Hey Scott

Wondering what features there are for moving to SLDS v2, this is from the Abridge Release Notes:

If you haven’t migrated to SLDSv2 yet, the SLDS Linter which you can install from here helps you find issues in your code and uplift your repo to v2. The SLD Validator will help you ensure you do good quality components from VSCode directly. (now GA, and yes I just copypasted the last release because I didn’t feel like rewriting this). Also DarkMOde and density-aware components for SLDSV2, also usable in VF

Cheers

Hi, Tony. As far as I can tell, the main things that are important for SLDS v2 support are an up-to-date SLDS CSS file and SLDS Linter support to help guide toward the SLDS v2 classes/patterns. I’m already well into a set of Winter ‘26 updates that include the former, and the latter is already available in IC:

You might just need to bump the following to the highest available versions in the project’s package.json file:

"@salesforce-ux/eslint-plugin-slds": "^0.5.3", "@salesforce-ux/stylelint-plugin-slds": "^0.5.3",

IC can also do that for you using the SLDS Linter code inspection settings by clicking Node Dependencies | Reinstall.

If there are other aspects of SLDS v2 support that can/should be integrated directly into IC but aren’t part of what I’ve described above, definitely let me know about those oversights so that I can take care of them.
