The o1Labs team is proud to announce that `3.3.0-beta1` is ready to test on Mainnet! This release includes a significant number of additions and improvements that will form the basis of the upcoming Mesa Upgrade. We have made significant performance improvements to the archive node process which should lower resource consumption considerably. We have also extended our operating system support based on your feedback to include Ubuntu 22.04 LTS (Jammy Jellyfish) and experimental ARM64 support for Ubuntu 24.04LTS (Noble) and Debian 12 (Bookworm). If you run into any issues, please include `Release: 3.3.0-beta1` in the name of any issues you create. Please report any issues you encounter [here](https://github.com/MinaProtocol/mina/issues/new/choose) or join [the discussion](https://github.com/MinaProtocol/mina/discussions/18050)! **Some highlights of what has changed** **New Features** - #17702: [CI] Support for jammy - #16704: Caqti upgrade with fix for rosetta - #17664: [ARM64] adding arm64 for noble and bookworm **Improvements** - #17730: Use stricter error type in Work partitioner - #17758: Push sig kind out of snark profiler lib - #17686: Refactor Snark Worker related metrics generation - #17677: Implement staged ledger checkpointing - #17675: Folding accounts across all ledger masks - #17648: Various helper functions in Snark Work Lib - #17641: Improve Genesis Ledger Creation **Bug fixes** - #17583: Handle submission into work partitioner single pool correctly **Complete Changelog since 3.2.0:** [https://github.com/MinaProtocol/mina/compare/3.2.0...3.3.0-beta1](https://github.com/MinaProtocol/mina/compare/3.2.0...3.3.0-beta1) Supported environments include macOS, Linux (Debian 11, 12 and Ubuntu 20.04 LTS, Ubuntu 22.04 LTS & Ubuntu 24.04 LTS), and any host machine with Docker. 🚨***NOTE - as Ubuntu 20.04 has now reached EOL we will phase this out in future releases***🚨 --- **Upgrading & Connecting to Mainnet** **Debian Packages:** **Debian Repository:** First, set up and update the `beta` Debian Repository for your platform with the following commands: ``` sudo rm /etc/apt/sources.list.d/mina*.list echo "deb [trusted=yes] http://packages.o1test.net $(lsb_release -cs) beta" | sudo tee /etc/apt/sources.list.d/mina-beta.list sudo apt-get update ``` Then, install the package(s) that you need: **Mina Daemon:** `sudo apt-get install --allow-downgrades -y mina-mainnet=3.3.0-beta1-5b0a889` **Mina Archive:** `sudo apt-get install --allow-downgrades -y mina-archive=3.3.0-beta1-5b0a889` **Mina Archive Schema:** [create_schema.sql](https://github.com/MinaProtocol/mina/blob/release/3.3.0/src/app/archive/create_schema.sql) **Config File:** `var/lib/coda/config_5b0a8898.json` **Docker Images:** Every docker image is built for each of the supported platforms, replace `CODENAME` in the images below with your choice of `focal`, `jammy`, `noble`, `bullseye` or `bookworm` to select the base docker image. **Mina Daemon:** `gcr.io/o1labs-192920/mina-daemon:3.3.0-beta1-5b0a889-CODENAME-mainnet` **Mina Archive:** `gcr.io/o1labs-192920/mina-archive:3.3.0-beta1-5b0a889-CODENAME-mainnet` **Mina Rosetta:** `gcr.io/o1labs-192920/mina-rosetta:3.3.0-beta1-5b0a889-CODENAME-mainnet` For experimental ARM64 docker images replace `CODENAME` in the images below with your choice of `noble` or `bookworm` to select the desired image. **Mina Daemon:** `gcr.io/o1labs-192920/mina-daemon:3.3.0-beta1-5b0a889-CODENAME-mainnet-arm64` **Mina Archive:** `gcr.io/o1labs-192920/mina-archive:3.3.0-beta1-5b0a889-CODENAME-mainnet-arm64` **Mina Rosetta:** `gcr.io/o1labs-192920/mina-rosetta:3.3.0-beta1-5b0a889-CODENAME-mainnet-arm64` _**Note**: for ARM64 builds the GIT SHA-1 will be `9c856a80763d55a2de765bac6c96f4c776f7887b`, this is due to changes in our build pipeline during the beta1 release.

The o1Labs team is proud to announce that `3.1.0` has now been released for Mainnet! This release includes a ton of bug fixes, hashing performance enhancements as well as additional code cleanup & general improvements. A very cool addition to this release is an [optimization to the ledger synchronization protocol](https://github.com/MinaProtocol/mina/pull/16093), specifically enhancing how nodes sync their ledger state during a fresh startup, after downtime, or restarting from stale state. The change reduces the number of network roundtrips needed to sync a ledger and therefore makes syncing fast even as the # of accounts in the ledger grows! We have also introduced [enhancements during bootstrapping](https://github.com/MinaProtocol/mina/pull/16216) to reduce empty blocks on node restart. We have also landed some very cool additional work such as a [reduction of the max time](https://github.com/MinaProtocol/mina/pull/16656) to produce a block from >120s down to <45s and some nice items that allow for [resource reductions](https://github.com/MinaProtocol/mina/pull/16201). This release also introduces the ability to spin up custom snark coordinator configurations! Here's [a cool script](https://github.com/MinaProtocol/mina/blob/compatible/scripts/snark_work_strategy.py) that showcases the usage!

The o1Labs team is ready to announce that the `3.0.4` hotfix release for **snark workers** is now available for Mainnet. ### ❗For anyone not running snark workers, this is not a necessary upgrade.❗ This hotfix release fixes an issue with snark worker instances that can be triggered by a very rare edge-case. The issue could in theory cause snark worker nodes to get stuck; as such those running snark workers are strongly encouraged to upgrade their snark worker instances to this version as soon as possible.
