mongo-go-driver v1.4.0-beta1 Release Notes
Release Date: 2020-04-10 // about 4 years ago-
🚀 The MongoDB Go driver team is pleased to release 1.4.0-beta1 of the official Go driver.
🚀 This release contains support for some MongoDB server version 4.4 features and improvements to the driver API.
📚 Documentation can be found on pkg.go.dev and the MongoDB documentation site. BSON library documentation is also available on pkg.go.dev. Questions and inquiries can be asked on the MongoDB Developer Community. Bugs can be reported in the Go Driver Jira where a list of current issues can be found.
Context for BSON Errors
🚀 In previous versions, unmarshalling BSON bytes into a struct could fail with errors like
cannot decode string into int32 type. These errors lacked context and could be confusing to debug. This release adds context to these errors to provide both the BSON key and the struct field name which caused the error. A similar error is now in the formerror decoding key foo(fieldFoo): cannot decode string into int32 type.🚀 Release Notes
