-
-## 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-  - `DRIVERS_REPO` env variable has been replaced by `FALCOCTL_DRIVER_NAME`  or `--name` command line argument for `falcoctl driver` command
-  - `DRIVERS_NAME` env variable has been replaced by `FALCOCTL_DRIVER_REPOS`, or `--repo` command line argument for `falcoctl driver` command
-  - `DRIVER_KERNEL_RELEASE` env variable has been replaced by `--kernelrelease` command line argument for `falcoctl driver install` command
-  - `DRIVER_KERNEL_VERSION` env variable has been replaced by `--kernelversion` command line argument for `falcoctl driver install` command
-  - `DRIVER_INSECURE_DOWNLOAD` env variable has been replaced by `--http-insecure` command line argument for `falcoctl driver install` command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.

-
-## v0.36.0
-
-Released on 2023-09-26
-
-### 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

-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      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,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      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,
-      work stoppage, computer failure or malfunction, or any and all
-      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
-      the Work or Derivative Works thereof, You may choose to offer,
-      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.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.
-
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"
-      replaced with your own identifying information. (Don't include
-      the brackets!)  The text should be enclosed in the appropriate
-      comment syntax for the file format. We also recommend that a
-      file or class name and description of purpose be included on the
-      same "printed page" as the copyright notice for easier
-      identification within third-party archives.

-#
-# Available engines:
-# - `kmod`: Kernel Module (Kernel Module)
-# - `ebpf`: eBPF (eBPF probe)

-# - `nodriver`: No driver is injected into the system.
-#   This is useful to debug and to run plugins with 'syscall' source.
-#
-# Only one engine can be specified in the `kind` key.
-# Moreover, for each engine multiple options might be available,
-# grouped under engine-specific configuration keys.
-# Some of them deserve an in-depth description:
-#
-################### `buf_size_preset`
-#
-# --- [Description]
-#
-# The syscall buffer index determines the size of the shared space between Falco
-# and its drivers. This shared space serves as a temporary storage for syscall
-# events, allowing them to be transferred from the kernel to the userspace
-# efficiently. The buffer size for each online CPU is determined by the buffer
-# index, and each CPU has its own dedicated buffer. Adjusting this index allows
-# you to control the overall size of the syscall buffers.
-#
-# --- [Usage]
-#
-# The index 0 is reserved, and each subsequent index corresponds to an
-# increasing size in bytes. For example, index 1 corresponds to a size of 1 MB,
-# index 2 corresponds to 2 MB, and so on:
-#
-# [(*), 1 MB, 2 MB, 4 MB, 8 MB, 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, 512 MB]
-#   ^    ^     ^     ^     ^     ^      ^      ^       ^       ^       ^
-#   |    |     |     |     |     |      |      |       |       |       |
-#   0    1     2     3     4     5      6      7       8       9       10
-#
-#
-# The buffer dimensions in bytes are determined by the following requirements:
-# (1) a power of 2.
-# (2) a multiple of your system_page_dimension.
-# (3) greater than `2 * (system_page_dimension).
-#
-# The buffer size constraints may limit the usability of certain indexes. Let's
-# consider an example to illustrate this:
-#
-# If your system has a page size of 1 MB, the first available buffer size would
-# be 4 MB because 2 MB is exactly equal to 2 * (system_page_size), which is not
-# sufficient as we require more than 2 * (system_page_size). In this example, it
-# is evident that if the page size is 1 MB, the first index that can be used is 3.
-#
-# However, in most cases, these constraints do not pose a limitation, and all
-# indexes from 1 to 10 can be used. You can check your system's page size using
-# the Falco `--page-size` command-line option.
-# 
-# --- [Suggestions]
-#
-# The buffer size was previously fixed at 8 MB (index 4). You now have the
-# option to adjust the size based on your needs. Increasing the size, such as to
-# 16 MB (index 5), can reduce syscall drops in heavy production systems, but may
-# impact performance. Decreasing the size can speed up the system but may
-# increase syscall drops. It's important to note that the buffer size is mapped
-# twice in the process' virtual memory, so a buffer of 8 MB will result in a 16
-# MB area in virtual memory. Use this parameter with caution and only modify it
-# if the default size is not suitable for your use case.
-#
-################### `drop_failed_exit`
-#
-# --- [Description]
-#
-# Enabling this option in Falco allows it to drop failed system call exit events
-# in the kernel drivers before pushing them onto the ring buffer. This
-# optimization can result in lower CPU usage and more efficient utilization of
-# the ring buffer, potentially reducing the number of event losses. However, it
-# is important to note that enabling this option also means sacrificing some
-# visibility into the system.
-#
-################### `cpus_for_each_buffer` (modern_ebpf only)
-#
-# --- [Description]
-#
-# The modern_bpf driver in Falco utilizes the new BPF ring buffer, which has a
-# different memory footprint compared to the current BPF driver that uses the
-# perf buffer. The Falco core maintainers have discussed the differences and
-# their implications, particularly in Kubernetes environments where limits need
-# to be carefully set to avoid interference with the Falco daemonset deployment
-# from the OOM killer. Based on guidance received from the kernel mailing list,
-# it is recommended to assign multiple CPUs to one buffer instead of allocating
-# a buffer for each CPU individually. This helps optimize resource allocation
-# and prevent potential issues related to memory usage.
-#
-# This is an index that controls how many CPUs you want to assign to a single
-# syscall buffer (ring buffer). By default, for modern_bpf every syscall buffer
-# is associated to 2 CPUs, so the mapping is 1:2. The modern BPF probe allows
-# you to choose different mappings, for example, changing the value to `1`
-# results in a 1:1 mapping and would mean one syscall buffer for each CPU (this
-# is the default for the `bpf` driver).
-#
-# --- [Usage]
-#
-# You can choose an index from 0 to MAX_NUMBER_ONLINE_CPUs to set the dimension
-# of the syscall buffers. The value 0 represents a single buffer shared among
-# all online CPUs. It serves as a flexible option when the exact number of
-# online CPUs is unknown. Here's an example to illustrate this:
-#
-# Consider a system with 7 online CPUs:
-#
-#          CPUs     0  X  2  3  X  X  6  7  8  9   (X means offline CPU)
-#
-# - `1` means a syscall buffer for each CPU so 7 buffers
-#
-#          CPUs     0  X  2  3  X  X  6  7  8  9   (X means offline CPU)
-#                   |     |  |        |  |  |  |
-#       BUFFERs     0     1  2        3  4  5  6
-#
-# - `2` (Default value) means a syscall buffer for each CPU pair, so 4 buffers
-#
-#          CPUs     0  X  2  3  X  X  6  7  8  9   (X means offline CPU)
-#                   |     |  |        |  |  |  |
-#       BUFFERs     0     0  1        1  2  2  3
-#
-# Please note that in this example, there are 4 buffers in total. Three of the
-# buffers are associated with pairs of CPUs, while the last buffer is mapped to
-# a single CPU. This arrangement is necessary because we have an odd number of
-# CPUs.
-#
-# - `0` or `MAX_NUMBER_ONLINE_CPUs` mean a syscall buffer shared between all
-#   CPUs, so 1 buffer
-#
-#          CPUs     0  X  2  3  X  X  6  7  8  9   (X means offline CPU)
-#                   |     |  |        |  |  |  |
-#       BUFFERs     0     0  0        0  0  0  0
-#
-# Moreover, you have the option to combine this parameter with
-# `buf_size_preset` index. For instance, you can create a large shared
-# syscall buffer of 512 MB (using buf_size_preset=10) that is
-# allocated among all the online CPUs.
-#
-# --- [Suggestions]
-#
-# The default choice of index 2 (one syscall buffer for each CPU pair) was made
-# because the modern bpf probe utilizes a different memory allocation strategy
-# compared to the other two drivers (bpf and kernel module). However, you have
-# the flexibility to experiment and find the optimal configuration for your
-# system.
-# 
-# When considering a fixed buf_size_preset and a fixed buffer dimension:
-# - Increasing this configs value results in lower number of buffers and you can
-#   speed up your system and reduce memory usage
-# - However, using too few buffers may increase contention in the kernel,
-#   leading to a slowdown.
-# 
-# If you have low event throughputs and minimal drops, reducing the number of
-# buffers (higher `cpus_for_each_buffer`) can lower the memory footprint.
