6 * Saved credentials now reach Claude's code only when it asks for them and you approve. They're no longer present in every cell
7 * Access Claude Science work saved on your computer from other sign-ins, from Home or Settings. Admins control it on Team and Enterprise plans
8 * Claude can send you a short message, such as a link to a file, while it keeps working on a task
9 * Mac: Apple silicon Macs with the Intel version installed can now update, and then run natively
10 * Mac: if Claude's tools can't start after an Xcode update, the error now says how to accept the Xcode license
11 * You can comment on and bookmark the short summaries of Claude's progress notes
12 * Sessions moved to a model with a smaller context window keep going instead of failing
13 * Turning Auto-review off now applies to agents that are already running; turning it back on resumes their reviews
14 * Settings > Connectors shows "Not set" for tools without a permission, and saves "Ask each time"
15 * Windows: `claude-science install` now reports the step that failed instead of reporting success
16 * Faster search of a long session's history; clearer wording in model settings
