+<keyword>( #<issue>|<commit>(, (#<issue>|<commit>))*)?: ([<component>])? <details>
 ```
-Keywords are:
-* Add, Feature: Adding new stuff. Difference between "Feature" and "Add" is somewhat subjective. "Feature" for user-point-of-view stuff, "Add" for other.
-* Change: Changing behaviour from user-point-of-view.
-* Remove: Removing something from user-point-of-view.
-* Codechange, Cleanup: Changes without intentional change of behaviour from user-point-of-view. Difference between "Codechange" and "Cleanup" is somewhat subjective.
-* Fix, Revert: Fixing stuff.
-* Doc, Update: Documentation changes, version increments, translator commits.
-* Prepare: Preparation for bigger changes. Rarely used.
 
-If you commit a fix for an [issue](https://github.com/OpenTTD/OpenTTD/issues), add the corresponding issue number in the form of #NNNN. Do it as well if you implement a feature with a matching entry.
+Keywords can either be player-facing, NewGRF / Script author-facing, or developer-facing.
 
-In the case of bugfixes, if you know what revision the bug was introduced (eg regression), please mention that revision as well just after the prefix. Finding the trouble-causing revision is highly encouraged as it makes backporting/branching/releases that much easier.
+For player-facing changes, we have these keywords:
+* Feature: Adding a significant new functionality to the game. This can be small in code-size, but is meant for the bigger things from a player perspective.
+* Add: Similar to Feature, but for small functionalities.
+* Change: Changing existing behaviour to an extent the player needs to know about it.
+* Fix: Fixing an issue with the game (as seen by the player).
+* Remove: Completely removing a functionality.
+* Revert: Reverting an earlier Feature / Add / Change / Fix / Remove.
+* Doc: Update to (player-facing) documentation, like in the `docs/` folder etc.
+* Update: Translator commits.
 
-To further structure the changelog, you can add sections. Example are:
-* "Network" for network specific changes
-* "NewGRF" for NewGRF additions
-* "YAPP", "NPF", for changes in these features
-* "OSX", "Debian", "win32", for OS-specific packaging changes
+For NewGRF / Script author-facing changes, we use the same keywords as player-facing changes, followed by `[NewGRF]` / `[Script]` component.
+This also means the commit is aimed (and worded) towards the NewGRF / Script authors, rather than players.
 
-Further explanations, general bitching, etc. don't go into the first line. Use a new line for those.
+For developer-facing changes, we have these keywords:
+* Codechange: Changes to the code the player is not going to notice. Refactors, modernization, etc.
+* Cleanup: Similar to Codechange, but when it is more about removing old code, rather than an actual change.
+* Codefix: Fixing problems in earlier commits that the player is not actually going to notice. Wrong comments, missing files, CI changes.
+
+If you commit a `Fix` for an [issue](https://github.com/OpenTTD/OpenTTD/issues), add the corresponding issue number in the form of #NNNNN.
+
+In the case of `Fix`es, if you know the hash of the commit in which the bug was introduced (eg regression), please mention that hash (the first 7 characters) as well just after the keyword (or, if present, after the issue number).
+Finding the trouble-causing commit is highly encouraged as it makes backporting / branching / releases that much easier.
+
+Do not mention two keywords; if two apply, pick one that best represents the commit (for example, "Fix #123" is mostly always better than "Revert", even if both are true).
+
+The `<details>` part starts with a capital and does not end with a dot.
+Try to be descriptive to what the player will notice, not to what is actually being changed in the code.
+See `changelog.txt` for inspiration.
+
+To further structure the changelog, you can add components. Example are:
+* "Network" for network specific changes.
+* "NewGRF" for NewGRF additions.
+* "Script" for AI / GS additions.
+* "YAPF", "NPF", for changes in these features.
+* "MacOS", "Linux", "Windows", for OS-specific changes.
+* "CI", "CMake", for changes to the (build) infrastructure.

+
+    TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+    1. Definitions.

+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      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
+      separable from, or merely link (or bind by name) to the interfaces of,
+      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
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+    2. Grant of Copyright 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
+      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.
