Released 16 October 2026.

Desktop app

Newa tour of Studio, offered when you finish onboarding
Newthe Renders tab shows what re-renders, what caused it, and which providers trigger extra renders, and warns you about render loops. The Inspector's Perf tab is now Renders too, and the component tree highlights each re-render
NewStudio checks performance while you use the app, and tells you about each new problem once
NewInsights can group recent sessions, so a problem that keeps coming back is one card
Newthe Performance screen opens on a dashboard
NewCompare puts several metrics on one chart, with presets. Hover a metric to see what it measures
NewReplay charts show CPU per thread, dropped frames, garbage-collection pauses and network
NewReplay draws a recording's touches over the device, and the heatmap follows the playhead
Newcapture a CPU profile from the Flamegraph panel with one button
Newthe device menu lists running Mac apps
Newnotifications survive a restart, and clicking one takes you to what it's about
NewHardware → Shake shakes the simulator
FixStudio uses less CPU, and animations and tooltips run at the right speed

Fixhovering a row in the component tree outlines that component on the device
Fixexpanding a row in the Network panel no longer shows an error
Fixa restarted run's charts no longer start with a sample from the previous run
Fixtaps made by a flow or an agent no longer count as rage taps or dead zones

Breakinginstall-macos-agent.sh is gone. Squiggle adds the agent to your Mac app's Debug build for you, so remove any build step that runs the script
Newsquiggle init finishes setting up an Expo app, adding the Babel config and entry file if they're missing. Anything it can't change safely, it lists for you to do
Newsquiggle init no longer creates a .env file. Your iOS app finds Squiggle without one
Newsquiggle init --agent claude also installs the Squiggle agent kit into .claude/
Newsquiggle doctor also checks your licence and the Babel plugin, and says how to fix either
Newwhen your trial or licence expires, Squiggle tells you where to buy a key

Fixtwo runs started at the same moment no longer merge into one history entry

Newrenders gives your agent what Studio's Renders tab shows
Newpropose_fix turns a performance finding into a plan of code changes
Fixbatch checks every step before it runs any, so a malformed step no longer runs the steps before it
Fixafter a filtered describe, the next action no longer reports elements that were already on screen as new
Fixa tap by ref hits that element, even when another one has the same label
Fixthe agent kit's Claude Code hooks run

Breakinga misspelt key at the top of a flow file, such as healng:, is an error that lists the valid keys. It used to be ignored
Newtest an iOS app and a Mac app from one project: list both under apps in the config, and pick one with --platform. squiggle init fills them in
Newresults are kept per platform, so a flow that passes on iOS isn't counted as passing on macOS
Newsquiggle flow --record works for Mac apps
NewMac apps with App Sandbox turned on work too
Fixa run for your iOS app no longer connects to your Mac app, or the other way round
Fixscrolling works in Mac apps, sideways too
Fixa Mac app left open no longer slows down the start of a run
FixexpectRoute on a tap no longer shows an error in your editor

Newfindings link to the line that declares the component
Newwhen a context value is recreated on every render, the finding names the context and the component that provides it
Newmemo-miss also catches props that are new objects or arrays with the same contents
Newnav-loop flags navigation loops your users don't usually take
Newsquiggle perf insights lists a session's findings, and squiggle perf watch shows them as they happen
Newperf diff --assert can fail when a finding you name appears, with failOnDetectors
Newperf diff and product analytics compare sessions from one platform at a time. Choose which with --platform

Newrage taps and dead zones are detected on every control, not only gesture-handler ones
Newcomponents wrapped in memo() or forwardRef() show up under their own names
Fixa button with no label or testID appears once in describe, not once for each component wrapping it
FixMac apps no longer report an impossible JS FPS
