v24.1: 24.1

Compare Source

This is bugfix release for 24.

Main change is #​3994: If you have defer enabled (an experimental feature) and use data loaders for mutations your requests would hang, because the data loaders are not dispatched correctly.

Additionally this release contains #​3995.

Cheers

v24.0: 24.0

Compare Source

24.0 is a breaking change

This release is an unexpected breaking change release. It was made to help propagate a fix in the DataLoader library

In DataLoader version 4.0.0 we introduced immutability into the DataLoaderOptions class, which was a good thing.

However it left the old mutative setXXX methods in place and made them immutable. This was a mistake. This leads to bugs at runtime for example

DataLoaderOptions options = DataLoaderOptions.newOptions();
if (maxBatchSize != BatchLoader.UNSET_BATCH_SIZE) {
  options.setMaxBatchSize(maxBatchSize);
}
return options.setCacheMap(cache);

The above code would continue to compile but the setMaxBatchSize() would never take affected at runtime with the immutable support.

So to help address this bug a DataLoader version 5.0.0 was released and it has removed the setXXX methods and requires the Builder methods to be used to ensure that code that relied on the old mutative methods now break at compile time and not at runtime.

In turn we have released this new version of graphql-java - we have designated it a breaking change because of this transitive DataLoader breaking change

We consider v23.x poisoned and we don't recommend you use it because of the latent bug above.

But the release notes of 23 are still relevant when you upgrade from 22: https://github.com/graphql-java/graphql-java/releases/tag/v23.0

Small performance fixes

There are also a set of small performance oriented fixes that have gone out in this release.
