# Releases Our goal is to provide a stable and reliable experience for our users. Here we document the releases of our services and their features, and we intend for this page to serve as the primary reference for users to find updates and changes to our services. ## Blocky Attestation Service Blocky Attestation Service (Blocky AS) is currently in beta, and we are releasing new version every one to two weeks. We run the latest three versions of the Blocky AS servers concurrently, so that when we stand up a server running Blocky AS version *i*, we take down the server running the version *i-3*. It is upon you as the user to update your the Blocky AS endpoints and code measurements to new versions of the service, so that you can continue to use the service without interruption. Once Blocky AS is out of beta, we will provide a new Long Term Support (LTS) version of the service every two months, and we will maintain the last two LTS versions concurrently. Below you will find lists of new features for each version and the code measurement needed to verify the enclave attested public keys created by each version of the Blocky AS servers. > ⚠️ We do not provide compatibility guarantees between the beta versions. ### Blocky AS v0.1.0-beta.13 **Features** - Added `bky-as plumbing` which contains low-level commands for finer-grained control over `bky-as` workflows - Fixed an issue with serialization of empty function input that led to inconsistent `hash_of_input` values returned by Blocky AS TEE servers **Info** - Date: 2025-11-21 - SDK Commit: f246a3b5fed06a4bb653c788a4d1be5f623adc08 Blocky AS v0.1.0-beta.13 code measurement for the AWS Nitro Enclave platform from [v0.1.0-beta.13/code_measurement.toml](/v0.1.0-beta.13/code_measurement.toml): ```toml code_measurement = [ { platform = "nitro", code = "2ca77d31730c113d8c4c7d271d1bea7964655391971df4e217b7ee33bbc9404e75a82d61eb0e8cb34492d7d074ed3173.9d25d9bd4d6e169601901391b4400f9ca6b6636f2ef48e18b38d095757071a3b2aff1352ea3fc406d853a4e587bc7ce3.f32a96a70f8733bef245e2b1d90323b385fe9ced9f4bfa20f81719c9ae1fd1eba82ac47ec72d40314d2fc5a88c8b0ebf" }, ] ``` ### Blocky AS v0.1.0-beta.12 **Features** - Implemented 500KB limit on maximum HTTP request size in WASM runtime.
