Agent version history, new models, and a clearer workspace trail

Here's what shipped in September so far, plus a look at what's taking shape next.

Agent Version History: See what changed on an agent, then roll it back

An agent's instructions can change several times before anyone notices its answers have shifted. Agent version history lets you review saved configurations, see who changed them and when, and inspect highlighted text changes.

Preview an earlier version and restore it if you have edit access. Restoring creates a new current version, so the original history stays intact.

Audit Trail: Trace activity down to the resource

When something changes, you need to know who did what and where.

The Audit Trail's new Workspace activity view records activity on knowledge bases, agents, skills, projects, and automations, plus connections and integration syncs.

Search by resource or person, filter events, and open a resource's history.

Access on request: TextCortex needs to enable workspace activity logging for your tenant. Contact your account manager to request access.

Browse knowledge bases by folder

A flat file list makes familiar documents harder to find.

Folders are supported with synced knowledge bases from SharePoint, OneDrive, and Box. This view now lets you navigate through folders and subfolders. (More integration support is on the way.)

Open a folder, follow the breadcrumb back, and switch between list and grid views. You don't have to work through the entire knowledge base to reach the folder you need.

Find the replacement for your retiring model

Retiring models shouldn't leave you guessing what to choose next. Here's where to move:

Opus 4.7 & 4.8 → Opus 5.
Sol 5.6 → Sol 6.1.
Sonnet 4.6 → Sonnet 5.5.
Gemini 3.5 & 3.6 → Gemini 3.8 Flash.
GLM 5.2 → GLM 5.3.
Kimi K2.6 & K2.7 → Kimi K3 (Premium) or GPT-6 Luna

For enterprise admins: If the replacement model is already enabled, agents using the older model will upgrade automatically. Otherwise, the replacement stays disabled until an enterprise admin enables it, and the agent falls back to the tenant default model.

Gemini 3.8 Flash and Claude Haiku 5.5 join the catalog

Checking which models your team can use shouldn't take a release-note hunt. We've added Gemini 3.8 Flash and Claude Haiku 5.5 to the model catalog, so you can review them alongside your existing choices.
