node:inspector and node:repl become usable ports (
7c49f0d, 1960936)
Bun now implements node:inspector coverage APIs and inspector.open() with a real DevTools-protocol server, plus a substantial node:repl port that replaces the stub with Node-compatible interactive behavior. These changes materially improve Node.js compatibility for debugging, coverage, completion, history, and bun --interactive workflows.
node:quic lands on lsquic (762cefb)
Bun adds an experimental node:quic implementation backed by lsquic, covering HTTP/3, bidirectional and unidirectional streams, datagrams, resumption, qlog/keylog, and more. This is a major new networking surface for apps that want Node QUIC/HTTP3 compatibility.
TLS shutdown, injected-socket, and handshake paths fixed (85f22bb)
This patch tightens TLS correctness across shutdown and wrapped-socket upgrade flows, including sending close_notify on end(), fixing reject-handshake wire behavior, and addressing data-loss and SNI/ALPN edge cases. It also adds vendored upstream tests and lifts TLS coverage from 81% to 86%.
Blob/File lastModified NaN boxing hardened (
b321f82)
Blob/File now purify lastModified before boxing it into a JS value, closing a structured-clone/deserialization bug where crafted NaN bit patterns could forge invalid immediates or pointers. That turns a potential crash / memory-safety issue into a normal numeric NaN.
SQLite empty aliases and row-returning behavior corrected (ae4b17d)
Bun’s sqlite bindings now preserve empty-name columns instead of dropping them, and row-returning paths are keyed off sqlite3_column_count() instead of cached column-name state. This fixes observable API mismatches with Node/better-sqlite3 for queries that include AS "" or otherwise rely on exact column counts.
CommonJS module heap snapshots now show hidden slots (
44f6469)
Heap snapshots now report module.children and module._compile as property edges on CommonJS Module objects, matching what GC already sees. This improves snapshot fidelity for debugging memory retention in module graphs.
