 * Added the ability to show a detailed library dependency tree only in `verbose mode <https://docs.platformio.org/en/latest/core/userguide/cmd_run.html#cmdoption-pio-run-v>`__, which can help you understand the relationship between libraries and troubleshoot issues more effectively (`issue #4517 <https://github.com/platformio/platformio-core/issues/4517>`_)
 * Added the ability to run only the `device monitor <https://docs.platformio.org/en/latest/core/userguide/device/cmd_monitor.html>`__ when using the `pio run -t monitor <https://docs.platformio.org/en/latest/core/userguide/cmd_run.html>`__ command, saving you time and resources by skipping the build process
 * Added validation for `project working environment names <https://docs.platformio.org/en/latest/projectconf/sections/env/index.html#working-env-name>`__ to ensure that they only contain lowercase letters ``a-z``, numbers ``0-9``, and special characters ``_`` (underscore) and ``-`` (hyphen)
+* Upgraded the build engine to the latest version of SCons (4.5.2) to improve build performance, reliability, and compatibility with other tools and systems (`release notes <https://github.com/SCons/scons/releases/tag/4.5.2>`__)
 * Implemented a fix for shell injection vulnerabilities when converting INO files to CPP, ensuring your code is safe and secure (`issue #4532 <https://github.com/platformio/platformio-core/issues/4532>`_)
 * Restored the project generator for the `NetBeans IDE <https://docs.platformio.org/en/latest/integration/ide/netbeans.html>`__, providing you with more flexibility and options for your development workflow
 * Resolved an issue where the `build_cache_dir <https://docs.platformio.org/en/latest/projectconf/sections/platformio/options/directory/build_cache_dir.html>`__ setting was not being recognized consistently across multiple environments (`issue #4574 <https://github.com/platformio/platformio-core/issues/4574>`_)
