NOTE: This release is not yet an official ASF release. We are still in the process of learning how to create a formal one.

Upgrade to v0.31

In version v0.31 of OpenDAL, we made some internal refactoring to improve its compatibility with the ecosystem.

MSRV Bump

We increased the MSRV to 1.64 from v0.31 onwards. Although it is still possible to build OpenDAL under older rustc versions, we cannot guarantee that any issues related to them will be fixed.

Accept `std::time::Duration` instead

Previously, OpenDAL accepted time::Duration as input for presign_xxx. However, since v0.31, we have changed this to accept std::time::Duration so that users do not need to depend on time. Internally, we migrated from time to chrono for better integration with other parts of the ecosystem.

`disable_ec2_metadata` for services s3

We have added a new configuration option called disable_ec2_metadata for the S3 service in response to a mistake where it was mixed up with another option called disable_config_load. Users who want to disable loading credentials from EC2 metadata should set this option instead.

Services Feature Flag

Starting from v0.31, all services in OpenDAL are split into different feature flags. To enable only S3 support, use the following TOML configuration:

opendal = {
    version = "0.31",
    default-features = false,
    features = ["services-s3"]
}
