15/03/2019 (7.0.190315). Release 7.0 on GitHub

  • Replacement of Signavio with as the default editor of Apromore. is a lightweight process model editor offering a wide range of plugins supported by a large community of developers and researchers. In addition, most plugins that were previously built on top of the Signavio environment such as Log animation and model-model as well as model-log Compare plugins are also migrated to the environment.

Version 6.0

11/09/2018 (6.0.180911)

  • Various bug fixings, incl. issues with arcs creation and undo/redo in Editor.

31/08/2018 (6.0.180831)

  • New predictive monitoring plugins to train and predictively monitor event streams (using Apache Kafka). You can train a variety of predictive models for regression (predicting the value of a continuous variable) or classification (predicting the value of a discrete variable), such as decision trees, random forests, gradient tree boosting, using a variety of features encodings and bucketing mechanisms. You can compare the trained models in terms of their relative merits along earliness and accuracy dimensions, and then deploy the selected ones to a run-time environment for real-time predictive monitoring from event streams (currently, a stream can be obtained by replaying a log stored in Apromore). Predictions can then be visualized in a dashboard and exported to CSV

  • Updates to drift detection/characterization plugin: the event-based configuration now handles noise in event streams, allows one focus on the most significant process changes by decreasing the drift detection sensitivity (this functionality is particularly useful when detecting drifts on real-life event logs whose originating processes incur frequent changes), and when using a log already existing in the repository of Apromore, one can now save the sub-logs between detected drift next to your original log in the repository
  • Some plugins renamed to better reflect their functions

  • New discovery plugin “Filter out infrequent activities” allows users to remove infrequent activities, as opposed to individual events, which is done by the “Filter out infrequent behavior” plugin.
  • New analysis plugin “Check model guidelines with BEBoP” (available both from the Portal and from the Editor) allows users to check that a BPMN model.
  • New analysis plugin “Verify correctness with BProVe” (available from the Editor) allows users to verify the syntactic correctness of a BPMN model (incl. multi-pool collaboration diagrams)
  • New cloud nodes hosted by University of Melbourne (Australia) and University of Camerino (Italy).
  • Various bug fixes.


  • New plugin: Mine Process Performance builds cumulative flow diagrams, time series and detailed stage-based performance statistics from an event log.
  • New plugin: Staged Miner discovers a stage-based model from an event log, by automatically detecting milestones to separate the log into sub-logs, one per stage.
  • New plugin: Visualize Log shows the direct-follows graph of an even log, where activity and edge filters can be applied.
  • New version of Measure plugin now shows structural complexity metrics when a model is selected, as well as log statistics when a log is selected.
  • New version of ProDrift plugin now characterizes a drift discovered in terms of behavioral relations, and prompts these to the use as English statements.
  • New version of Compare plugin visualizes model2log differences as changes overlaid on the BPMN model.
  • New version of BPMN Miner plugin now supports infrequent behavior filtering of the event log.
  • BIMP process simulation plugin now accessible directly from Analyze menu (as well as from the Apromore Editor).
  • OSGi Portal plugins can now have icons to show in the menus.
  • We moved to ZK 8.0.2 and Apache Tomcat 7.0.61 on Eclipse Virgo 3.6.4 (previous versions won’t work).
  • New Apromore branding (“Advanced Process Analytics Platform”) and logo.
  • Two distributions: “one-click” is a single file to unzip somewhere and run Apromore from localhost, and “full-fledged” is the fully customizable version.
  • Various bug fixes.

Version 4.0


  • Native support for logs. Logs are now first-class citizens as process models. They can be imported and exported in XES and MXML, and be used as input to plugins, e.g. discovering a BPMN from a log.
  • Apromore fully supports PQL (process query language) to query the repository based on process behavior. This includes a major reduction of the size of the PQL applet.
  • New plugin Compare allows the following comperisons based on process behavior: model2model, model2log (conformance checking), log2log (variants mining).
  • ProDrift 2.0 released: gradual drift and event-stream based drift detection now supported.
  • BPMN Miner 2.0 released: a-posteriori structuring is now integrated into BPMN Miner.
  • OSGi architecture has been restructured to support 3 types of OSGi plugins: portal, logic and editor. A large number of existing components have now become OSGi plugins.
  • Menu items have been rearranged according to the phases of the BPM lifecycle (discovery, analysis, redesign, implementation, monitoring).
  • We moved to MySQL 5.7 (previous versions won’t work).
  • Various bug fixes.

Version 3.4


  • From the editor, one can now measure a variety of process model complexity metrics (size, CFC, structuredness…).
  • GED matrix can now be computed on a selection of folders and is multi-threading.
  • iBPStruct has been released: structuring process models with BPStruct now works again and the quality and extent of structuring has been improved.
  • Installation of Apromore has been substantially simplified (reduced footprint – Apromore can now run from a USB stick).
  • Various bug fixes.

Version 3.3


  • Apromore is now capable of identifying concept drift in logs using the ProDrift plugin.
  • New models can now be automatically discovered using process mining through the Automated discovery plugin based on BPMN Miner.
  • Bug-fixing in the model merging function: now merged models obtained from the merging of more than 2 models are configurable.

Version 3.2


  • Log files of process model execution traces in the XES and MXML formats can be animated on top of a BPMN model using the editor’s “Animate logs…” (play) toolbar item.
  • Process models with variants (e.g. merged models or configurable models in general) can show selected variants highlighted using the editor’s “Make selection…” (rainbow) toolbar item.  Highlighting can be performed either on explicit groups of variants, or by frequency.
  • Configurable process models can be converted between the EPML and BPMN formats without having configurability information stripped. This is because now CPF supports configuration elements natively. Configurability information can still only be displayed and edited as BPMN, however.
  • The “Design/Define questionnaire:model mapping” menu item launches the C-Mapper applet for a selected model. This can be used to author .cmap files which define how the answers to a questionnaire in the QML format should configure the variation points of a configurable model. The .cmap files can subsequently be used by the pre-existing Quaestio applet to perform the configuration. With the addition of the C-Mapper to Apromore, a Questionnaire Designer is the only missing part of an entirely web-based toolchain to create and configure process models by questionnaire.
  • Improved handling of BPMN data modeling (Apromore no longer discards BPMN I/O specification elements, and only connects data associations to item-aware elements, rather than directly to flow elements).
  • Bug-fixing in the model merging function: now merged models are configurable.
  • Performance of clone detection has been improved.
  • Apromore can now be built, and Applets can run, under both JDK 7 and 8.
  • Several libraries have been converted into OSGi.

Version 3.1


  • New and improved management of users, this will speed up performance on server side and reduce registration time (in the future user groups will be available we are already working on it).
  • Configurable Process Models. Under Home/BPMN/Airpots we have a set of configurable processes. 
    • If you select one of them and click on Design/Questionnaire-Driven Configuration you will be able to configure the process based on your requirements. You can also create new configurable process models by clicking on Design/Define model: questionnaire mapping. What you need is a questionnaire and a process model with configurable gateways. A gateway can be turn configurable selecting it and tipping  on “configurable” in the right panel). At the moment you can only reuse existing questionnaires or loading them from your local machine. Soon you will be able to create a new questionnaire directly on Apromore (we are already working on it).
  • Apromore knows you. On the top left corner you will receive a welcome with your name every time you login.

  • Even through we have a screen to setup security for users the information isn’t used consistently. The viewing of models uses the info but not the rights to edit or delete.
  • The filtering in Clone detection doesn’t work correctly (decimals not shown, needs ZK 7).
  • The code for clustering clones needs lots of refactoring and the HAC algorithm isn’t working.
  • GED Matrix construction only works against the whole repo not against folders, and so thus the clones clustering that depends upon it.
  • To create a new scheduled task you have write code. UI to create tasks on the fly needs to be implemented.
  • Portal and Manager security needs improvement. The Portal and Manager need to be integrated together so full authentication and authorisation can be supported.
  • Editor has some issues importing and exporting some elements of some languages, e.g. Positions and Objects in EPCs.
  • BPStruct support has some issues, either the json we send is incorrect or BPStruct has an error.

  • Running ZK 6.5.3 CE version now as we didn’t use any EE features. yet.


  • OSGI-ified the rest of the Apromore project (Portal, Manager-Client and supporting projects).
  • Bundled the ZK libraries into a new location, they have to uploaded into your local repo before a build will work now.
  • The start for Spring WS security between the Manager and it’s built client. This is very difficult and could be removed in the future.
  • Upgraded the ZK libraries to the last version 5 release, 5.0.12.


  • Converted the simple graph implementation to use the Canonical Process Format for the GED Matrix Calculations.
  • moved the simple graph implementation into apromore and stripped code to be clean and fast try and help debug any issues.
