Node.js 26 Released: Last Version Under Old Schedule Before Major Restructure

·16 views

Node.js 26 launched on May 5, 2025, and is scheduled to enter Long-Term Support on October 28, 2025, marking a significant shift in the project's release model. Starting with Node 27, the project will move from two major releases per year to one, with every release designated as LTS, eliminating the old odd/even production distinction. The upgrade introduces relatively few breaking changes, including the removal of long-deprecated internal _stream_* modules and stricter header validation via an updated Undici fetch implementation. Teams migrating from Node 24 will find the transition straightforward, while those on Node 22 face a broader set of changes and a real deadline as Node 22 exits maintenance in April 2027. Library maintainers should note a new six-month alpha channel beginning with Node 27, giving developers advance notice of breaking changes before each annual release.

Memorilla Proposes Latent Semantic Memory to Help LLMs Retain Context

A new arXiv paper introduces Memorilla, a system that proposes latent semantic memory for large language models. The approach aims to give LLMs a way to store and retrieve information within their latent representations. The source material is limited to a link and a Hacker News discussion thread with few comments, so detailed technical results are not available here.

Study finds many Lovable-built apps expose Supabase data on first page load

Researchers at Crissy Field examined 159,041 Lovable projects, of which 34,545 used Supabase. Of 24,664 sites examined more closely, many were already serving database records to visitors without any login. Further read-only requests with the public key surfaced email addresses in thousands of sites, along with more sensitive items such as passport details and chat messages. The authors caution that data appearing on first load is not automatically a confirmed leak, and the roughly 30% figure applies only to the sampled sites, not all Lovable apps. Security advisers stress that anon keys are meant to be public, so the real risk lies in missing or permissive row-level security rules.
