PocketIC has rolled out version 11.0.0 of its server alongside updated Rust, Python and JavaScript libraries, expanding its feature set for developers building and testing on the Internet Computer. The release introduces support for Dogecoin and canister migration, alongside a series of tooling updates aimed at improving local and simulated environments.
The latest server release is accompanied by Rust library version 11.0.0, Python library version 3.1.1 and JavaScript library version 0.17.0. Together, they align PocketIC’s core components and ensure compatibility across commonly used development stacks.
A key addition in this release is support for deploying Bitcoin testnet, Dogecoin mainnet and Network Nervous System migration canisters during PocketIC instance creation. This allows developers to test interactions with multiple networks and migration scenarios without relying on live environments, a practical gain for teams working on more complex workflows.
PocketIC 11.0.0 also adds support for downloading and uploading canister snapshots using the same file format as dfx. This brings local testing closer to real deployment conditions and simplifies moving state between environments. For developers working with known mainnet canisters, the update introduces the option to use and update the mainnet routing table when creating canisters with mainnet canister IDs, reducing friction when mirroring production setups.
While the release focuses on infrastructure rather than end-user features, it reflects an ongoing effort to make PocketIC a closer approximation of mainnet behaviour. That matters for developers who rely on predictable testing when working with system-level features such as migrations and cross-network interactions.
The team has encouraged users to review the full server and Rust library changelogs for a detailed breakdown of changes and has invited feedback to guide future updates. As PocketIC continues to evolve, the emphasis remains on practical tooling that shortens development cycles while keeping testing environments aligned with how applications behave on the Internet Computer itself.
