According to TechFlow, the Bitcoin developer mailing list has moved from the original hosting Sourceforge.net to the Linux Foundation, then to OSUOSL, and now it is moving to Google Groups. Bitcoin developer Brian Bishop said that this move is aimed at improving the accessibility and backup capabilities of the mailing list. Now users can view archived mails online without a Google account, and the mailing list is also backed up externally. The administrator of the mailing list encourages existing subscribers to take action as soon as possible. From February 2024, the old mailing list will no longer accept mail.
