There are no further changes to the system requirements.

We have installation instructions prepared based on the versions you are upgrading from:

• Upgrade from MAKERS CHOICE 26-07 to MAKERS CHOICE 26-09
• Upgrade from LTS Release Simplifier 10 to MAKERS CHOICE 26-09

If you are setting up a new instance, please follow our installation guide for MAKERS CHOICE 26-09.

Export and delete your v2-Applications

With integration of Anna into Simplifier, the v2 app introduced with MAKERS CHOICE 26-06 also get replaced. Export your v2-Applications and delete them. They will be no longer visible after the upgrade but reserve the technical name if not deleted. (Read more in the migration guide)

Refresh License

Refresh the license on your instances to make sure it is up to date (Read more).

Create AI-Applications for your v2-Applications

Activate the feature ‘AI App Editor’ (recommended to gain the full Anna experience) or ‘AI App Editor (Git only)’ in the Feature Settings and import your export to the new GIT repository. (Read more in the migration guide)

Update Standard Content

Update Standard Content to ensure you have all current fixes and features available on your instances. Update your Apps to OpenUI5 1.148 using our UI5 Upgrade-Wizard. (Download here)

Please check the endpoint of AppWizard Connector, Standard Workflow Connectors, Login, and Captcha Connector (Read more).

Check the deprecated features

Please review all deprecated features and implement any necessary adaptations. (Read more)

[Applications] Create Simplifier tokens via API for users with activated MFA

Currently, you can create tokens with the credentials of Users with activated MFA via our API. This behavior is deprecated due to security concerns. We will remove that feature in the future. You can already deactivate it in the Feature Settings.

Users with activated MFA will not be able to login in to the Simplifier Client or your Business Applications. If you want to enable it also for Business Apps, you have to use a third-party Identity Management Provider like Azure Entra ID.

Deprecated since MAKERS CHOICE 26-09; Removal with a MAKERS CHOICE Release after Simplifier 11. Latest Removal with Simplifier 12

[Integration] Result type in endpoint settings of SQL Connectors

With the integration of calls to the SQL connector, the Result types ‘Single Result’ and ‘No Result’ have been replaced by the output parameters, but have not been deleted yet.

Now it is only possible to create new connector endpoints with the only remaining result type ‘Multiple Results’, and if a Result Type is changed from one of the deprecated types to ‘Multiple Results’, it cannot be changed back.

Note: As soon as we delete this feature, we will migrate all remaining calls to the ‘Multiple Results’ result type.

We encourage you to already deactivate the simple mode to be used in new / changed calls in the Feature Settings. If the setting is deactivated, existing calls will use the ‘Multiple Results’ result type. Use the ‘Show usage’ button to get all a list of all connectors that still use the deprecated result types.

Deprecated since MAKERS CHOICE 26-07; Removal with a MAKERS CHOICE Release after Simplifier 11. Latest Removal with Simplifier 12

[Integration] Simple mode in SQL Connectors

The simple mode in SQL Connectors is redundant to query and execution mode and will be deleted in a future Release. Please change your existing configurations to either query or execution. As the behaviour might change for the connector call’s result when changing the call’s mode, we cannot provide a default automated migration.

Note: As soon as we delete this feature, we will migrate all remaining calls to the query mode.

We encourage you to already deactivate the simple mode to be used in new / changed calls in the Feature Settings. If the setting is deactivated, existing calls with simple mode can still be used. Use the ‘Show usage’ button to get all a list of all calls that still use the simple mode.

Deprecated since MAKERS CHOICE 26-06; Removal with a MAKERS CHOICE Release after Simplifier 11. Latest Removal with Simplifier 12

[Integration] Support of CryptoJS in Server-side Business Objects

The active development of CryptoJS ended a while ago. For security reasons, the CryptoJS integration will be removed from Simplifier.

For server-side business objects, there will be no direct replacement. We provide replacements within the Simplifier SBO API for selected CryptoJS APIs instead, starting with AES encryption and SHA256 hashing. On-premise customers with use-cases not covered by these should contact us (for Simplifier-hosted customers, we will check CryptoJS usage automatically).

If you need client-side crypto functionality, we recommend using the available JS Web Crypto API.

You can already deactivate CryptoJS in the Feature Settings.

Deprecated since MAKERS CHOICE 26-04; Removal with a MAKERS CHOICE Release after Simplifier 11. Latest Removal with Simplifier 12

[Integration] Global API objects (capital letters) in Server-side Business Objects functions

Currently, you can still use the redundant and outdated global Business Object API with the prefixes CONNECTOR_, BUSINESSOBJECT_, PLUGIN_, LOG_, TOOLS_, and USERS_. Their usage is deprecated and will be removed in the future. Use the Simplifier SBO API instead.

You can already deactivate the global objects in the Feature Settings.

Deprecated since MAKERS CHOICE 26-04; Removal with a MAKERS CHOICE Release after Simplifier 11. Latest Removal with Simplifier 12

[System requirements] Support of Oracle for Simplifier databases

Oracle support for your Simplifier instances has been deprecated and will be removed in a future release.

Deprecated since Simplifier 8 EHP 4; End of support with a MAKERS CHOICE Release after Simplifier 11. Latest end of Support with Simplifier 12

[Integration] Client 1.0 API route to access Proxy-Connector

Our new Proxy Connector will be accessible via the Client 2.0 route (Read more). Starting with MAKERS CHOICE 25-10/Simplifier 10, all old Proxy Connectors are migrated to the new one. Until Simplifier 11, the Client 1.0 route is still available. If you use it in Scripts, Client-side Business Objects, or REST-Connectors, please change it to the Client 2.0 route to keep accessing your Proxy Connectors.

Deprecated since MAKERS CHOICE 25-08; Removal with a MAKERS CHOICE Release until Simplifier 12/Removal with Simplifier 12

[Integration] Javascript execution in PDFs created by PDF Plugin

Currently, it is possible to add Javascript to PDFs created by PDF Plugin. This is a potential risk for Server Side XSS (PDF Injection) and Server Side Request Forgery (SSRF). The option to add Javascript to PDFs in PDF Plugin is now deactivated but can be activated at its own risk. The activation is subject to be removed in later Releases.

Deprecated since Simplifier 8 EHP 3; Removal tbd

[Integration] Removed setting to activate deprecated Connector API

The settings to activate deprecated Connector API will be removed with Simplifier 10 LTS. Please make sure you do not use the deprecated Connector API anymore.

Deprecated since Simplifier 8 EHP 4; Removal tbd

[AI] v2 Apps

The v2 Apps had been a first experimental feature to enable AI based application development in Simplifier. With our integration of Anna into Simplifier, Ai based development gets a lot easier. External AI development is still possible but adapted to enable Anna to also work with the results of the external development.

Simply migrate your applications as described in the migration guide.

Removed with MAKERS CHOICE 26-09

[Integration] The limit parameter of the OData SBO API query function has been replaced

The OData connector integration in the SBO API is still experimental and gets constantly improvements. During that, we replaced the query function’s limit parameter and replaced it with dedicated functions top() and skip() for limiting the result set. (Read more)

Removed with MAKERS CHOICE 26-09

[Integration] Captcha Plugin

Our Captcha Plugin won’t be updated anymore and was removed from the plugin list in our default installation/upgrade guides.

See our Knowledge Base article on ‘How to use Google reCAPTCHA v3 Essentials‘ for an alternative solution.
