1515* As a precaution following the publicly reported compromise of several emSign (eMudhra) intermediate certificate authority (CA) keys, most of the connections Claude Science makes itself, and many of the package installs it runs itself, no longer trust emSign (eMudhra) root certificates or one other root certificate. Versions 0.1.69 and later include all of these changes; to update, see [Update Claude Science](https://claude.com/docs/claude-science/update-claude-science.md)
16* [Auto mode](https://claude.com/docs/claude-science/auto-mode.md) is on by default wherever it's available to you: it lets Claude Science run code and call connectors without stopping to ask about every step. Turn it off for new sessions in **Settings > Permissions**, or for one session in its settings menu in the message box
17* Auto mode: if **Auto mode on for new sessions** is off, then in the Windows app, or when Claude Science runs from a terminal or in a browser tab, turning auto mode on for a single session may not take effect until you quit Claude Science fully, reopen it and turn the session on again, usually once for each organization. To quit it fully, see [the steps in Troubleshoot Claude Science](https://claude.com/docs/claude-science/troubleshooting.md#environments-failed)
18* Team and Enterprise: auto mode works only where it's allowed for your organization. Where it isn't, the **Auto mode on for new sessions** toggle is grayed out (point at it to see why), and Claude Science asks for approval as it does without auto mode
1619* A new **Trouble updating?** link opens [Update Claude Science](https://claude.com/docs/claude-science/update-claude-science.md), a help page with other ways to update. It shows in **Settings > General > About**, in the **Update required** box, and on the "Update available" notice while an update downloads or after one fails
1720* Cloud storage in Settings now works with Google Cloud Storage HMAC keys on computers where no AWS region is set
1821* Mac: if `config.toml` has `auto_update = false` under `[update]`, Claude Science in its own window no longer checks for updates in the background. You can still check with **Claude Science > Check for App Updates…** in the menu bar
