Do you remember we once told you Armeria 1.0.0 will be out around the end of 2019? It's already 50% past 2020, COVID-19 still strays around the city, and we have yet a few issues in our ever-growing backlog for the next release. Nevertheless, I feel like 1.0.0 is really close this time. Así es la vida! 😅 — @trustin

From the devs

• We now have our own domain, armeria.dev! 🌟
• Armeria 0.99.8, 0.99.7 and 0.99.6 have been released.
  • New CircuitBreakerRule and CircuitBreakerRuleWithContent API let you define a complex circuit breaking policy conveniently.
