Staying Current with Platform Changes

Overview

Sulus is under continuous development: new AI models and voices are added, APIs are refined, and older features are occasionally deprecated or retired in favor of better replacements. This page explains the kinds of changes you can expect to see documented over time, using a few real, representative examples, so you know what to watch for and how to plan around it — rather than being surprised by a change after the fact.

Note: a dedicated, continuously updated public changelog page is not yet live on this documentation site. Until it is, the categories and examples below reflect the kinds of changes the platform has made historically, and your Sulus representative or [email protected] can confirm the current state of any specific feature.

Platform changes generally fall into a few categories:

• New models & voices — additional LLM providers/models or voice options become available for your assistants to use
• API changes — new endpoints, new versions of existing endpoints, or new optional fields on existing objects
• Breaking changes — a change that requires you to update your integration or configuration to keep working correctly
• Deprecations & retirements — advance notice that a feature, endpoint, or option will stop working on a specific date, along with the recommended replacement

Breaking changes and retirements are the ones worth paying closest attention to, since they come with a deadline — for example, Workflows are being retired on August 18, 2026 in favor of Assistants and Squads (see Workflows to Squads Migration), and several legacy voices were retired on March 1, 2026 (see Legacy Voice Retirement & Migration).

These examples illustrate the kind of information you'll find in release notes, drawn from real platform changes:

Until a live changelog page is published here, the most reliable ways to stay current are:

• Check the documentation pages for the specific feature you rely on (Assistants, Squads, Workflows, Voices, Models) for any deprecation or retirement notices called out directly on that page
• Watch for advance notice emails from Sulus about upcoming breaking changes or retirement dates
• Ask your Sulus representative or reach out to [email protected] if you want to confirm whether a specific endpoint, model, or voice is still supported before you build against it

In summary: expect changes in four broad categories — new models/voices, API changes, breaking changes, and deprecation/retirement notices — and treat any retirement notice with a stated date (like the Workflows retirement or the March 2026 voice retirement) as a hard deadline to migrate before.
