 # Change Log
 
+
+## v0.36.0
+
+Released on 2023-09-25
+
+### Breaking Changes
+
+- The default rules file that is shipped in the Falco image and/or can be downloaded via falcoctl as `falco-rules` is now a _stable_ rule file. This file **contains a much smaller number of rules** that are less noisy and have been vetted by the community. This serves as a much requested "starter" Falco rule set that covers many common use case. The rest of that file has been expanded and split into `falco-incubating-rules` and `falco-sandbox-rules`. For more information, see the [rules repository](https://github.com/falcosecurity/rules)
+- The main `falcosecurity/falco` container image and its `falco-driver-loader` counterpart have been upgraded. Now they are able to compile the kernel module or classic eBPF probe for relatively newer version of the kernel (5.x and above) while we no longer ship toolchains to compile the kernel module for older versions in the default images. Downloading of prebuilt drivers and the modern eBPF will work exactly like before. The older image, meant for compatibility with older kernels (4.x and below), is currently retained as `falcosecurity/falco-driver-loader-legacy`.
+- The Falco HTTP output no longer logs to stdout by default for performance reasons. You can set stdout logging preferences and restore the previous behavior with the configuration option `http_output.echo` in `falco.yaml`.
+- The `--list-syscall-events` command line option has been replaced by `--list-events` which prints all supported system events (syscall, tracepoints, metaevents, internal plugin events) in addition to extra information about flags.
+- The semantics of `proc.exepath` have changed. Now that field contains the executable path on disk even if the binary was launched from a symbolic link.
+- The `-d` daemonize option has been removed.
+- The `-p` option is now changed:
+    - when only `-pc` is set Falco will print `container_id=%container.id container_image=%container.image.repository container_image_tag=%container.image.tag container_name=%container.name`
+    - when `-pk` is set it will print as above, but with `k8s_ns=%k8s.ns.name k8s_pod_name=%k8s.pod.name` appended
+
+
+### Major Changes
+
+
+* new(falco-driver-loader): --source-only now prints the values as env vars [[#2353](https://github.com/falcosecurity/falco/pull/2353)] - [@steakunderscore](https://github.com/steakunderscore)
+* new(docker): allow passing options to falco-driver-loader from the driver loader container [[#2781](https://github.com/falcosecurity/falco/pull/2781)] - [@LucaGuerra](https://github.com/LucaGuerra)
+* new(docker): add experimental falco-distroless image based on Wolfi [[#2768](https://github.com/falcosecurity/falco/pull/2768)] - [@LucaGuerra](https://github.com/LucaGuerra)
+* new: the legacy falco image is available as driver-loader-legacy [[#2718](https://github.com/falcosecurity/falco/pull/2718)] - [@LucaGuerra](https://github.com/LucaGuerra)
+* new: added option to enable/disable echoing of server answer to stdout (disabled by default) when using HTTP output [[#2602](https://github.com/falcosecurity/falco/pull/2602)] - [@FedeDP](https://github.com/FedeDP)

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,

+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
