Mainnet 1.1.3 (2021-02-15) (was Testnet 1.1.3 (2021-02-11))

This is a maintenance (non-enclave) release of Fog only.

What's New and Different

👷 Postgres retries

This includes a patch to make our software automatically retry postgres connections and operations a few times if there are retriable connectivity issues.

👷‍♀️ Configurable Oram size

This includes a patch to replace a hard-coded constant in the untrusted side of fog view with a configurable parameter for the ORAM capacity of the server. This is necessary because the size of the blockchain is approaching the limit we launched with initially.

Release Schedule and Advice

We pushed this to testnet on 02-11-2021.
We plan to push this to mainnet on 02-15-2021.

Independent clients which depend on those values (e.g. those doing MRENCLAVE in particular) should add the values included to their trust story (and accept Intel Attestation Verification Reports [AVRs] with SOFTWARE_HARDENING_NEEDED for INTEL-SA-00334, as those enclaves were built with the relevant hardening).

The measurements of all enclaves are exactly the same as v1.1.0 release.

Mainnet 2022-01-21 (Testnet 2021-12-16)

This is a maintenance (non-enclave) release of Fog only.

What's New and Different

👷 Better defaults and configuration for postgres connections

We exposed many diesel parameters, which influence postgres connection timeouts, as environment variables and gave them better defaults. This may help us to make better connections to postgres.

👷‍♀️ Adjustments to logging

• Less logging around things that are not actionable (PERMISSION_DENIED)
• More logging around different activities in fog ingest that help us debug it

Release Schedule and Advice

We are (tentatively) pushing out a release to the fog deployments tomorrow (Jan 21 2022).
Consensus will not be touched and users should see no disruption.

(We pushed this to testnet on Nov 19 2021)

The measurements of all enclaves are exactly the same as v1.1.0 release.

Alpha v1.1.2-pre1

This release contains fixes for:

• Postgres connection settings not configurable
• Insufficient info-level logging in fog ingest
• Too much logging around permission denied / attestation errors that aren't actionable

Alpha v1.1.2-pre0

This release contains fixes for:

• Postgres connection settings not configurable
• Insufficient info-level logging in fog ingest

Mainnet 2021-11-18

This is the first bug fix release to Fog since it was publicly launched.

What's New and Different

👷 Bug fix for Fog-View error codes.

Fixed a bug where Fog-view would return INTERNAL_ERROR instead of PERMISSION_DENIED when attestation fails. This will cause clients not to re-attest appropriately when attestation fails.

👷‍♀️ Adjustments to logging

We stopped logging PERMISSION_DENIED as this is not actionable, and we increases logging for the fog ingest worker loop to help debug when it is stuck

Release Schedule and Advice

We are may push out this release to the fog deployments tomorrow (Jan 21 2022).
But there is also the possibility that it will be delayed.
Consensus will not be touched and users should see no disruption.

The measurements of all enclaves are exactly the same as v1.1.0 release.

TestNet 2021-11-17

Fog release only

Alpha v1.1.1-pre0

This contains fixes for:

• Fog view was not returning "PermissionDenied" rpc errors for attestation errors
• Fog ingest was updating the report cache much more often than necessary

Fog 1.1.0

Hey all, this is the first incremental release of MobileCoin since launch of mainnet.

What's New and Different

✨ Sticky Sessions for gRPC Clients

We now support cookie-based load balancing at the gRPC layer when connecting to fog enclaves.

👷 Newer Rust (nightly-2021-03-25)

We've updated our supported rust version to one released after stable-0.51.0.

🔒 ⬆️ SGX 2.13.3

We've updated the version of the SGX SDK we're using to 2.13.3, to address INTEL-SA-00477, which is a timing attack vulnerability in some Intel crypto code.

Release Schedule and Advice

We are pushing out a release today, and will be coordinating with network operators to deploy the new version of Consensus network and Fog servers (enclaves) on or before July 14, 2021 (exact date TBD).

A more detailed changelog is also available.
