Block Public Access | You can allow public access to OSS resources by configuring bucket policies and access control lists (ACLs). Public access specifies access to OSS resources without specific permissions or authentication. Public access can cause data breaches and generate a large amount of outbound traffic over the Internet due to malicious access. To prevent risks caused by public access, OSS allows you to enable Block Public Access with a few steps for OSS, a bucket, an access point, and an Object FC Access Point. If you enable Block Public Access, existing public access permissions are ignored and you cannot configure public access permissions. This disables public data access channels and ensures data security. | 2024-04-11 | All regions |

Object FC Access Point | If you want OSS to automatically trigger Function Compute when you initiate a GetObject request and return the transformed result of the retrieved data to the application, you must initiate the request by using an Object FC Access Point. You can initiate requests by using Object FC Access Points to seamlessly modify or filter the content of objects without the need to change object storage semantics or modify the client. | 2023-10-31 | China (Qingdao) | |
CRR | Cross-region replication (CRR) across accounts and same-region replication (SRR) across accounts allow the automatic and asynchronous (near real-time) replication of OSS objects from a bucket within an Alibaba Cloud account to another bucket within another Alibaba Cloud account. CRR across accounts requires that the source and destination buckets be located in different regions, and SRR across accounts requires that the source and destination buckets be located in the same region. CRR across accounts and SRR across accounts replicate operations, such as the creation, overwriting, and deletion of objects, from a source bucket to a destination bucket. | 2023-10-17 | All regions |

TLS version management | Communication between client applications and OSS is encrypted by using the transport layer security (TLS) protocol. TLS is a standard cryptographic protocol that ensures privacy and data integrity between clients and servers that communicate over the Internet. You can use an OSS server to configure the TLS version. After you configure the TLS version, clients can use only the configured TLS version to send requests to and receive requests from OSS to meet the security requirements of the communication link. | 2023-09-19 | All regions |
