     - Generally speaking, we do not accept code for specific sensors. We have to be able to test the sensor in hardware on the WPILib test bed. Additionally, hardware availability for teams is important. Therefore, as a general rule, the library only directly supports hardware that is in the Kit of Parts. If you are a company interested in getting a sensor into the Kit of Parts, please contact FIRST directly at frcparts@firstinspires.org.
 
+## Contribution Process
+
+Have an idea to make WPILib better? Here's some steps to go from idea to implementation:
+
+1. (Optional) **Discuss it in the Discord.** The programming discussion channel in the [Unofficial FIRST Robotics Competition Discord Server](https://discord.com/invite/frc) is a popular choice for initial discussion about ideas because many WPILib developers are active there and the live messaging nature of the platform is well suited for initial discussion (particularly for smaller changes). Note that the unofficial Discord server is not a mandatory step in the development process and is not endorsed by FIRST®.
+2. (Recommended) **Open a GitHub issue.** GitHub issues are another way to get initial feedback about an idea before working on an implementation. Compared to the unofficial Discord server, GitHub issues have much wider visibility and are better suited for serious discussions about major changes. Getting feedback about an idea (whether in the unofficial Discord server or in a GitHub issue) before working on the implementation is recommended to avoid working on a change that will be rejected, though some ideas are pretty safe.
+3. (Rare) **Create a design document in GitHub.** Sometimes, a change is so large that a design document is necessary to fully flesh out the details (and get feedback on them) before starting on an implementation. This is done through a pull request that adds the design document (as a Markdown file) to the repository. This is extremely rare, and it is sometimes done concurrently with the implementation if the change doesn't need much debate but is large enough to require a design document.
+4. (Mandatory) **Create a GitHub pull request.** This is how you implement the changes, and is the focus of most of the rest of this document.
+
 ## Coding Guidelines
 
 WPILib uses modified Google style guides for both C++ and Java, which can be found in the [styleguide repository](https://github.com/wpilibsuite/styleguide). Autoformatters are available for many popular editors at https://github.com/google/styleguide. Running wpiformat is required for all contributions and is enforced by our continuous integration system.
 While the library should be fully formatted according to the styles, additional elements of the style guide were not followed when the library was initially created. All new code should follow the guidelines. If you are looking for some easy ramp-up tasks, finding areas that don't follow the style guide and fixing them is very welcome.
 
-### Math documentation
-
-When writing math expressions in documentation, use https://www.unicodeit.net/ to convert LaTeX to a Unicode equivalent that's easier to read. Not all expressions will translate (e.g., superscripts of superscripts) so focus on making it readable by someone who isn't familiar with LaTeX. If content on multiple lines needs to be aligned in Doxygen/Javadoc comments (e.g., integration/summation limits, matrices packed with square brackets and superscripts for them), put them in @verbatim/@endverbatim blocks in Doxygen or `<pre>` tags in Javadoc so they render with monospace font.
-
-The LaTeX to Unicode conversions can also be done locally via the unicodeit Python package. To install it, execute:
-```bash
-pip install --user unicodeit
-```
-
-Here's example usage:
-```bash
-$ python -m unicodeit.cli 'x_{k+1} = Ax_k + Bu_k'
-xₖ₊₁ = Axₖ + Buₖ
-```
-
-On Linux, this process can be streamlined further by adding the following Bash function to your .bashrc (requires `wl-clipboard` on Wayland or `xclip` on X11):
-```bash
-# Converts LaTeX to Unicode, prints the result, and copies it to the clipboard
-uc() {
-  if [ $WAYLAND_DISPLAY ]; then
-    python -m unicodeit.cli $@ | tee >(wl-copy -n)
-  else
-    python -m unicodeit.cli $@ | tee >(xclip -sel)
-  fi
-}
-```
-
-Here's example usage:
-```bash
-$ uc 'x_{k+1} = Ax_k + Bu_k'
-xₖ₊₁ = Axₖ + Buₖ
-```
-
 ## Submitting Changes
 
 ### Pull Request Format
 
 Changes should be submitted as a Pull Request against the main branch of WPILib. For most changes, commits will be squashed upon merge. For particularly large changes, multiple commits are ok, but assume one commit unless asked otherwise. We may ask you to break a PR into multiple standalone PRs or commits for rebase within one PR to separate unrelated changes. No change will be merged unless it is up to date with the current main branch. We do this to make sure that the git history isn't too cluttered.
 
-During the build season, breaking changes or other changes intended for the next season can be created as a pull request against the development branch of WPILib. After the season is over, the changes in the development branch will be merged into main.
+Particularly large and/or breaking changes should be targeted to the 2027 branch, which targets the [SystemCore Robot Controller](https://community.firstinspires.org/introducing-the-future-mobile-robot-controller). The intent is minimize changes for 2026, to allow development to focus on preparing for 2027.

+# Maintaining Generated Files
+WPILib extensively uses [metaprogramming](https://en.wikipedia.org/wiki/Metaprogramming#Code_generation) to generate code that would otherwise be tedious and error-prone to maintain. We use [Jinja](https://jinja.palletsprojects.com), a templating engine with a Python API, alongside JSON files that contain data to generate code. This document explains how to maintain these generated files and create new ones.
+
+## File hierarchy
+The Python script used to generate a subproject's files will always be located in the subproject's directory, e.g. wpilibc. It will always be called `generate_<thing>.py` where `<thing>` is the name for what you're generating.
+
+The templates will be located under `subproject/src/generate/main`, and generated files will be located under `subproject/src/generated/main`.
+
+If the generated file is for C++, the hierarchy should be symmetrical, so if a generated header is located under `subproject/src/generated/main/native/include/frc/header.h`, the template to generate it should be located under `subproject/src/generate/main/native/include/frc/template.h.jinja`. You should pretend like `subproject/src/generate/main` is just like `subproject/src/main`, in that the file hierarchy must make sense if the files weren't generated, e.g, headers that would go in `subproject/src/main/native/include/blah` should be in `subproject/src/generated/main/native/include/blah`.
+
+If the generated file is for Java, templates should be located under `subproject/src/generate/main/java`, and the hierarchy for output files should reflect the declared package of the output Java files. For example, a Jinja template at `subproject/src/main/java/template.java.jinja` with the package `edu.wpi.first.wpilibj` would be used to generate Java files located at `subproject/src/generated/main/java/edu/wpi/first/wpilibj`
+
+The JSON files live under `subproject/src/generate` since they apply to both languages. One unique case is JSON files that are used by multiple subprojects, currently only JSON files shared by wpilibc and wpilibj. In that specific case, the JSON files will always be located in wpilibj since Java is the most used language.
+
+## Using code generation
+If you've identified a set of files which are extremely similar, one file with lots of repetitive code, or both, you can create Jinja templates, a JSON file, and a Python script to automatically generate the code instead.
+
+### Preparing files for codegen
+Once you've identified the files you want to codegen, you will need to identify parts of code that are similar, and extract the data that's different. Code needs to go into your Jinja template, while data that will be used to fill in the template goes into a JSON file. Using game controllers as an example, they have lots of similar methods to read the value of a button, check if a button has been pressed since the last check, and check if a button has been released since the last check. Those methods are code that goes in a Jinja template, with the specific button replaced with a Jinja expression. The buttons, both the name and value, go into a JSON file.
+
+### Writing a Python script
+To maintain consistency with other Python scripts, copy an existing `generate_*.py` script. [generate_pwm_motor_controllers.py](./wpilibj/generate_pwm_motor_controllers.py) is a good start, since it's relatively basic. Modify the script to reference your templates and JSON file, modify the paths so the files end up in the right place, and rename the functions so they match what you're generating. An important part of the script is to give the files the correct name. Depending on files you're generating, this could be the name of the template itself (see [ntcore/generate_topics.py](./ntcore/generate_topics.py)) or it could be part of the data in the JSON file.
+
+### (Re)Generating files and committing them
+Once your Python script is complete, you can run `python generate_<thing>.py` to generate the files. Once you're finished with your files, commit these files to Git. If you regenerated the files and Git indicates the files have changed, but the diff doesn't show any changes, only the line endings have changed. If you expected changes to the generated code, you didn't correctly make changes. If you didn't expect changes, you can ignore this and discard the changes. Also ensure that you've marked the Python script as executable, since this is necessary for CI workflows to run your scripts. To add your script to the CI workflows, edit [.github/workflows/pregen_all.py](.github/workflows/pregen_all.py), and add your script alongside the rest of the scripts.

 ## Artifact classifiers
 We provide two base types of artifacts.
 
-The first types are Java artifacts. These are usually published as `jar` files. Usually, the actual jar file is published with no classifier. The sources are published with the `-sources` classifier, and the javadocs are published with the `-javadoc` classifier.
-
-The second types are native artifacts. These are usually published as `zip` files (except for the `JNI` artifact types, which are `jar` files. See below for information on this). The `-sources` and `-headers` classifiers contain the sources and headers respectively for the library. Each artifact also contains a classifier for each platform we publish. This platform is in the format `{os}{arch}`. The platform artifact only contains the binaries for a specific platform. In addition, we provide a `-all` classifier. This classifier combines all of the platform artifacts into a single artifact. This is useful for tools that cannot determine what version to use during builds. However, we recommend using the platform specific classifier when possible. Note that the binary artifacts never contain the headers, you always need the `-headers` classifier to get those.
-
-## Artifact Names
-
-WPILib builds four different types of artifacts.
-
-##### C++ Only Libraries
-When we publish C++ only libraries, they are published with the base artifact name as their artifact name, with a `-cpp` extension. All dependencies for the library are linked as shared libraries to the binary.
-
-
-Example:
-```
-edu.wpi.first.wpilibc:wpilibc-cpp:version:classifier@zip
-```
-
-#### Java Only Libraries
-When we publish Java only libraries, they are published with the base artifact name as their artifact name, with a `-java` extension.
+The first types are Java artifacts. These are usually published as `jar` files. Usually, the actual jar file is published with no classifier. The sources are published with the `-sources` classifier, and the javadocs are published with the `-javadoc` classifier. These artifacts are published with the base artifact name as their artifact ID, with a `-java` extension.
 
 Example:
 ```
 edu.wpi.first.wpilibj:wpilibj-java:version
 ```
 
-#### C++/Java Libraries without JNI
-For libraries that are both C++ and Java, but without a JNI component, the C++ component is published with the `basename-cpp` artifact name, and the Java component is published with the `basename-java` artifact name.
+The second types are native artifacts. These are usually published as `zip` files. The `-sources` and `-headers` classifiers contain the sources and headers respectively for the library. Each artifact also contains a classifier for each platform we publish. This platform is in the format `{os}{arch}`. The full list of supported platforms can be found in [native-utils](https://github.com/wpilibsuite/native-utils/blob/main/src/main/java/edu/wpi/first/nativeutils/WPINativeUtilsExtension.java#L94). If the library is built statically, it will have `static` appended to the classifier. Additionally, if the library was built in debug mode, `debug` will be appended to the classifier. The platform artifact only contains the binaries for a specific platform. Note that the binary artifacts never contain the headers, you always need the `-headers` classifier to get those.
+
+If the library is Java and C++ and has a JNI component, the native artifact will have a shared library containing JNI entrypoints alongside the C++ shared library. This JNI shared library will have a `jni` suffix in the file name.
+
+Native artifacts are published with the base artifact name as their artifact ID, with a `-cpp` extension.
 
 Example:
 ```
-edu.wpi.first.wpiutil:wpiutil-cpp:version:classifier@zip (C++)
-edu.wpi.first.wpiutil:wpiutil-java:version (Java)
-```
-
-#### C++/Java Libraries with JNI
-For libraries that are both C++ and Java with a JNI component there are three different artifact names. For Java, the component is published as `basename-java`. For C++, the `basename-cpp` artifact contains the C++ artifacts with all dependencies linked as shared libraries to the binary. These binaries DO contain the JNI entry points. The `basename-jni` artifact contains identical C++ binaries to the `-cpp` artifact, however all of its dependencies are statically linked, and only the JNI and C entry points are exported.
-
-The `-jni` artifact should only be used in cases where you want to create a self contained Java application where the native artifacts are embedded in the jar. Note in an extraction scenario, extending off of the library is never supported, which is why the C++ entry points are not exposed. The name of the library is randomly generated during extraction. For pretty much all cases, and if you ever want to extend from a native library, you should use the `-cpp` artifacts. GradleRIO uses the `-cpp` artifacts for all platforms, even desktop, for this reason.
-
-Example:
-```
-edu.wpi.first.ntcore:ntcore-cpp:version:classifier@zip (C++)
-edu.wpi.first.ntcore:ntcore-jni:version:classifier (JNI jar library)
-edu.wpi.first.ntcore:ntcore-java:version (Java)

+# WPILib Bazel Support
+
+WPILib is normally built with Gradle, but [Bazel](https://www.bazel.build/) can also be used to increase development speed due to the superior caching ability and the ability to use remote caching and remote execution (on select platforms)
+
+
+## Prerequisites
+- Install [Bazelisk](https://github.com/bazelbuild/bazelisk/releases) and add it to your path. Bazelisk is a wrapper that will download the correct version of bazel specified in the repository. Note: You can alias/rename the binary to `bazel` if you want to keep the familiar `bazel build` vs `bazelisk build` syntax.
+
+## Building
+To build the entire repository, simply run `bazel build //...`. To run all of the unit tests, run `bazel test //...`
+Other examples:
+- `bazel build //wpimath/...` - Builds every target in the wpimath folder
+- `bazel test //wpiutil:wpiutil-cpp-test` - Runs only the cpp test target in the wpiutil folder
+- `bazel coverage //wpiutil/...` - (*Nix only) - Runs a code coverage report for both C++ and Java on all the targets under wpiutil
+
+## User settings
+When invoking bazel, it will check if `user.bazelrc` exists for additional, user specified flags. You can use these settings to do things like always ignore buildin a specific folder, or limiting the CPU/RAM usage during a build.
+Examples:
+- `build --build_tag_filters=-wpi-example` - Do not build any targets tagged with `wpi-example` (Currently all of the targets in wpilibcExamples and wpilibjExamples contain this tag)
+- `build -c opt` - Always build optimized targets. The default compiler flags were chosen to build as fast as possible, and thus don't contain many optimizations
+- `build -k` - `-k` is analogous to the MAKE flag `--keep-going`, so the build will not stop on the first error.
+- ```
+  build --local_ram_resources=HOST_RAM*.5 # Don't use more than half my RAM when building
+  build --local_cpu_resources=HOST_CPUS-1 # Leave one core alone
+  ```

+      "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

+      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.

+# Benchmark
+
+This is a benchmark project built directly against this repo's sources.
+
+## Desktop benchmarking
+
+This command runs the Java benchmarks on desktop.
+
+```bash
+./gradlew benchmark:run
+```
+
+This command runs the C++ benchmarks on desktop.
+
+```
+./gradlew benchmark:runCpp
+```
+
+## Deploy to a roboRIO
+
+This project can only deploy over USB. If an alternate IP address is preferred, the `address` block in benchmark/build.gradle can be changed to point to another address.
+
+This command deploys the C++ project using shared dependencies. Prefer this one for most C++ development.
+```bash
+./gradlew benchmark:deployShared
+```
+
+This command deploys the C++ project with all dependencies statically linked.
+```bash
+./gradlew benchmark:deployStatic
+```
+
+This command deploys the Java project and all required dependencies. It also installs the JRE if it's not currently installed.
+```bash
+./gradlew benchmark:deployJava
+```
+
+Those commands won't start the robot executable, so you have to manually ssh in and start it. The following command will do that.
+```bash
+ssh lvuser@172.22.11.2 frcRunRobot.sh
+```
+
+Console log prints will appear in the terminal.
+
+Deploying any of these to the roboRIO will disable the current startup project until it is redeployed.
+
+## Faster builds
+
+If your benchmarks only need some projects, you can comment out or delete unnecessary subprojects from the dependencies, benchmarkCpp, and benchmarkCppStatic blocks in benchmark/build.gradle (Java or C++) and from `target_link_libraries()` in benchmark/CMakeLists.txt (C++ only).

+// If you need the above guarantees, please consider using a different

+// granularity and implemented as a memory read. A memory read is generally
+// cheaper than the CycleClock for many architectures.
+//
+// Also, in some out of order CPU implementations, the CycleClock is not
+// serializing. So if you're trying to count at cycles granularity, your
