• Add "db_sslkey" and "db_sslcert" options to use SSL client certificates
• Add Ubuntu 20.04 packages
• Update to Go 1.14, latest libpq
• Ensure that we set system type correctly for Heroku full snapshots
• Detect cloud providers based on hostnames from DB_URL / db_url as well
  • Previously this was only detected for the DB_HOST / db_host setting, and that is unnecessarily restrictive
  • Note that this means your instance may show up under a new ID in pganalyze after upgrading to this version
• Log Explain
  • Ignore pg_start_backup queries
  • Support EXPLAIN for queries with parameters
• Log Insights improvements
  • Experimental: Google Cloud SQL log download
  • Remove unnecessary increment of log line byte end position
  • Make stream-based log processing more robust
• Add direct "http_proxy" & similar collector settings for Proxy config
  • This avoids problems in some environments where its not clear whether
    the environment variables are set. The environment variables HTTP_PROXY,
    http_proxy, HTTPS_PROXY, https_proxy, NO_PROXY and no_proxy continue to
    function as expected.
• Fix bug in handling of state mutex in activity snapshots
  • This may have been the cause of "unlock of unlocked mutex" errors
    when having multiple servers configured.
