What's New in Claude · Updated 30 October 2026

# Every Claude release, and what it means for _your company_.

Anthropic ships something most weeks: a model, a feature in the Claude apps, a change to the API or to Claude Code. Most of it does not matter to a company. The releases that do are below, newest first, each one with what changed, what it means and what to do that week.

The facts come from Anthropic’s own release notes and announcements, linked on every post. The view on what it means is ours, from the firms we work with as a member of Anthropic’s [Claude Partner Network](/announcements/by-the-people-technologies-joins-claude-partner-network). For the bigger question behind all of them, start at [How will Claude affect my business?](/claude)

How we write these

## Sourced, checked, and signed.

Every post starts from Anthropic’s published sources: the Claude Platform release notes, the Claude apps release notes, the Claude Code changelog and Anthropic’s announcements. Every price, date and figure on a post is the vendor’s own and is linked at the bottom of the page.

Each post is drafted with Claude from those sources, then checked against them, figure by figure, before it goes up, and anything the check cannot confirm waits for a person at the firm to read it. Where we have tested a release ourselves, the post says what we ran and shows it; where we have not, it says nothing about testing at all.

Questions

## Questions about Claude releases.

Answered in full, so the answer is here when you need it.

### Where does Anthropic publish Claude release notes?

In four places: the Claude Platform release notes for the API and Console, the Claude Help Center release notes for the Claude apps, the CHANGELOG in the claude-code repository on GitHub for Claude Code, and anthropic.com/news for announcements. This page collects the releases that matter to a company from all four.

### How often does Claude get updated?

Most weeks. Between 16 September and 8 October 2026, Anthropic merged Claude chat and Cowork, released Claude Opus 5.5, Sonnet 5.5 and Haiku 5.5, launched Claude Docs, Slides and Design, and put Dashboards and Motion into beta. Each has its own post on this page.

### What is the latest Claude model?

As of 30 October 2026, the current models are Claude Fable 5.1, Claude Opus 5.5, Claude Sonnet 5.5 and Claude Haiku 5.5. Anthropic's documentation recommends starting with Opus 5.5 for most work.
