[release] MUI Joy 5.0.0-beta.50

[DiegoAndai]

Release for React 19 support. Dev dependencies haven't been updated yet but that shouldn't impact end users.

I checked with pnpm release:changelog and there are no Joy-specific commits since the last release from this branch (which was alongside 5.16.1)

@DiegoAndai
probably you already know...
anyway the released 5.0.0-beta.50 still depends on react17 || react 18:

material-ui/packages/mui-joy/package.json

Lines 66 to 72 in 5dede3d

	"peerDependencies": {
	"@emotion/react": "^11.5.0",
	"@emotion/styled": "^11.3.0",
	"@types/react": "^17.0.0 || ^18.0.0",
	"react": "^17.0.0 || ^18.0.0",
	"react-dom": "^17.0.0 || ^18.0.0"
	},

so it gives this error on a new react19 project:

the latest version of packages/mui-joy/package.json fixed it:

material-ui/packages/mui-joy/package.json

Lines 66 to 72 in dd990df

	"peerDependencies": {
	"@emotion/react": "^11.5.0",
	"@emotion/styled": "^11.3.0",
	"@types/react": "^17.0.0 || ^18.0.0 || ^19.0.0",
	"react": "^17.0.0 || ^18.0.0 || ^19.0.0",
	"react-dom": "^17.0.0 || ^18.0.0 || ^19.0.0"
	},

is a beta.51 release planned soon?

for anyone hitting this issue, meanwhile I'm using an override in my package.json:

"overrides": {
    "COMMENT_@mui/joy": "@mui/[email protected] supports react 19 but still have peer dependencies on react 18...",
    "@mui/joy":{
      "@types/react": "^19",
      "@types/react-dom": "^19",
      "react": "^19",
      "react-dom": "^19"
    }
  }

Hey @beppemarazzi, thanks for reaching out. We're working out the last details for fixing the peer dependencies. It should be available soon.
