44
5<Update label="0.1.51" description="September 22, 2026">
6 * Pinned sessions (formerly starred) from across all your projects now appear at the top of the session list; a new switch in **Settings > General > Appearance** lets you limit them to the open project
7 * In Markdown files, click a plain-text cell in a table to edit it in place
8 * Tables in Markdown files keep their scroll position when Claude saves another file
9 * Fixed the BioMart connector's data queries and identifier translation; a data query that filters on more than a few hundred IDs can still fail
10 * The BioMart connector now reads from Ensembl's June 2026 archive. If your network allowlist lists `www.ensembl.org` by name, add `jun2026.archive.ensembl.org`
11 * Removed connector tools that failed on every call: the ENCODE and eQTL Catalogue lookups and ZINC's random-sample tool
12 * "Download script" on an artifact made by a shell command now includes the script itself
13 * The app stays more responsive while Claude saves files in projects with tens of thousands of files, and zip downloads with thousands of same-named files are prepared much faster
14 * Mac: security hardening of the analysis sandbox
15 * Life Sciences Verification Program (beta): fixed a case where your approved use cases could disappear from the app
16 * Various bug fixes and security improvements

519<Update label="0.1.50" description="September 17, 2026">
620 * Tables in Markdown files now show as a compact grid; a long table keeps its header row in view, and row labels stay in view when you scroll sideways
721 * Tabs in the right pane can be reordered by dragging, or with Ctrl/Cmd+Shift+Left/Right

99Claude Science includes Featured connectors to public life-sciences databases. They're on by default and can be turned off individually in **Settings > Connectors**. On Team and Enterprise plans, your organization can also turn individual Featured connectors off for everyone, and in organizations with HIPAA compliance enabled they start off until an admin turns them on. A connector your organization has off stays listed, grayed, and Claude can't use it (see [Featured connectors and skills](/docs/claude-science/admin-controls#featured-connectors-and-skills)). Featured connectors are read-only and don't require an account or key. Some underlying databases have non-commercial or attribution terms; review each source's license for your use case.

1515## Versions
1616
17When Claude saves the same filename again in the same session, the artifact gains a new version. You can also edit text-based artifacts (Markdown, code, plain text) directly: click **Edit content**, make changes, and **Save** to create a new version. Images, PDFs, HTML, and tables can't be edited in place.

You can also edit text-based artifacts (Markdown, code, plain text) directly: click **Edit content**, make changes, and **Save** to create a new version. In a Markdown file, you can click a plain-text cell in the body of a table and type, and the app saves the change as a new version. Images, PDFs, HTML, and table files such as CSV can't be edited in place.
1818
1919When an artifact file is open, a version stepper and a diff toggle appear. In diff mode, you can choose which earlier version to compare against; the previous version is the default. Older versions are read-only; to restore one, ask Claude to save it again. Links Claude puts in the conversation point to the specific version that existed at the time.
