Stacked pull requests, real-time diffs, and AI credit management

Stacked pull requests are now displayed in Linear Diffs. Move through a stack and see review, CI, and merge status at a glance. Related PRs are grouped into a single collapsible row in Reviews, alongside their issue and project context. For GitHub-native stacks, you can preview every affected PR before merging the current PR and those below from Linear. Learn more in our documentation. View code changes as the agent works Diffs now update in realtime throughout a Linear coding session, including uncommitted changes from follow-up prompts. You can follow the code as it evolves, catch wrong turns earlier, and steer the agent before or after a pull request is opened. AI credit usage explorer and spend limits Admins can now see what’s driving AI credit usage and set limits to manage spend. The new usage explorer breaks down spend by team, feature, user, or loop across any time period. Compare total spend, session count, and average spend per session, then select a group in the chart or table for a closer look. You can also set spend limits at the workspace, user, or loop level to keep usage within the bounds you choose. When a limit is reached, additional AI credit usage is paused until the limit resets or an admin increases it. Billing admins and owners can access both features in Usage & Limits. Learn more about AI credits in our documentation. Guided Reviews on Basic Guides walk you through the most important changes in a pull request. They’re now available on Basic plans.
