2026-07 Monthly Summary: Security and reliability improvements in TLS hostname verification for IPv6 literals in nodejs/node. Implemented a regression fix that matches IPv6 hostnames against IP-Address SANs using the original hostname, preventing false negatives in certificate verification. Added regression tests to ensure IPv6 address matching remains correct. The change preserves the DNS-name path and non-ASCII handling, reinforcing TLS correctness across IPv6 deployments and reducing user-facing certificate errors.

June 2026 LibreChat monthly summary focused on pricing accuracy and maintainability for open-weight models in the danny-avila/LibreChat repo. Implemented token-based pricing for open-weight models (devstral, mistral-medium, voxtral, holo2) to support accurate balance and transaction accounting on custom OpenAI-compatible endpoints. For models not present in tokenValues, pricing now falls back to a default rate of $6 per 1M tokens. Added explicit per-1M-token USD rates (devstral 0.4/2.0; mistral-medium 1.5/7.5; voxtral-small 0.1/0.4; holo2 0.3/0.7) and leveraged the existing longest-substring ID mapping to align versioned IDs with pricing keys. Completed pricing cleanup by removing the redundant voxtral-small key to reduce duplication and improve maintainability, following a review note for #13863 and #13867.
