Release Notes

Bumped bson version to make use of new Decimal128 behaviour

In this release, we have adopted the changes made to Decimal128 in bson version 5.5. The Decimal128 constructor and fromString() methods now throw when detecting a loss of precision (more than 34 significant digits). We also expose a new fromStringWithRounding() method which restores the previous rounding behaviour.

See the bson v5.5.0 release notes for more information.

Use region settings for STS AWS credentials request

When using IAM AssumeRoleWithWebIdentity AWS authentication the driver uses the @​aws-sdk/credential-providers package to contact the Security Token Service API for temporary credentials. AWS recommends using Regional AWS STS endpoints instead of the global endpoint to reduce latency, build-in redundancy, and increase session token validity. Unfortunately, environment variables AWS_STS_REGIONAL_ENDPOINTS and AWS_REGION do not directly control the region the SDK's STS client contacts for credentials.

The driver now has added support for detecting these variables and setting the appropriate options when calling the SDK's API: fromNodeProviderChain().

[!IMPORTANT] The driver will only set region options if BOTH environment variables are present. AWS_STS_REGIONAL_ENDPOINTS MUST be set to either 'legacy' or 'regional', and AWS_REGION must be set.

Fix memory leak with ChangeStreams

In a previous release, 5.7.0, we refactored cursor internals from callbacks to async/await. In particular, the next function that powers cursors was written with callbacks and would recursively call itself depending on the cursor type. For ChangeStreams, this function would call itself if there were no new changes to return to the user. After converting that code to async/await each recursive call created a new promise that saved the current async context. This would slowly build up memory usage if no new changes came in to unwind the recursive calls.

The function is now implemented as a loop, memory leak be gone!
