 - [#3350](https://github.com/grafana/k6/pull/3350) In k6 [v0.37](https://github.com/grafana/k6/releases/tag/v0.37.0), we deprecated a gRPC Invoke's parameter `headers`. This release removes the parameter. If you need to set headers, use a `metadata` parameter instead.
 - [#3448](https://github.com/grafana/k6/pull/3448) metric names now need to conform to both otel and prometheus name requirements while still being limitted to 128 characters (old k6 limit).
 - [#3451](https://github.com/grafana/k6/pull/3451) In k6 [v0.25](https://github.com/grafana/k6/releases/tag/v0.25.0) module specifiers were allowed to be urls with scheme, and k6 prepending `https://` to anything that it wasn't recognizing was deprecated. From this version k6 will no longer try to do that all, please use full URLs if you want to load remote modules.
+- [#3389](https://github.com/grafana/k6/pull/3389) In k6 [v0.38](https://github.com/grafana/k6/releases/tag/v0.38.0) we deprecated `--logformat` introducing the better alternative `--log-format`. This release removes `--logformat` flag.
+- [#3390](https://github.com/grafana/k6/pull/3390) In k6 [v0.35](https://github.com/grafana/k6/releases/tag/v0.35.0) we deprecated all CSV output's CLI arguments having a not consistent case with other outputs. This release removes them.
+- [#3365](https://github.com/grafana/k6/pull/3365) In k6 [v0.41](https://github.com/grafana/k6/releases/tag/v0.41.0) we deprecated the `k6 convert` CLI command. This release deleted it, the better [har-to-k6](https://github.com/grafana/har-to-k6) alternative should be used.

 ## UX improvements and enhancements
 
 - [browser#1074](https://github.com/grafana/xk6-browser/pull/1074) Adds a new `browser.closeContext()` [method](https://k6.io/docs/javascript-api/k6-experimental/browser/closecontext/) to facilitate closing the current active browser context.
-- [#3370](https://github.com/grafana/k6/pull/3370). The k6 got a new flag `--profiling-enabled` which enables exposing [pprof](https://go.dev/blog/pprof) profiling endpoints. The profiling endpoints are exposed on the same port as the HTTP REST API under the `/debug/pprof/` path. This could be useful for the extension developers.
-- [#3442](https://github.com/grafana/k6/pull/3442). The k6 now supports a new `--version` flag. It has the same output as `k6 version` command. Thanks, @ffapitalle!
-- [#3423](https://github.com/grafana/k6/pull/3423). The InfluxDB output got an environment variable `K6_INFLUXDB_PROXY` which allows specifying proxy. Thanks, @IvanovOleg!
-- [#3398](https://github.com/grafana/k6/pull/3398). The k6 cloud traces are enabled by default.
