Hi Everyone: As previously announced, we will migrate the existing mailing list to a new service provider and upgrade the mailing list software to a newer version (from Mailman 2 to Mailman 3). The migration is scheduled for: Sunday, July 19, 2026, at 6am UTC (2am EDT). We will take a snapshot of the current mailing list data on Saturday, July 18, the day before. The snapshot will be the source for the migration. To ensure no messages are lost, please don't post over the weekend (starting on Saturday) until we confirm the process is complete. We have also been working on not breaking existing links to messages in the archive. The new provider offered to host a list of redirects on their server, mapping from the old to the new URL scheme. We expect that the majority of links will be preserved this way, but this will be implemented after the migration. Thanks, Gregor
