
</div>
 
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
The predefined analyses operations that QPR ProcessAnalyzer has traditionally been based on, are now deprecated and will be replaced by functionality provided by the expression language. In practice, the following features will be removed:
* [[SQL_Scripting_Commands#--.23GetAnalysis|--#GetAnalysis]] command in SQL scripting: If there are scripts using that command, replace them with the new [[SQL_Scripting_Commands#--.23RunQuery|--#RunQuery]] which uses the expression language to query data.
* [[DataFrame_in_Expression_Language#Extract_Data_to_DataFrames|Analysis]] function in expression language: If using that function, replace it with other functionalities provided by the expression language.
* POST /api/analysis/{analysisType} endpoint in the Web API: If using that endpoint in customized solutions, call the [[Web_API:_Expression/query|/api/expression/query]] endpoint instead.
</div>
 
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
QPR ProcessAnalyzer WCF API is now deprecated and it will not be available starting from 2022.2 release. All customized integrations and other solutions that use WCF API need to be converted to use [[QPR_ProcessAnalyzer_API|Web API]]. Note that there may also exist scripts that contact the WCF API using the [[SQL_Scripting_Commands#--.23CallWebService|--#CallWebService]] command. The used API can be distinguished from the url: if it contains "/MainService.svc" the connection is to the WCF API and changes are required.
</div>
 
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
When installing 2021.9 server, note that there is a change in the web.config file, as httpRuntime element includes now targetFramework="4.7.1" attribute. Also, QPR ProcessAnanalyzer ScriptLauncher web.config has changed, as ''ConnectionType'' is now ''WebApi'' instead of ''Service''.
</div>
 
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
SQL scripting commands that create datatables and temporary tables, use now specific column data types (such as NVARCHAR(MAX), INT, FLOAT, DATETIME2 and BIT) instead of SQL_VARIANT. This may affect SQL commands that have relied on the SQL_VARIANT column type. For example, in joins there may be mismatches between data types, requiring explicit type conversion.
</div>

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
Known issue in 2021.8: Some dashboards created with earlier releases, may give following error when opened: ''Chart settings are invalid, and the chart may not work correctly. Type of property "measures/0/nullValue" must be string."'' Despite the error message, the dashboard still works correctly. The issue can be resolved by going through all charts in the dashboard and opening the ''Chart settings'' (in the ''Advanced'' tab). If the settings contain one of the following: ''nullValue: null'', ''emptyStringValue: null'', ''trueValue: null'' or ''falseValue: null'', replace them follows: ''nullValue: ""'', ''emptyStringValue: ""'', ''trueValue: ""'', ''falseValue: ""''. When changes have been made, save the dashboard and check that there is no error, when the dashboard is opened. This issue will also be fixed in the next release, and if decided to wait for it, there is no need to edit the dashboards.

Known issue in 2021.8: Some dashboards created with earlier releases, may give following error when opened: ''Chart settings are invalid, and the chart may not work correctly. Property "expressionType" is required in dimensions/0."'' In addition to the error message, some charts in the dashboard may not work correctly. This issue appears if there are empty measures or dimensions ("none" selected) above defined measures or dimensions. The issue can be resolved by removing the empty measures and dimensions by clicking the ''Remove'' button for the measure/dimension. This may affect how the remaining measures and dimensions are mapped to the visualization, so the mappings may need to be adjusted in the measure/dimension settings. When changes have been made, save the dashboard and check that there is no error, when the dashboard is opened. This issue will also be fixed in the next release, and if decided to wait for it, there is no need to edit the dashboards.

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
There is a breaking change in 2021.4 related to using tags in custom expressions: If a tag provides a string value, before it was written e.g. ''Attribute("<#AutomationAttribute>")'', but now it needs to be written ''Attribute(<#AutomationAttribute>)'', because the quotation marks of the string literal now come with the value replacement. The former will cause error in 2021.4, as there will be two sets of quotation marks. This problem does not concern other type of values (e.g. numeric), as they don't have quotation marks.
QPR ProcessAnalyzer Server and QPR ScriptLauncher are now using .Net 8 (previous was .Net 6). When updating to this release, install the .Net 8 Runtime ([[Updating_QPR_ProcessAnalyzer_Server|see more]]). The .Net 6 doesn't need to be uninstalled immediately because .Net 6 and .Net 8 work side-by-side, but due to security reasons, the unused .Net 6 should eventually be uninstalled.

Scripts that are stored to the ''model'' or ''user'' context are not available in the scripting web UI (scripts in ''project'' and ''system'' context are available). If you have scripts in the model or user context, they need to be recreated in the project or system context using the Excel Client latest in 2021.4. Starting from 2021.5, scripts in the model or user context are preserved in the system, but cannot be used anymore (and they will be removed in a future release).
In this release, all filters that don't contain any filter rules, are removed. These are legacy filters which have not been visible in the UI.

'''Features:'''
*B-08019: New component [[Design Diagram]] for showing user-created diagrams in dashboards where to visualize process mining metrics.

*B-08175: Workspace should show timestamps in user's local time.
'''Fixed issues:'''
* D-13913: Datatable properties dialog incorrectly showed linked models from other projects.

Tables used in dashboards are updated to the next generation of Syncfusion JS2 components. The [[QPR_ProcessAnalyzer_Chart#Visualization_Settings|Custom layout]] settings (defined as JSON) of the table might not be compatible between the generations, and thus they need to be changed manually after updating to 2021.4. See instructions how to migrate settings between the generations of the component: https://ej2.syncfusion.com/documentation/grid/ej1-api-migration/.
Limitation for the maximum amount of data (B-07636) causes a behavior change in in-memory charts that have the Maximum rows settings empty and have the sorting defined. In certain cases, the order in which measures are evaluated changes (due to an internal performance optimization). If there are custom expressions that define variables, the variables may not be available in other measures anymore. As a resolution, either redefine the variables in those measure expressions or add those measures secondarily to the sorting.

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
Starting from QPR ProcessAnalyzer 2021.4, the Data Grid Export Service (used for exporting tables as Excel files) is not needed anymore. The renewed table is able to create export files in the browser side without using any server/cloud side service. If the Data Grid Export Service has previously been installed, it's recommended to uninstall it for security reasons (to reduce attack surface).
Default query timeout of 30 minutes has been added for --#ImportOdbcQuery, --#ImportSqlQuery and --#ImportOleDbQuery commands. If a query run is taking longer than the timeout, the query is stopped. The timeout can be adjusted using the '''QueryExecutionTimeout''' parameter. Previously, there has been no timeout, so queries that take more than 30 minutes require configuring a longer timeout.

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
There is a new step in the QPR ProcessAnalyzer server installation instructions for allowing large process mining models: [[Installing_QPR_ProcessAnalyzer_Server#.Net_Configuration:_gcAllowVeryLargeObjects|.Net configuration: gcAllowVeryLargeObjects]]. The change should also be done for earlier QPR ProcessAnalyzer server versions if using models that have more than 50 million events.
Incorrectly configured [[Chart_Linked_Settings|linked settings]] in charts (available in the ''Advanced'' tab) give now an error message, if they are referring to non-existing measures, dimensions or columns. Previously, incorrect linked settings were ignored. To fix the error message, remove the incorrect linked settings.

There is a potential performance issue with the list of models in the header, which may appear when there are dozens of models in the list. When there are lot of models, the models list jams the UI when opened. The next release (build 163) has solved the issue.
In Big Data Chart, the '''Case conformance''' measure and dimension has changed in a way that now it provides boolean values (true/false) instead of integer values (1/0). If [[Measure,_Dimension_and_Column_Settings#Other_settings|colorMappings]] are used for this measure or dimension to set specific colors to visualize conformant and nonconformant cases, the mapped values need to be changed as follows: '''1''' -> '''true''' and '''0''' -> '''false'''. Without the change, the mapped colors are not effective.
 
Exmaple: Old configuration:
<pre>
"colorMappings": {
  "1": "#36d475ff",
  "0": "#f5403bff"
}
</pre>
New configuration:
<pre>
"colorMappings": {
  "true": "#36d475ff",
  "false": "#f5403bff"
}
</pre>
</div>
</div>


<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
QPR ProcessAnalyzer 2021.1 does not have the '''Data Grid''' and '''HTML''' presentation objects, and they have been replaced by easier-to-use and more powerful [[QPR_ProcessAnalyzer_Chart|Chart]] presentation object, which supports many layouts such as [[QPR_ProcessAnalyzer_Table|tables]]. After updating to QPR ProcessAnalyzer 2021.1, existing dashboards containing Data Grid and HTML presentation objects will contain a placeholder with a message that the presentation object doesn't exist. That placeholder can be removed and replaced with the Chart presentation object. If you need to preserve settings for the removed presentation objects, that needs to be done before updating to QPR ProcessAnalyzer 2021.1.
Big data chart support of models with local datatables (i.e., SQL Server stored) is deprecated. Big data chart has allowed to process data both in Snowflake and SQL Server. Now the support for SQL Server is deprecated and the Big data chart will only support calculation in Snowflake. If there are big data charts using SQL Server calculation, either migrate data to Snowflake or switch to in-memory charts (requiring to load data in-memory).

Data types of the datatables and temporary tables created by the [[SQL Scripting Commands#--.23ImportSapQuery|--#ImportSapQuery]] command has been changed: previously data types were NVARCHAR(255) for all columns. Now the maximum length in the NVARCHAR data type depends on the SAP data field length. This optimizes the space needed for data storage. In addition, there is a new parameter '''ConvertDataTypes''' allowing to specify which data types are converted correctly instead of using textual format.
Following legacy analyses have been removed: Operation log (analysis number: 12), Root causes (14), Correlations (15), Idea feed (16) and Duration influence (29). This functionality may be in use in SQL scripts (in [[SQL_Scripting_Commands#--.23GetAnalysis|--#GetAnalysis]] command), and thus needs to be changed to the [[SQL_Scripting_Commands#--.23RunQuery|--#RunQuery]] command (see the [[RunQuery_Script_Examples|examples page]] how each legacy analysis can be replaced). The OperationLog analysis is replaced by the [[Generic_Properties_in_Expression_Language#OperationLog|OperationLog function]] and the Infcluencers analysis is replaced by the [[FindRootCauses_Function|FindRootCauses function]].
 
Following script can be run in the [[Navigation_Menu#Expression_Designer|Expression Designer]] to show whether there are scripts that use the removed analyses (and thus require migration):
<pre>
let removedAnalyses = [12, 14, 15, 16, 29];
OrderByDescending(Flatten(Projects.Scripts).Where({
  let scr = _;Sum(removedAnalyses.("'AnalysisType','" + _ + "')").{let num=_;(scr.code ?? "").Replace(" ", "").Replace("\t", "").Replace("\n", "").Replace("\r\n", "").Replace("\r", "").Contains(num)})>0;
}),LastRunStart).(Project.Name + ": " + name + " (id: " + id + ") (last run: " + (LastRunStart ?? "N/A") + ")");
</pre>
</div>
</div>
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
By default, Snowflake ODBC driver generates quite much logging to files which might unnecessarily fill up the disk space. It's recommended to set the LogLevel parameter to value 0. The path where the logs are created can be seen in Windows registry (key LogPath). More information about configuring Snowflake ODBC parameters: https://docs.snowflake.com/en/developer-guide/odbc/odbc-parameters.

QPR ProcessAnalyzer 2023.7 (build 4326) (released 2023-11-28)

Limitation for the maximum amount of data (B-07636) causes a behavior change in in-memory charts that have the Maximum rows settings empty and have the sorting defined. In certain cases, the order in which measures are evaluated changes (due to an internal performance optimization). If there are custom expressions that define variables, the variables may not be available in other measures anymore. As a resolution, either redefine the variables in those measure expressions or add those measures secondarily to the sorting.

Default query timeout of 30 minutes has been added for --#ImportOdbcQuery, --#ImportSqlQuery and --#ImportOleDbQuery commands. If a query run is taking longer than the timeout, the query is stopped. The timeout can be adjusted using the QueryExecutionTimeout parameter. Previously, there has been no timeout, so queries that take more than 30 minutes require configuring a longer timeout.

Incorrectly configured linked settings in charts (available in the Advanced tab) give now an error message, if they are referring to non-existing measures, dimensions or columns. Previously, incorrect linked settings were ignored. To fix the error message, remove the incorrect linked settings.

Features:

  • B-07511: Datatables have a dialog to view datatable properties, write description, set the Snowflake source table, add/modify/delete columns, and set the datatable key.

QPR ProcessAnalyzer 2023.5 (build 3304) (released 2023-09-05)

In Big Data Chart, the Case conformance measure and dimension has changed in a way that now it provides boolean values (true/false) instead of integer values (1/0). If colorMappings are used for this measure or dimension to set specific colors to visualize conformant and nonconformant cases, the mapped values need to be changed as follows: 1 -> true and 0 -> false. Without the change, the mapped colors are not effective.

Exmaple: Old configuration: 

"colorMappings": {
  "1": "#36d475ff",
  "0": "#f5403bff"
}

New configuration: 

"colorMappings": {
  "true": "#36d475ff",
  "false": "#f5403bff"
}

Big data chart support of models with local datatables (i.e., SQL Server stored) is deprecated. Big data chart has allowed to process data both in Snowflake and SQL Server. Now the support for SQL Server is deprecated and the Big data chart will only support calculation in Snowflake. If there are big data charts using SQL Server calculation, either migrate data to Snowflake or switch to in-memory charts (requiring to load data in-memory).

Following legacy analyses have been removed: Operation log (analysis number: 12), Root causes (14), Correlations (15), Idea feed (16) and Duration influence (29). This functionality may be in use in SQL scripts (in --#GetAnalysis command), and thus needs to be changed to the --#RunQuery command (see the examples page how each legacy analysis can be replaced). The OperationLog analysis is replaced by the OperationLog function and the Infcluencers analysis is replaced by the FindRootCauses function.

Following script can be run in the Expression Designer to show whether there are scripts that use the removed analyses (and thus require migration): 

let removedAnalyses = [12, 14, 15, 16, 29];
OrderByDescending(Flatten(Projects.Scripts).Where({
  let scr = _;Sum(removedAnalyses.("'AnalysisType','" + _ + "')").{let num=_;(scr.code ?? "").Replace(" ", "").Replace("\t", "").Replace("\n", "").Replace("\r\n", "").Replace("\r", "").Contains(num)})>0;
}),LastRunStart).(Project.Name + ": " + name + " (id: " + id + ") (last run: " + (LastRunStart ?? "N/A") + ")");

By default, Snowflake ODBC driver generates quite much logging to files which might unnecessarily fill up the disk space. It's recommended to set the LogLevel parameter to value 0. The path where the logs are created can be seen in Windows registry (key LogPath). More information about configuring Snowflake ODBC parameters: https://docs.snowflake.com/en/developer-guide/odbc/odbc-parameters.
