Node.js v26.5.0 has been released, introducing features such as streaming UTF-8 support for Blobs, experimental text file imports, and improved reporting for negotiated TLS groups, including quantum-resistant options. The release focuses on performance enhancements, particularly around TextEncoder.encode and WHATWG streams, while announcing the winding down of macOS x64 tier 2 support. The new experimental import flag for .txt files aims to align with browser compatibility and npm package stabilization, reflecting a cautious approach to development. Additionally, the performance cycle targets memory and startup efficiency, with backward compatibility maintained across all new features

Node.js v26.5.0 Released With Experimental Text Imports and Blob Streaming

Node.js v26.5.0 landed today, bringing streaming UTF-8 support for Blobs, experimental text file imports, and direct reporting of negotiated TLS groups including quantum-resistant variants. The release also tightens performance around TextEncoder.encode and WHATWG streams while quietly announcing that macOS x64 tier 2 support is winding down. Geoffrey Booth pushed to keep the new import flag experimental until browser compatibility and npm packages stabilize, matching the cautious TC39 precedent. All five minor additions remain backward compatible, though you should plan your migration before the Current stream wraps up around January 2027.
