 # Change Log

+## v0.37.0
+
+Released on 2024-01-30
+
+### Breaking Changes
+
+- The deprecated `rate-limiter` mechanism is removed as it is no longer used.
+  - the deprecated `outputs.rate` Falco config is removed.
+  - the deprecated `outputs.max_burst` Falco config is removed.
+- The deprecated `--userspace` CLI option is removed as it is no longer used.
+- The `falco-driver-loader` script will be removed and embedded into falcoctl. The new falcoctl driven implementation will drop:
+  - `--source-only` CLI option.
+  - `BPF_USE_LOCAL_KERNEL_SOURCES` environment variable.
+  - `DRIVER_CURL_OPTIONS` environment variable.
+  - `FALCO_BPF_PROBE` environment variable is not used by the new falcoctl driver loader, since it is already deprecated and will be removed in the next major version.
+  
+  Some env vars were renamed:
+  - `DRIVERS_REPO` env variable has been replaced by `FALCOCTL_DRIVER_NAME`  or `--name` command line argument for `falcoctl driver` command
+  - `DRIVERS_NAME` env variable has been replaced by `FALCOCTL_DRIVER_REPOS`, or `--repo` command line argument for `falcoctl driver` command
+  - `DRIVER_KERNEL_RELEASE` env variable has been replaced by `--kernelrelease` command line argument for `falcoctl driver install` command
+  - `DRIVER_KERNEL_VERSION` env variable has been replaced by `--kernelversion` command line argument for `falcoctl driver install` command
+  - `DRIVER_INSECURE_DOWNLOAD` env variable has been replaced by `--http-insecure` command line argument for `falcoctl driver install` command
+- Remove `-K/-k` options from Falco in favor of the new `k8smeta` plugin.
+- Drop plugins shipped with Falco since plugins are now be managed by falcoctl.
+- Falco 0.37.0 allows environment variables to be expanded even if they are part of a string. This introduces small breaking changes:
+  - Previously, environment variables used in YAML that were empty or defined as `“”` would be expanded to the default value. This was not consistent with the way YAML was handled in other cases, where we only returned the default values if the node was not defined. Now expanded env vars retain the same behavior of all other variables.
+  - Falco 0.37.0 will return default value for nodes that cannot be parsed to chosen type.
+  - `program_output` command will be env-expanded at init time, instead of letting `popen` and thus the `sh` shell expand it. This is technically a breaking change even if no behavioral change is expected. Also, you can avoid env var expansion by using `${{FOO}}` instead of `${FOO}`. It will resolve to `${FOO}` and won't be resolved to the env var value.
+
