Release 3.8 is a twenty sixth midPoint release code-named Watt. The 3.8 release brings major performance and scalability improvements. There are also provisioning, security and user interface improvements.

Release date: 13th June 2018
End of support: 13th June 2020

James Watt (1736 - 1819) was Scottish inventor best known for his significant improvement of the steam engine. Watt steam engine was more powerful and efficient than early steam engines. Those improvements contributed to economic viability of steam engine, which was a crucial element of industrial revolution.

Similarly to Watt's steam engine, midPoint 3.8 brings major improvements to performance, efficiency and scalability. MidPoint 3.8 is designed to handle millions of identities with even higher scaling potential. While fundamental data model of midPoint remains basically the same (and compatible), there were significant improvements to the methods how the data are stored in the database. Handling of the data and especially processing of data changes was also improved. Therefore midPoint 3.8 should be faster. But even more importantly - midPoint 3.8 should be able to work in deployments that were traditionally considered to be beyond the reach of a comprehensive identity management and governance solution.


Majority of the work on the Watt release was done by the Evolveum team. However, this release would not be possible without the help of our partners, customers, contributors, friends and families. We would like to express our thanks to all the people that contributed to the midPoint project both by providing financial support, their own time or those that maintain a pleasant and creative environment for midPoint team. However, midPoint project would not exist without proper funding. Therefore we would like to express our deepest gratitude to all midPoint subscribers that made midPoint project possible.


midPoint 3.8 provides following features:

Changes with respect to version 3.7

Oracle database 11g is no longer supported. It is replaced by Oracle 12c database support.
Support for PostgreSQL 9.4 and earlier is deprecated. PostgreSQL 8.4.x and earlier is no longer supported.
MySQL 5.6 and earlier is no longer supported.
Microsoft SQL 2008 and 2008 R2 are no longer supported. Microsoft SQL Server 2012 support is deprecated.


Release 3.8 (Watt) is intended for full production use in enterprise environments. All features are stable and well tested - except the features that are explicitly marked as experimental or partially implemented. Those features are supported only with special subscription and/or professional services contract.



MidPoint is known to work well in the following deployment environment. The following list is list of tested platforms, i.e. platforms that midPoint team or reliable partners personally tested with this release. The version numbers in parentheses are the actual version numbers used for the tests.

It is very likely that midPoint will also work in similar environments. But only the versions specified below are supported as part of midPoint subscription and support programs - unless a different version is explicitly agreed in the contract.

Support for some platforms is marked as "deprecated". Support for such deprecated versions can be removed in any midPoint release. Please migrate from deprecated platforms as soon as possible.


Web Containers

Currently there are no plans to remove support for deployed midPoint installation using a WAR file. However, it is possible that this deployment form will get phased out eventually unless there are active subscribers preferring this deployment method. MidPoint subscription is strongly recommended if you plan to use this method in the future.

See also "Is Tomcat deployment still supported?" in the Frequently Asked Questions section.


Supported Browsers

Recent version of browser as mentioned above means any stable stock version of the browser released in the last two years. We formally support only stock, non-customized versions of the browsers without any extensions or other add-ons. According to the experience most extensions should work fine with midPoint. However, it is not possible to test midPoint with all of them and support all of them. Therefore, if you chose to use extensions or customize the browser in any non-standard way you are doing that on your own risk. We reserve the right not to support customized web browsers.

Microsoft Internet Explorer compatibility mode is not supported.

MidPoint is software that is designed for easy upgradeability. We do our best to maintain strong backward compatibility of midPoint data model, configuration and system behavior. However, midPoint is also very flexible and comprehensive software system with a very rich data model. It is not humanly possible to test all the potential upgrade paths and scenarios. Also some changes in midPoint behavior are inevitable to maintain midPoint development pace. Therefore we can assure reliable midPoint upgrades only for midPoint subscribers. This section provides overall overview of the changes and upgrade procedures. Although we try to our best it is not possible to foresee all possible uses of midPoint. Therefore the information provided in this section are for information purposes only without any guarantees of completeness. In case of any doubts about upgrade or behavior changes please use services associated with midPoint subscription or purchase professional services.

Upgrade from midPoint 3.0, 3.1, 3.1.1, 3.2, 3.3, 3.3.1, 3.4, 3.4.1, 3.5, 3.5.1, 3.6 and 3.6.1

Upgrade path from MidPoint 3.0 goes through midPoint 3.1, 3.1.1, 3.2, 3.3, 3.4.1, 3.5.1 and 3.6.1. Upgrade to midPoint 3.1 first. Then upgrade from midPoint 3.1 to 3.1.1, from 3.1.1 to 3.2 then to 3.3, then to 3.4.1, 3.5.1, 3.6.1, 3.7.1 and finally to 3.8.

Upgrade from midPoint 3.7 and 3.7.1

MidPoint 3.8 data model is essentially backwards compatible with previous midPoint versions. However, there were changes that may affect some deployments:

Even though the basic database model is compatible with the previous versions, the underlying database schema was significantly modified due to performance and scalability improvements. Therefore the usual database-only upgrade procedure is not applicable for upgrades to midPoint 3.8. Export and import of the data is necessary in this case. Therefore following procedure has be followed for this upgrade:

MidPoint 3.8 is a release that fixes some issues of previous versions and there were also improvements to existing functionality. Therefore there are some changes that may not be strictly backward compatible with previous versions:

Changes in initial objects since 3.7 and 3.7.1

MidPoint has a built-in set of "initial objects" that it will automatically create in the database if they are not present. This includes vital objects for the system to be configured (e.g. role superuser and user administrator). These objects may change in some midPoint releases. But to be conservative and to avoid configuration overwrite midPoint does not overwrite existing objects when they are already in the database. This may result in upgrade problems if the existing object contains configuration that is no longer supported in a new version. Therefore the following list contains a summary of changes to the initial objects in this midPoint release. The complete new set of initial objects is in the config/initial-objects directory in both the source and binary distributions. Although any problems caused by the change in initial objects is unlikely to occur, the implementors are advised to review the following list and assess the impact on case-by-case basis:

Bundled connector changes since 3.7 and 3.7.1

Behavior changes since 3.7 and 3.7.1

Public interface changes since 3.7 and 3.7.1

Important internal changes since 3.7 and 3.7.1

These changes should not influence people that use midPoint "as is". These changes should also not influence the XML/JSON/YAML-based customizations or scripting expressions that rely just on the provided library classes. These changes will influence midPoint forks and deployments that are heavily customized using the Java components.

Known Issues and Limitations

There is a support to set up storage of credentials in either encrypted or hashed form. There is also unsupported and undocumented option to turn off credential storage. This option partially works, but there may be side effects and interactions. This option is not fully supported yet. Do not use it or use it only at your own risk. It is not included in any midPoint support agreement.

Native attribute with the name of 'id' cannot be currently used in midPoint (). If the attribute name in the resource cannot be changed then the workaround is to force the use of legacy schema. In that case midPoint will use the legacy ConnId attribute names (icfs:name and icfs:uid).

JavaDoc is temporarily not available due to the issue in Java platform. This issue is fixed in Java 9 platform, but backport of this fix to Java 8 is (quite surprisingly) not planned.

As all real-world software midPoint 3.8 has some known issues. Full list of the issues is maintained in jira. As far as we know at the time of the release there was no known critical or security issue.

There is currently no plan to fix the known issues of midPoint 3.8 en masse. These issues will be fixed in future maintenance versions of midPoint only if the fix is requested by midPoint subscriber. No other issues will be fixed - except for severe security issues that may be found in the future.

The known issues of midPoint 3.8 may or may not be fixed in midPoint 3.9. This depends on the available time, issue severity and many variables that are currently difficult to predict. The only reliable way how to make sure that an issue is fixed is to purchase midPoint subscription. Or you can fix the bug yourself. MidPoint is always open to contributions.

This may seem a little bit harsh at a first sight. But there are very good reasons for this policy. And in fact it is no worse than what you get with most commercial software. We are just saying that with plain language instead of scrambling it into a legal mumbo-jumbo.
