v3.0.0

This is a major release.

Breaking

• Minimum node v18
• Removes .redirect('back'), adds .back(fallback_url) @​fl0w koajs/koa#1115
• For .redirect(), don't render redirect values in anchor ref koajs/koa@ff25eb4
• req.origin should display the origin header if it exists, not the current hostname koajs/koa#1008. origin now aligns with the Origin header as used in CORS.
• .body=<json> should not overwrite type if type already json koajs/koa#1120
• Remove special ENOENT support koajs/koa#1861 - this is a big change and will require any file servers to adapt to this change for handling 404s / files not found
• Removes generator deprecation messages. Generators are no longer supported. Koa no longer asserts if generators are used. Set content-length: 0 if body is explicitly set to null @​ognjenjevremovic #1528 Remove obsolete createAsyncCtxStorageMiddleware koajs/koa#1817
• ctx.throw now requires a format of ctx.throw(status, error, properties). See: https://www.npmjs.com/package/http-errors
