    October 2026

    Latest
    • ImprovedUpdated the AI Judge model to gpt-6-luna for more accurate and context-aware feedback in workshops.

  2. v1.6.0

    September 2026

    • ImprovedA major visual refresh across the app, based on Fluid Functionalism design and principles.
    • ImprovedMenus, lists, the file tree and the nav share one highlight that slides to whatever is nearest your cursor, so you can see where a click will land before you make it
    • ImprovedHovers, menus and dialogs animate on one shorter timing, so moving around the app feels quicker
    • FixedKeyboard focus is visible again. Tabbing through buttons, dialogs and forms shows an outline that a global stylesheet had been erasing
  3. v1.5.0

    September 2026

    • NewSupport for recording and playing back network requests and responses in codealongs
    • NewYour Go code is type-checked as you type. Undefined variables, wrong argument types and typos get underlined in the editor before you ever hit Run, using the real Go type checker running locally in your browser
    • NewFormat your file with Cmd/Ctrl + S, Shift+Alt+F, or from the Run menu. Indentation is fixed and imports are sorted and added for you, in a single undo step
    • NewAdded support for external packages importing for future courses.
  4. v1.4.0

    August 2026

    • NewCommand-click any Go standard library function to jump straight into its real source. fmt.Println opens print.go read-only in a tab beside your code, with the cursor already on the definition
    • NewIn workshops the same click shows the definition inline, so you never lose your place in the step
    • ImprovedAutocomplete and hover now cover 34 standard library packages and 2,114 symbols, including reflect, net/url and net/http/httptest
    • ImprovedEditor tooling starts faster. Completions, hover and go-to-definition share one background worker now instead of each loading the same index
  5. v1.3.0

    August 2026

    • NewBuild and test real HTTP APIs in the browser. Go servers now run on a real in-process network stack, so net/http code behaves the way it does on your machine, including servers listening on more than one port
    • NewThe API panel renders JSON responses properly now, with syntax highlighting and collapsible bodies instead of a wall of text
    • ImprovedClick into the code to start tinkering whether the lesson is playing or paused. Pausing and clicking used to do nothing until you typed a character
    • ImprovedSend a request from the API panel mid-lesson and it picks up the instructor's setup, then hands you the controls in sandbox mode
  6. v1.2.0

    July 2026

    • NewCertificates of completion. Finish a course, claim a certificate with your XP, challenges solved and modules completed on it, then print it or share it to LinkedIn. Every certificate has a public link anyone can open to verify it, and they all live on your profile
    • ImprovedCourse syllabus redesigned around a lesson timeline, so you can see exactly where you are in the track and what comes next
    • ImprovedBetter course cards. Whiteboard and live SQL previews, coming soon courses, and a green finished state once you complete one
    • ImprovedWorkshops give the editor the full width when there's only one file, with tighter step instructions
  7. v1.1.1

    July 2026

    • NewCareer paths — curated, multi-course tracks (starting with Backend Engineer) that guide you through courses in order on the home page
    • NewCourse cards now show a WIP tag with a dashed border when a course is still being built, so it's clear what's ready to dig into
    • ImprovedFaster compiles. Running your code now returns as soon as the build finishes, instead of waiting on the result to finish uploading first
  8. v1.1.0

    July 2026

    • NewNew landing page with a real, playable lesson in the hero. Watch and scrub an actual Codealong lesson before you ever sign up.
    • NewPair-programming walkthrough, a "Codealong stack" section, a live whiteboard demo, and an FAQ on the landing page
    • NewLive code previews on course cards, so you can see what you'll be building at a glance
