I design internal web tools for a company, and we use Vue and Vuetify on the front-end. I use a material design plugin with Sketch and have created our own beginnings of a design system/style guide that follows our brand guidelines with our own colors. Otherwise we generally adhere to Material Design. Vuetify is great for our dev team to make UIs quickly, but with each new version it seems like they update the visual design of components. This makes UIs with different versions inconsistent.
I'm wondering if other in-house design teams are doing something similar, primarily using an open-source UI framework that changes their visual design with additional versions? At what point do you push your dev team to move away from said framework or stop at a certain version to keep UIs visually consistent as we continue to build sections of our internal product with consistency in mind? The dev team likes new components and niceties of newer versions though.
Hoping to get some advice on what to do about this - thank you.
