Between 2023 and early 2025, Adtelic published a run of articles on Umbraco, Optimizely, Sitecore, and digital experience platforms in general. They came out of platform work we were doing at the time: release summaries, pricing and scalability questions, comparisons that clients kept asking for.
That work is not what Adtelic does now. Since 2026 the practice is applied AI for associations and nonprofits, and we no longer extend or update the platform articles. We keep them because people still find them useful, and because a release note from 2024 is still a release note from 2024.
This page is the index. Every article below is dated by its subject. Treat version numbers, pricing, and roadmap items as historical. If you are evaluating a platform today, the vendor’s current documentation outranks anything here.

Where the platform question goes now
The platform question has not gone away for associations. It has moved. The AMS vendor is adding AI features to the platform you already run, the CMS is adding generated content, and the question is no longer which DXP to license but what each vendor can do with member data once the feature is switched on. That is the question the buyer’s guide to AI, ML, and data products answers, and it is what the AI readiness audit assesses.
