Status update 2026-05

This article details technical updates to the pimsync synchronization tool, including the addition of digest authentication for CalDAV/CardDAV, which requires a pre-flight request for each call due to concurrency issues with nonce counters. The author also rewrote configuration parsing to reject unknown directives, resulting in cleaner, more robust code despite doubling line count. Internal improvements to libdav libraries and bug fixes are noted, with plans to upstream digest auth logic to hyper-util. The content is focused on software development, HTTP authentication, and Rust library design.
