Proposal

Style Dictionary needs a few updates to align with the newly-published v2025.10 version of the specification. Some are captured in open issues, some I’m proposing in this issue:

• Color: support the new color module ✅
• Border: support new color module ✅
• Shadow: support new color module ✅
• Gradient: support new color module 🚧
• Dimension: Incorrect/unexpected output for $dimension token types when using DTCG format spec #1398 (and Update the SizePX format for the “dimension” token when using the DTCG format with a unit specification. #1501 and design tokens spec dimension tokens #1584) -> ✅
• Duration: 🚧 Add Support for Motion Tokens in DTCG Format with Nested Object Structure #1471
• Resolvers: support the new resolver module

Questions

• Would this constitute a new breaking major release? Or should Style Dictionary support legacy editors drafts and v2025.10 at the same time?
• Which editors drafts should be still supported, in addition to v2025.10? (Are there any difficulties with this?)
• Outside of DTCG format, is there any Style Dictionary JSON that may be particularly tricky / may be broken as a result of some of these changes (I genuinely don’t know, but wanted to ask if anything comes to mind)?

Would love to help contribute to provide support for this. 🙂
