# Handshake Developer Call 5/28/2020 ## News ### Bob Wallet Release Candidate Bob Wallet is one of the more important pieces of the Handshake ecosystem and a new release candidate was recently cut. If users could test and give feedback it would be greatly appreciated. https://github.com/kyokan/bob-wallet/releases/tag/v0.2.9-rc.1 ### New `hsd` Node RPC `getdnssecproof` This RPC will build and optionally verify the DNSSEC proof that is required to claim a name. Useful for users that want to claim their name and test whether or not their DNSSEC proof is set up properly. [Commit](https://github.com/handshake-org/hsd/commit/f69cf3122e43da619a5db851a8cc27a6671002f0) [Docs](https://hsd-dev.org/api-docs/#getdnssecproof) ### Bugfix: Allow Bids With Bids/Blinds of 0 Previously an assertion would prevent the wallet HTTP endpoints from creating bid outputs with values or blinds of value 0. [Commit](https://github.com/handshake-org/hsd/commit/8c7053e45be78be638455e935dff7a8f8c3a5f4d) ### New `hsd` HTTP Endpoint `GET /header` Users can call `GET /header/:heightOrHash` to fetch a block header by height of by hash. This is useful for SPV nodes that do not index the full blocks.
