The latest version of our login filter had a bug which impacted POST requests after a minute of web inactivity, which had visibly affected the Pipeline, merit skimmer, and astro skimmer. I've fixed that bug.
Pipeline front end from 3.2.1 to 3.2.2.
Merit skimmer to 1.8.1 from 1.8.
Astroserver to 1.4.6 from 1.4.5.
