@urql/[email protected] Deprecations

[kitten]

Hiya! 👋

You may have noticed that we just shipped @urql/[email protected] with some deprecations.

Specifically, this version of @urql/core renames Operation.operationName to Operation.kind. For now the old
property is merely deprecated and will issue a warning if it's used directly. That said, all
exchanges that are released today also need this new version of @urql/core@>=1.14.0, so if you
upgrade any exchanges today, you will also need to upgrade @urql/core. If you upgrade
and see the deprecation warning, check whether all exchanges have been upgraded.

Once you've upgraded @urql/core please also ensure that your package manager hasn't accidentally
duplicated the @urql/core package. If you're using npm you can do so by running npm dedupe,
and if you use yarn you can do so by running yarn-deduplicate.

If you have a custom exchange, you can mute the deprecation warning by using Operation.kind rather
than Operation.operationName. If these exchanges are copying or altering operations by spreading
them this will also trigger the warning, which you can fix by using the new makeOperation helper
function.

On a side note, this batch of releases also fixes Webpack 5 support, so make sure to upgrade, if you're using Webpack 5. Otherwise you may see some resolution errors soon.
