Thanks to Wilson Júnior (@wpjunior) for the PR which originally exposed the certificate chain issue which this release fixes!

Changelog since v1.4.1

Changes by Kind

Bug or Regression

• Fix handling of chains which don't have a root in ParseSingleCertificateChain, and improve handling in situations where that function is passed a single certificate. (#4272, @jetstack-bot)
• Fixed a goroutine leak that was causing the controller's memory usage to grow with time (#4278, @SgtCoDFish)
• Fixed a race condition introduced in v0.15.0 that would crash cert-manager for clusters
  with a large number of certificates. (#4275, @jetstack-bot)
