Agentic AI Platform Change Log

Agentic Index tracks material changes across agentic AI platforms, including new agent capabilities, workflow orchestration updates, integrations, MCP/tool-calling changes, memory features, human approval controls, observability, deployment options, pricing, funding, and verification-status updates. This change log is the index that tracks changes to agentic AI platforms, updated weekly. If you are trying to keep up with changes to AI agent platforms without reading every vendor's release notes separately, this is the feed to read.

Public-source research. All entries are sourced from official vendor blogs, changelogs, documentation, or press materials. Support levels marked Needs Review or Publicly Claimed should be independently verified before relying on them for procurement decisions.

Memory / state

Letta released the open-source trajectory package, which normalizes coding-agent sessions from Claude Code, Codex, and Letta Code into a single JSON-compatible format. The schema captures user messages, agent reasoning, and tool results while stripping redundant payloads to reduce token usage by up to fivefold.

Teams using multiple agent harnesses can now aggregate session data into a standardized format. This structure powers Letta's background dreaming process, allowing agents to extract lessons from past experiences across different tools and write them into persistent memory.

Common questions

How do I keep up with changes to AI agent platforms?

Read one maintained change log instead of tracking each vendor's release notes separately. The Agentic Index change log records 981 verified updates across agentic AI platforms, updated weekly, covering new agent capabilities, MCP and tool calling changes, memory, human approval controls, observability, deployment options, pricing and funding. Every entry names the vendor, the date, the change type and an impact level, and links to that vendor's profile.

How often is the agentic AI change log updated?

Weekly. The most recent update was Sep 4, 2026, covering LivePerson, Serval, ServiceNow.

How do I track changes for one specific AI agent vendor?

Filter the change log by vendor, or open that vendor's profile page, where the same verified entries appear alongside its capability coverage across the 14 point Agentic Index taxonomy.

Where can I find a single feed of agentic AI platform updates?

This page is that feed. Agentic Index reviews vendor blogs, changelogs, documentation and press materials every week and files what materially changed, so keeping up with changes to AI agent platforms is one page rather than several hundred. Entries are filterable by vendor, change type, impact level and verification status, and each one carries the evidence basis it was graded from.
