   - Launch command with custom options declared in `"platformio.ini" <https://docs.platformio.org/page/projectconf.html>`__
   - Python callback as a target (use the power of Python interpreter and PlatformIO Build API)
 
-* Display system-wide information using `platformio system info <https://docs.platformio.org/page/core/userguide/system/cmd_info.html>`__ command (`issue #3521 <https://github.com/platformio/platformio-core/issues/3521>`_)

 * List available project targets (including dev-platform specific and custom targets) with a new `platformio run --list-targets <https://docs.platformio.org/page/core/userguide/cmd_run.html#cmdoption-platformio-run-list-targets>`__ command (`issue #3544 <https://github.com/platformio/platformio-core/issues/3544>`_)
 * Added support for "globstar/`**`" (recursive) pattern for the different commands and configuration options (`platformio ci <https://docs.platformio.org/page/core/userguide/cmd_ci.html>`__, `src_filter <https://docs.platformio.org/page/projectconf/section_env_build.html#src-filter>`__, `check_patterns <https://docs.platformio.org/page/projectconf/section_env_check.html#check-patterns>`__, `library.json > srcFilter <https://docs.platformio.org/page/librarymanager/config.html#srcfilter>`__). Python 3.5+ is required.
 * Added a new ``-e, --environment`` option to `platformio project init <https://docs.platformio.org/page/core/userguide/project/cmd_init.html#cmdoption-platformio-project-init-e>`__ command that helps to update a PlatformIO project using existing environment
+* Dump data intended for IDE extensions/plugins using a new `platformio project idedata <https://docs.platformio.org/page/core/userguide/project/cmd_idedata.html>`__ command
 * Do not generate ".travis.yml" for a new project, let the user have a choice
 * Fixed an issue with PIO Unit Testing when running multiple environments (`issue #3523 <https://github.com/platformio/platformio-core/issues/3523>`_)
 * Fixed an issue with improper processing of source files added via multiple Build Middlewares (`issue #3531 <https://github.com/platformio/platformio-core/issues/3531>`_)
