For this first release of Chrome in 2023, there is a lot in store on the feature side. Among the changes to find with Chrome 109 include:
- Support for the "lh" length unit in CSS. The "lh" unit is for expressing CSS lengths relative to the line height.
- Support for the CSS "hyphenate-limit-chars" property to specify the minimum number of characters in a hyphenated word, basically finer grained control over hyphenation.
- Initial support for CHIPS, Cookies Having Independent Partitioned State. CHIPS is part of the plan for dealing with Google's plans on obsoleting third-party cookies. This feature allows for third-party cookies partitioned by top-level site by using the "Partitioned" cookie attribute.
- Origin Private File System (OPFS) on Android.
- WebTransport Bring Your Own Buffer (BYOB) readers support for minimizing buffer copies and reducing memory allocations.
- Support for MathML Core as a language for describing mathematical notation embedded in HTML and SVG.
- Auto range support for variable fonts in font-weight, font-style, and font-stretch descriptors within @font-face rules.
