As you know, we utilize the LGPLv3 license to publish the Alfresco Community. In this blog article, I will explain the basics of this license: why Free Software Foundation created it; a bit of its history; how it applies in the real world for developers, integrators, and application builders; and best practices for legal compliance of your projects.

This blog post describes the support for ARM64 Docker Images in Alfresco 7.3.

Mac computers using Apple Silicon chips should use this architecture for Docker Images.

Alfresco Content Services 7.3 is a minor software update release with improvements to Alfresco Content Services to accelerate use and development for customer solutions for deployment. With Alfresco Content Services 7.3, Alfresco continues to enable open source communities, customers and partners to deliver a highly reliable Content Store upon which to build applications and solutions.

Alfresco Search Services indexes PATH values from Repository using the CascadeTracker. Once the metadata and content has been indexed, some components (like the Enterprise Admin Web Console for the Enterprise version) will report that no indexation is happening. But CascadeTracker is still catching up with the Repo to get the paths indexed. This blog post will give you some tools to check the status of the PATH indexation.
