Hedera will prioritize the inclusion of new capabilities and enhancements in v2 of the official SDKs between now and the time of complete deprecation in October 2021 of the v1 SDK, . If you’re still using v1 of the Hedera SDK, you will see a warning that deprecation is coming and you may not receive access to new capabilities and features as quickly as developers using v2.
Migrating from v1 to v2
New languages and beyond
Officially supported languages for Hedera SDKs are being considered but no concrete decisions have been made. If you’re interested in seeing a specific language officially supported, it’s highly recommended to create a Hedera Improvement Proposal (HIP) with as much detail as possible for both the community and Hedera Hashgraph, Inc. to review and comment. You can find the official HIP repository and instructions here: https://github.com/hashgraph/hedera-improvement-proposal
