# Claude Science changelog > Release notes for Claude Science, including new features, improvements, and bug fixes by version. <Update label="0.1.27" description="August 7, 2026"> * On macOS, installs that showed an environment setup error in their first session now repair themselves automatically after updating; the Featured connectors become available once the repair finishes, which can take a few minutes * Star a session from its menu to keep it in a Starred section at the top of your project's session list * Get notified when any of your sessions finishes or needs your input, even while you work in another project. In-app notifications are on by default; sound and desktop notifications are under Settings > General > Notifications * Set reasoning effort for a single session from the session options next to the message box; the value in Settings stays the default for new sessions * On Pro and Max plans, see your credit balance and monthly spend limit and turn usage credits on or off under Settings > Usage * When you ask for a plan, Claude now waits for your approval before running code or marking steps done * Lots of other miscellaneous improvements and fixes </Update> <Update label="0.1.21" description="July 21, 2026"> **New** * **Improved context preservation.** On Max, Team, and Enterprise plans, sessions go much further before older messages are summarized. * **Works on corporate networks.** Sign in and install packages on networks with corporate proxies, TLS inspection, or authenticated package mirrors. Mirror credentials go in Settings. No config files needed. * **Search your memories.** Find anything Claude remembers from the memory screen. Results are highlighted and jump to where they live. The screen also loads faster now. * **Archive projects.** Tidy your project list without deleting anything; archived projects keep all their data and can be brought back anytime. * **Password sign-in for SSH machines.** Adding a remote machine that asks for a password instead of a key is now supported. You're prompted when it's needed, and the password is never saved to disk. * **Compute monitor.** See every running kernel with its memory and CPU use from the new Compute tab. Kernels can be stopped if needed with optional feedback sent to the agent such as "redo this analysis using less memory". **Improvements and fixes** * **Richer artifact previews.** HTML files show rendered thumbnails, Word documents show text previews, large CSVs show their structure, and PDFs show their first page. * **Parquet files open as tables.** See a parquet file's columns and first rows right in the app, even for very large files. * **Memories stay in their project.** Notes from one project no longer surface in another. * **Annotations travel with your message.** Annotations you've added appear above the message box and carry over when you open a side chat. * **Less disk space for huge files.** When Claude saves the same very large file over and over, it can now keep just the latest version instead of every copy. * **The conversation view holds still.** Images no longer shove the page as they load, "View in context" lands on the right message, and mentioning a file always attaches the right one. * **Edit messages with attachments.** Editing an earlier message now supports file mentions, attachments, and uploads. * **Many other miscellaneous fixes and improvements.** </Update> <Update label="0.1.18" description="July 9, 2026"> **Features** * Sessions now pause and ask for your confirmation before spending extra usage. Billed usage credits are never drawn on a dismissible warning alone. * Claude can now monitor how much memory and processing power its computations are using, and plan its work accordingly. * Search from inside a project: the project view now has a search button that opens the same search as Cmd+K. * Download any artifact from any surface: every artifact menu now includes a download option. * Starred artifacts now pin to a new Starred section at the top of the Library, with a star badge. **Fixes** * Fixed a crash that could prevent very large sessions from loading. * Fixed several ways a running session could stall or stop early, including long thinking pauses being cut off mid-run and sessions resuming incorrectly after a crash. * Fixed the app sometimes becoming unresponsive after an automatic update. * Code blocks now switch correctly when your system switches between light and dark mode. * Lots of other miscellaneous improvements and fixes. </Update> <Update label="0.1.17" description="July 8, 2026"> * **Fixed a bug where idle sessions were consuming usage.** * Lots of other miscellaneous improvements and fixes. </Update> <Update label="0.1.16" description="July 7, 2026"> **Features** * Auto-review is now available on the Pro plan: turn it on from the session settings, and it stays off until you do. * Artifact previews: zoom HTML artifacts (including fit to width), zoom images to native resolution, and choose which version an artifact diff compares against * Import skills from private GitHub repositories using your own GitHub credentials * LaTeX previews now resolve cross-references — \ref, \eqref, and section numbering render the way your document intended * Dashboard upgrades: a project switcher with live per-project status, project names on the "Now" cards, a visible search button, and ⌘K search now matches project descriptions too * Annotate artifacts faster: drag image annotation pins to reposition them, and use @/# mentions in annotation comments **Fixes** * Pasted attachments no longer disappear before their first use, very large text and JSON previews no longer freeze the tab, and a stale usage-limit banner now clears itself once your usage limit resets * Cloning a repo or unpacking an archive no longer floods the chat with every image it contains * The Reviewer no longer gets stuck on "Reviewing…" or hides its findings tray * Flaky read-only connector tool calls now retry once automatically instead of failing your turn, and connector setup errors tell you what's actually wrong * A corrupt pasted image no longer breaks the transcript * Upgrading with a very large history database no longer fails partway through * Fixed a crash when the browser's auto-translate feature modified the page * Lots of other miscellaneous improvements and fixes </Update> <Update label="0.1.15" description="July 1, 2026"> * Corporate networks: environment builds now work behind TLS-inspecting proxies (such as Zscaler or Netskope). On macOS, corporate root CAs in your keychain are picked up automatically for conda/pip package downloads; on macOS or Linux you can also point at a CA-bundle file under Settings > Network > Package mirror. The mirror card's Check button now verifies TLS trust with the same bundle the builds use. (In-session `pip`/`curl` and the Desktop app's guest-VM builds are not covered) * Package mirrors: point conda and pip at your organization's internal mirror (Artifactory/Nexus) via Settings > Network > Package mirror. Setting a mirror also drops the public package hosts from the sandbox network allowlist * OpenAlex now requires a free API key for full-text access. Claude Science resolves access automatically or asks you in the session when a key is needed; you can also add and validate a key anytime under Settings > Credentials * New Context usage view: see how full a session's context window is and where tokens go, from the + menu in the composer * Lots of other miscellaneous improvements and fixes </Update> <Update label="0.1.14" description="June 30, 2026"> * Public launch of Claude Science </Update>
