-# go-zero Roadmap
-
-This document defines a high level roadmap for go-zero development and upcoming releases.
-Community and contributor involvement is vital for successfully implementing all desired items for each release.
-We hope that the items listed below will inspire further engagement from the community to keep go-zero progressing and shipping exciting and valuable features.
-
-## 2021 Q2
-- [x] Support service discovery through K8S client api
-- [x] Log full sql statements for easier sql problem solving
-
-## 2021 Q3
-- [x] Support `goctl model pg` to support PostgreSQL code generation
-- [x] Adapt builtin tracing mechanism to opentracing solutions
-
-## 2021 Q4
-- [x] Support `username/password` authentication in ETCD
-- [x] Support `SSL/TLS` in ETCD
-- [x] Support `SSL/TLS` in `zRPC`
-- [x] Support `TLS` in redis connections
-- [x] Support `goctl bug` to report bugs conveniently
-
-## 2022
-- [x] Support `context` in redis related methods for timeout and tracing
-- [x] Support `context` in sql related methods for timeout and tracing
-- [x] Support `context` in mongodb related methods for timeout and tracing
-- [x] Add `httpc.Do` with HTTP call governance, like circuit breaker etc.
-- [ ] Support `goctl doctor` command to report potential issues for given service
-- [ ] Support `goctl mock` command to start a mocking server with given `.api` file
