Since October 2026 `npm install prisma` / `npx prisma` give the Prisma ORM 8 release candidate (8.0.0-rc.26 on 2026-10-22) on Node 22.18+, 24.11+ or 26+. It has no `generate`, `migrate dev` or `db push`, does not read `schema.prisma`, and queries are written differently. `@prisma/client` stays 7.10.1. Prisma 7 projects: `npm install --save-dev prisma@7`, `"prisma": "^7"` and `"@prisma/client": "^7"`, and `npx prisma@7` anywhere without a lockfile.
Node.js 26 is Active LTS from 2026-10-28 to 2027-10-20 (EOL 2029-04-30). Node 24 is in maintenance since 2026-10-20 (EOL 2028-04-30), Node 22 EOL 2027-04-30, Node 20 EOL since 2026-04-30. Node 26 removes `res.writeHeader()`, the `_stream_*` modules and `--experimental-transform-types`, deprecates `module.register()`, and enables Temporal. From Node 27 every line becomes LTS (alpha in October, Current in April, LTS the next October).
Since 2026-10-21 the current Claude API version is `2026-10-21`. `temperature`, `top_p` and `top_k` are removed (400 on every model, even at the default). `@anthropic-ai/sdk` 1.0 and `anthropic` 2.0 send the new version, drop those parameters from their types, send the key as `Authorization: Bearer`, and accept one credential per client.
