    🐛 BUG FIXES

    • 🚀 ARM release binaries: Starting with v1.6.2, Consul will ship three separate versions of ARM builds. The previous ARM binaries of Consul could potentially crash due to the way the Go runtime manages internal pointers to its Go routine management constructs and how it keeps track of them especially during signal handling. From v1.6.2 forward, it is recommended to use:
      • consul_{version}_linux_armelv5.zip for all 32-bit armel systems
      • consul_{version}_linux_armhfv6.zip for all armhf systems with v6+ architecture
      • consul_{version}_linux_arm64.zip for all v8 64-bit architectures
    • 📜 agent: Parse the HTTP Authorization header as case-insensitive. [GH-6568]
    • agent: minimum quorum check added to Autopilot with minQuorum option [GH-6654]
    • agent: cache notifications work after error if the underlying RPC returns index=1 [GH-6547]
    • agent: tolerate more failure scenarios during service registration with central config enabled [GH-6472]
    • 🚚 cache: remove data race in agent cache [GH-6470]
    • connect: connect CA Roots in secondary datacenters should use a SigningKeyID derived from their local intermediate [GH-6513]
    • connect: don't colon-hex-encode the AuthorityKeyId and SubjectKeyId fields in connect certs [GH-6492]
    • connect: intermediate CA certs generated with the vault provider lack URI SANs [GH-6491]
    • 🔀 debug: Fix a bug in sync.WaitGroup usage. [GH-6649]
    • xds: tcp services using the discovery chain should not assume RDS during LDS [GH-6623]
