Alfresco Community Edition 7.0

Alfresco Community Edition 7.0 is our latest Open Source software release that has improvements to Alfresco Content Services which accelerate development of business solutions. With Alfresco Community Edition 7.0, Alfresco continues to enable open source communities, customers and partners to realize value from their most important information.

Alfresco Community Edition 7.0 delivers functionality to enable developers and customers to customise the product and extend through integrations. Customers can purchase an upgrade from Alfresco Community Edition to Alfresco Content Services 7.0 for advanced features and support of our for-fee Alfresco extensions and applications.

Alfresco Community Edition 7.0 shares much of its code with Alfresco Content Services 7.0 release. This release contains core functionality enhancements completed from the release of Alfresco Content Services 7.0. In addition this release contains an updated stack of supported databases, operating systems and platforms providing up to date support.

The release readiness testing team have successfully completed their regression testing cycles to help give you confidence. 

Goals for this Release

The main goal of this release is to enable customers to create solutions. As Alfresco and Hyland have a continuing commitment to Open Source, we value your feedback.

 Use Cases

  • Provide new features to allow partners and customers to create solutions.

  • Support customers using the Open Source version of our major products and components.

  • Support partners doing open source development for customisations for their customers.

  • Support customers in open source development.

  • Assisting partners and customers to migrate customisations from previous releases to Alfresco Community Edition 7.0.

We have changed the way the Community Edition should raise issues which we anticipate will make it easier to raise issues and manage them. Please report issues with this Alfresco Community Edition 7.0 using GitHub Issuesor by using the discussion tools in this social Community Edition.

Upgrading from previous releases

Care should be taken when upgrading from any previous releases of Alfresco Community Edition 7.0. There are some steps that should be reviewed and planned before you upgrade. Please take the time to familiarize yourself with the guidance below and plan your upgrade.

Please refer to the detailed Upgrading documentation, including Alfresco Content Services upgrade paths.

In particular, please ensure that the following steps are completed before you start your upgrade process:

Specific Release Components

Content Repository

  • New REST API Endpoints:

    • File Version Rendition Management API is now available under /nodes/{nodeId}/versions
      POST '/nodes/{nodeId}/versions/{versionId}/renditions'
      GET '/nodes/{nodeId}/versions/{versionId}/renditions'
      GET '/nodes/{nodeId}/versions/{versionId}/renditions/{renditionId}'
      GET '/nodes/{nodeId}/versions/{versionId}/renditions/{renditionId}/content'

    • Site Membership Management API is now available under /sites
      GET '/sites/{siteId}/group-members'
      POST '/sites/{siteId}/group-members'
      GET '/sites/{siteId}/group-members/{groupId}'
      PUT '/sites/{siteId}/group-members/{groupId}'
      DELETE '/sites/{siteId}/group-members/{groupId}'

    • Model API: https://develop.envalfresco.com/api-explorer/?urls.primaryName=Model API

  • Metadata Extract

    The out of the box extraction of metadata is now generally performed asynchronously via a T-Engine connected to the repository as a Local transformer or as part of the Alfresco Transform Service, which is available in Alfresco Content Services. This provides better security, scalability and reliability. The framework used for metadata extraction within the content repository remains, allowing custom extractors / embedders of metadata to still function, as long as they don't extend the extractors that have been removed. Ideally, such custom code should be gradually moved into a T-Engine. For more information see Metadata Extractors.

  • Removal of 3rd party libraries

    With the offloading of both transforms and metadata extraction to T-Engines a number of 3rd party libraries are no longer needed within the content repository. They do still exist within the T-Engines performing the same tasks. Any AMPs that were making use of these will need to provide these libraries themselves. This will reduce the footprint of the repository and allow more frequent releases of the T-Engines to take advantage of new functionality or security patches in these libraries.

    • PdfBox org.apache.pdfboxSmiley Tonguedfbox:2.0.21 removed - transforms are now performed in T-Engines

    • PdfBox org.apache.pdfbox:fontbox:2.0.21 removed - transforms are now performed in T-Engines

    • PdfBox org.apache.pdfboxSmiley Tonguedfbox-tools:2.0.21 removed - transforms are now performed in T-Engines

  • Removal of legacy transforms from Content Repo
    The Alfresco documentation, Transform Service vs. Local and Legacy Transforms provides a summary of the transforms provided in recent ACS versions.  Due to investment in the Transforms Service and Local Transforms, this release deprecates the availability of Legacy Transforms. The code that supports “legacy transforms” within ACS Repo has been removed.  The Legacy Transforms are replaced fully with the Transforms Service and out-of-process Core Transform Engines.

  • Core All-In-One (AIO) Transform Engine

    We have previously introduced T-Engines for Alfresco Community Edition and Alfresco Content Services that run in separate processes. For Alfresco Community Edition deployments it is recommended to run the AIO T-Engine in a single JVM.  In addition, the AIO solution has been updated at Alfresco/alfresco-transform-core with the option to build a single AIO T-Engine. The Core All-In-One (AIO) Transform Engine combines the current 5x core T-Engines (LibreOffice, ImageMagick, Alfresco PDF Renderer, Tika) packaged together into a single Docker image.  Deployments requiring greater scalability in these situations the individual T-Engines will be preferable available in Alfresco Content Services. 

  • Events related to node and association actions
    In Alfresco Community Edition 7.0 the Content Repository publishes events related to an initial set of actions to nodes and associations. This is the first time that this feature is introduced as part of the ACS Core Services, and it will be used in many use cases, as an example by the Alfresco Event SDK. For the moment the supported events are related to node creation/update/deletion, secondary child association creation/deletion, peer association creation/deletion.

REST API Explorer

REST API Explorer is integrated into alfresco-repository-Community Docker image. It is accessible via the link provided in the /alfresco page either via using /api-explorer context on alfrescoServerPath (alfrescoScheme://alfrescoHost:alfrescoPort).

 to navigate the details of the new REST API endpoints.

  • We have migrated Swagger-UI 2.0 to Swagger-UI 3.0, which is compatible with both OpenAPI 2.0 and OpenAPI 3.0

There is a new Alfresco Event SDK for out-of-process events (SDK v5.0), which is compatible with Alfresco Community Edition 7.0.

Alfresco Extension Inspector

A new utility has been created to help partners and customers better understand the customisations in their existing deployments. The Alfresco Extension Inspector is a utility for AMP inspection for Alfresco Community Edition and Alfresco Content Services 5.2.7, 6.2.2 and 7.0.0. The inspector is recommended for use before installing new versions of our product to help expose any issues that might impede success.

The alfresco-extension-inspector is a tool that scans and validates an Alfresco extension (amp or jar) against an alfresco.war file. The tool parses an extension and generates a report on possible overrides, discouraged usage of nonpublic API, Alfresco's 3rd-party libraries and incompatible libraries.

To download Alfresco Extension Inspector from Nexus click here or from GitHub.

Issues Addressed

We have addressed a number of defects since the last release, whilst we don’t report on all issues we have provided a JQL for resolved issues.

This Issues Addressed query provides a summary but does not differentiate Alfresco Content Services from Alfresco Community Edition.

Known Issues

  • AGS 3.5 compatibility with Alfresco Community Edition 7.0 is targeted in the late April 2021 time frame

  • Alfresco Content Services 7.0 contains a recommended database patch which is not automatically applied during upgrade, as the amount of time needed to create new indexes might be considerable. Details are included in the upgrade documentation.

    Until this step is completed, you will see Schema Validation warnings reported in the alfresco.log on each startup. The log will also indicate that the patch was not run.
