Starred repos weekly — Jun 9–15, 2026
VS Code 1.124 ships a rebuilt Agents window, session navigation, and Autopilot on by default — upgrade now. Tailwind v4.3.1 fixes Node 26 deprecations, @apply in mixins, and ~20 other bugs (skip if musl/Alpine). Next.js, React, and Rust all hold at their prior stable releases.

VS Code 1.124 ships this week with a rebuilt Agents window and Autopilot on by default. Tailwind v4.3.1 quietly lands 20-plus bug fixes. The other three repos hold at their prior stable releases — here's where each stands and whether you should move.
VS Code — 1.124.2 (Jun 12) ✅ Upgrade
microsoft/vscode — the source-code editor (186k ⭐)
1.124 is a focused agentic-workflow release. If you use Copilot in VS Code, this one matters.
Agents window overhaul: the companion window for working across many simultaneous Copilot sessions now restores your layout on reload (visible sessions, their order, pinned/read status), so reopening VS Code doesn't scatter your context. You can open a new background session with Alt+Enter without losing your current one, and jump between sessions with Ctrl+R (a searchable Quick Pick), Ctrl+Tab / Shift+Tab (most-recently-visited order), or Ctrl+1–9 (by grid position). 1
Autopilot is now on by default: Autopilot — the permission level that lets agents act without per-step approval — is enabled for all users. Organizations can still lock it via
chat.tools.global.autoApprove. The companion feature, Advanced Autopilot (chat.autopilot.advanced.enabled), swaps the fixed completion rules for a small utility model that reads the chat transcript and decides whether the task is actually done, then surfaces its current objective in a tooltip above the chat. It loops at most three times before stopping.Integrated browser improvements: the browser now retains a visit history, surfaced as URL-bar suggestions (
Ctrl+H to manage). Agents can type and submit text in one typeInPage tool call instead of two, halving round-trips for form automation.Patch releases 1.124.1 and 1.124.2 closed additional regressions in the same cycle. 1
Hot issues: #253136 (Meta: chat request failures) and #253137 (Language Model Unavailable) are the current tracking issues for Copilot connectivity errors — useful if agents misbehave after the Autopilot default flip.
Upgrade risk: Low. No removed APIs; the Autopilot default change is behavioral, not a breaking code change. Orgs managing Copilot access should review
chat.tools.global.autoApprove before rolling out.コンテンツカードを読み込んでいます…
Next.js — canary v16.3.0 active, stable holds ⏸ Hold
vercel/next.js — the React framework (140k ⭐)
The
latest npm tag now points to v16.2.9 (Jun 10), but that release is an empty version published solely to correct a dist-tag mistake — it contains no code changes. 2 The last real stable release remains v16.2.7.The more significant activity this week was the opening of the v16.3.0 preview channel:
v16.3.0-preview.0 through .3 landed Jun 9–10, and canary builds ran to .51 by Jun 14. Preview highlights include stabilizing export const prefetch (removes the unstable_ prefix), enabling Turbopack filesystem caching by default in non-stable releases, and renaming the force-runtime prefetch option to allow-runtime. This is a forward-looking look at what 16.3.0 stable will carry, not something to deploy to production yet. 3Hot issues: #54708 (High memory usage in development) continues to draw the most comments. #86577 (cacheComponents/Activity component breaking app logic) is the current heat-spot for anyone experimenting with the
cacheComponents experimental flag. 4Upgrade risk: N/A. No stable change. If you're on v16.2.x, stay there; v16.3.0 is not yet stable.
React — v19.2.7 (Jun 1), no new release ⏸ Hold
facebook/react — the UI library (246k ⭐)
No React releases landed in the Jun 9–15 window. The last batch — v19.2.7, v19.1.8, and v19.0.7 — shipped Jun 1 with a single fix: a missing
FormData entries regression in Server Actions introduced in the .6 patch series. If you were on any .6 release and haven't moved, those fixes are the reason to upgrade. 5Hot issues: #13991 (Hooks + multiple React instances) remains the long-running top thread. More practically relevant: #29034 (React 19 — opt out of automatic form reset on Form Actions) is active, if you're using the new form actions API and find the default reset behavior surprising. 6
Upgrade risk: N/A this week. If on 19.x.6, upgrade to .7. If already on .7, hold.

Rust — 1.96.0 (May 28), stable until ~Jul 2026 ⏸ Hold
rust-lang/rust — the Rust programming language (114k ⭐)
No new Rust release this week. 1.96.0, which shipped May 28, remains current. Key points from that release worth recapping:
assert_matches! and debug_assert_matches! are now stable; six new core::range::* types landed (including Range, RangeFrom, RangeToInclusive and their iterator variants); Cargo patched CVE-2026-5222 and CVE-2026-5223. The next stable release is expected around early July 2026. 7Hot issues: The ongoing CI experiments PR #112049 and -Znext-solver experiments #133502 top the comments list but are internal infrastructure probes marked "do not merge." More user-relevant: allocator traits tracking #32838 — the custom allocator API is still evolving if your project depends on
std::alloc. 8Upgrade risk: Low if still on 1.95.x — 1.96.0 ships several compatibility notes (enum layout changes, wasm
--allow-undefined removed, $crate self-import restriction). Review the compatibility notes before upgrading in CI.Tailwind CSS — v4.3.1 (Jun 12) ✅ Upgrade (conditional)
tailwindlabs/tailwindcss — utility-first CSS framework (95.6k ⭐)
v4.3.1 is a pure bug-fix patch over v4.3.0, landing Jun 12 with around 20 fixes. The ones most likely to affect real projects:
- Node 26: uses
Module#registerHooksinstead of the deprecatedModule#register, removing the deprecation warnings Node 26 started emitting. 9 @applywith CSS mixins now works where it was previously blocked.not-*variants correctly negate@containerqueries includingstyle(…)queries.- Rspack:
@tailwindcss/webpackcan now be installed in Rspack projects without requiringwebpackas a peer dependency. - Symlink scanning:
@sourceglobs with symlinks are now preserved; explicitly referenced@sourcedirectories are scanned even when git-ignored. - Spacing output:
m-0now emits0instead ofcalc(var(--spacing) * 0), andm-1emitsvar(--spacing)instead ofcalc(var(--spacing) * 1)— smaller, cleaner output.
Still open: #17958 —
lightningcss.linux-x64-musl.node module not found — affects Alpine Linux / Docker musl environments and is blocked on an upstream fix. If you build in musl containers, stay on v4.3.0 or pin a workaround.Hot issues: #15005 (
@property unsupported in shadow roots) and #15045 (addComponents writing to @layer utilities instead of @layer components) are the two most discussed open threads.Upgrade risk: Low for non-musl environments. Drop-in upgrade from v4.3.0.
