I added three plain-Vite React starters alongside the existing Next.js/SvelteKit ones, and moved the Jazz Cloud provisioning step into the create-jazz CLI itself with a --hosting flag so you can set up hosting during scaffolding.
I added a fallback so Jazz apps work in Firefox private browsing mode. When the browser blocks access to the Origin Private File System (OPFS) with a SecurityError, the app now transparently falls back to in-memory storage instead of crashing.
I added schema validation warnings to jazz-tools deploy that flag tables without explicit permission policies. The warnings are informational only and don't block the deploy, but they help catch accidental permission gaps before they reach production.
I added an interactive widget to the quickstart docs that generates an app ID, admin secret, and backend secret from the hosted Jazz Cloud service. It automatically substitutes the generated values into the code examples on the page.
I built an interactive CLI scaffolder so you can run npm create jazz to bootstrap a new project. It prompts for your framework choice and auth mode, then fetches the right starter template, resolves dependencies, and initialises git.
I added an AuthBackup component to four local-first starter templates with recovery phrase and passkey backup/restore support. This gives users a way to recover their account if they lose their device.
I added an optional feature that fixes a tricky timing problem. When a user's device clock is slightly wrong (drifting), it can cause data to be timestamped incorrectly. This feature uses the existing ping messages between the client and server to estimate how far off the clock is, and quietly corrects timestamps so they're accurate.
I updated the alphaTab music notation library to its latest version and added a Vite-based sample project. alphaTab is a library for rendering and playing guitar tablature and sheet music in the browser.
I deleted 6 test files (about 2,450 lines) from the moon-lander-react example that weren't actually exercising Jazz's sync capabilities. I kept the 4 genuine cross-client sync tests that test what the example is really about.
I added "type": "module" to the jazz-wasm package.json. Without it, running the CLI via npx or bunx would fail with an ERR_REQUIRE_CYCLE_MODULE error because Node.js was treating the ES module output as CommonJS.
I switched from dynamic runtime URL resolution to a static new URL(...) pattern for the web worker bootstrap. This lets bundlers like Vite, webpack, and Next.js/Turbopack detect and co-bundle the worker and WASM files correctly.
I built a new Vite plugin for SvelteKit projects that manages the Jazz dev-server lifecycle automatically. It supports embedded server mode, connecting to an external URL, or reading the config from environment variables.
I promoted read durability from a footnote to its own top-level section on the reading/queries page, with tier definitions, per-tier guidance, and reference material so developers can choose the right durability level for their use case.
I added changeset entries to document two bug fixes — one for a hang when loading data with mismatched schemas during migrations, and one for a race condition in Better Auth that was logging users out. Changesets are how Jazz tracks what changed between versions, so these make sure the fixes get properly noted in the changelog.
If your app's migration tried to load a piece of data whose shape didn't match any of the allowed schema variants, Jazz would silently get stuck forever instead of telling you what had gone wrong. The error was being thrown inside an internal loop that swallowed it, so the underlying promise never settled. I added a dedicated error type for this case and caught it in the right place, so loads now fail cleanly as "unavailable" rather than hanging your app.
When signing in with Better Auth, a slow /get-session request could arrive after the user had already successfully signed in via a different flow. Because the slow response said "no session", it would log the user straight back out again. I added a little counter that increments each time the user authenticates, and we attach it as a header to session requests -- if a stale response comes back with an old counter value, we now know to ignore it.
I added Rust code tabs (create, load, delete) to the files-and-blobs documentation page, matching the TypeScript/Rust tab pattern used across the rest of the docs.
I migrated the three remaining hand-rolled HashMap call sites in the examples to use the new row_input! macro, and enabled SQLite for persistent storage in the todo-server tests.
I added From<T> implementations on the Value type for common Rust types and introduced a row_input! macro for building HashMaps more ergonomically. This deleted about 250 lines of boilerplate across the codebase.
I built a multiplayer moon lander game as an example app for Jazz using React and Phaser. It demonstrates real-time multiplayer sync — multiple players can fly their landers at the same time and see each other's movements.
