June 2025 (Shopify/nixpkgs) focused on correctness and reliability of remoting naming for Firefox Developer Edition. Delivered a targeted fix by removing a conflicting branding definition, ensuring the correct remoting name is consistently applied across all remoting contexts. This improves application identification, reduces user confusion, and enhances telemetry accuracy. The change also aligns branding with upstream expectations and reduces future maintenance burden.
