• Stop supporting Amazon Linux 2, RHEL 7, Debian 11 (Bullseye) and Ubuntu 20.04 (Focal)
  • These distributions are end of life
  • This raises the minimum glibc requirement to 2.28 (RHEL-based) and 2.34
    (Debian-based), which is now checked explicitly during the package build
• Allow disabling WebSocket use via config setting
  • By default the collector uploads snapshots over a WebSocket connection and
    falls back to HTTP when that fails. The new setting
    api_disable_websocket / API_DISABLE_WEBSOCKET skips the WebSocket
    entirely and goes straight to HTTP, as an interim workaround for
    environments where the WebSocket connection can't be used at all
• WebSocket: Add 30 second timeout for opening connections
  • This matches how HTTP connections are handled
• WebSocket: Avoid full snapshots and test runs stalling when the endpoint is
  unreachable
  • These now wait at most 10 seconds for the WebSocket connection before
    falling back to HTTP, instead of up to a minute, while reconnects keep
    being attempted in the background
• Support PGA_API_SYSTEM_ID_FALLBACK and PGA_API_SYSTEM_TYPE_FALLBACK
  environment variables, matching the existing config file settings
