v2.0.3

BandChain

Laozi Mainnet Release

BandChain

• All extra features e.g. emitter, flusher, request search, etc. are now removed from master branch and have been located in extra/rest branch instead, so that validators who don't need those extra features don't have to compile unused dependencies. [#120] However, protobuf files should be the same between extra/rest and master branch to provide consistency.
• Editing oracle scripts / data sources can now change owner address [#106]
• Fix typo [#103] [#114] [#124]
• Refactor code [#105] [#108] [#118]
• Validate max gas used by oracle script [#107]
• Reporter has been set twice [#117]
• Bring back REST endpoints for querying chain ID and EVM validators [#116]
• Improve unit test [#113]

Yoda

• Improve gas estimation [#92]

IBC

• Use failed event instead of panic when error occurred during sending packets [#121]
• Change default channel version [#104]
• Improved tests [#90] [#108]
• Refactor code [#122]

v2.0.0-rc2

WARNING: DO NOT USE master BRANCH FOR DEPLOYING LAOZI TESTNET 1

Since there is a PR #84 that changed the encoding format of oracle results from OBI-encoded to protobuf, the PR breaks the consensus state! Therefore, please keep in mind that use laozi-testnet1 branch or this tag when upgrading Laozi testnet.

Changelog

Yoda

• [#91] Fix broadcastTx transaction that uses the same sequence number, causing Yoda unable to query transaction status since the tx already rejected during CheckTx. (This bug only exists on Laozi testnet, not the current mainnet).

BandChain

• [#83] bandd query oracle active-validators command is now returning list of active validators instead of count number 🎉
• [#86] A flag --with-pricer has been migrated to Laozi version. Use bandd query oracle request-price to query results from the local db.
• [#85] Refactor code of Hooks.

Emitter

• [#78] Add emitter hook for handling transfer tokens via IBC.

v2.0.0-rc1

Yoda

Bandchain

• (#72) Added CLI command/gRPC to query validator status
• (#73) Added CLI command/gRPC for querying pending requests

Emitter

• (#80) Optimize oracle response time query
• (#79) Fix bug remove reporter
