Release notes

Sourced from platformio's releases.

6.1.19

• Added support for Python 3.14
• Upgraded the Doctest testing framework to version 2.4.12, the GoogleTest to version 1.17.0, and the Unity to version 2.6.1, incorporating the latest features and improvements for enhanced testing capabilities
• Enhanced compatibility with the CCLS language server, improving integration with editors like Emacs, Sublime Text, and Vim ([issue #5186](platformio/platformio-core#5186))
• Improved error messages for package installation to make it easier to understand when a package is missing or incompatible ([pull #5336](platformio/platformio-core#5336)).
• Fixed a regression issue where custom build flags were not properly reflected in the compile_commands.json file, ensuring accurate compilation database generation
• Fixed an issue where fully-qualified serial port URLs (e.g., rfc2217://host:port) were incorrectly treated as wildcard patterns ([issue #5225](platformio/platformio-core#5225))

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
