Hello there 
Q2 has come to a close, and what a whirlwind it’s been! This quarter flew by with a host of exciting new features and important bug fixes.
polkadot-api@1.14.0 Updates
Archive Support
The headline feature of this release is transparent archive support. Whenever the RPC node offers archive_v1 methods and the target block isn’t pinned, we’ll automatically use those calls, allowing you to query any historical block. One caveat: the block’s metadata version must be at least v14.
This feature was highly requested by the community, but we waited until archive functionality was broadly available across nodes. Give it a spin!
Other Fixes
We also tackled several maintenance items:
- Transaction validation logic
Previous PAPI versions (prior to 1.14) didn’t consider the mortality block hash during validation. As a result, some transactions were wrongly marked invalid if they originated from a non-parent block. This has been corrected, and most users won’t notice a change, but edge cases are now handled properly. - Improved error handling for non-pinned blocks
While integrating archive support, we discovered and fixed an issue with error messages when querying non-pinned blocks.
SDK Work
Remote Proxy SDK
We’ve been heads-down on the Remote Proxy SDK, which makes integrating with the Remote Proxy pallet (currently on Kusama) a breeze. Now you can authorize Asset Hub transactions using proxies on the relay chain. Check out our detailed forum post on Remote Proxies for Everyone for all the details!
Revive
Since our last update, we’ve completed full compatibility with the Revive pallet and continue to share feedback on its upstream development.
Smoldot
We collaborated with @tomaka this month to build a new Smoldot feature: getting storage proofs directly from the light client! This feature will enable the Remote Proxy SDK with the light client, delivering stronger security and lower trust requirements. Amazing progress, and it is soon to be completed! Thanks for your detailed reviews Pierre!
Protocol BERG
Earlier in June, the team attended Protocol BERG—a fantastic conference on Web3 technical challenges. We learned tons and met several key members of the Polkadot community. Big thanks to the organizers for a great event!
Thank you for your continued feedback, and talk to you next month!
