* update gogo/protobuf version from v1.2.1 to v1.3.0 Also errcheck from v1.1.0 to v1.2.0 See full diff in - https://github.com/gogo/protobuf/compare/v1.2.1...v1.3.0 - https://github.com/kisielk/errcheck/compare/v1.1.0...v1.2.0 Changelog: Tested versions: go 1.12.9 protoc 3.7.1 Improvements: plugin/stringer - Handle repeated and/or nullable types a bit better now. plugin/size - Remove the loop in sovXXX by using bit twiddling. Thanks: https://github.com/apelisse plugin/marshalto - Implemented a reverse marshal strategy which allows for faster marshalling. This now avoids a recursive (and repeated) call to Size(). Thanks: https://github.com/apelisse plugin/compare - Added support for for oneof types. Bug fixes: protoc-gen-gogo/generator - Fix assignment to entry in nil map. Thanks: https://github.com/tgulacsi protoc-gen-gogo/generator - Allows plugins to call RecordTypeUse without panicking. Thanks: https://github.com/fedenusy proto/extensions - Fixed set extension regression. We did not clear the extensions before setting. io/uint32 - fix uint32reader bug that causes ReadMsg to recreate buffer when lengths are the same.

Tendermint
Byzantine-Fault Tolerant State Machines. Or Blockchain, for short.
Branch | Tests | Coverage |
---|---|---|
master |
Tendermint Core is Byzantine Fault Tolerant (BFT) middleware that takes a state transition machine - written in any programming language - and securely replicates it on many machines.
For protocol details, see the specification.
For detailed analysis of the consensus protocol, including safety and liveness proofs, see our recent paper, "The latest gossip on BFT consensus".
Releases
NOTE: The master branch is now an active development branch (starting with v0.32
). Please, do not depend on it and
use releases instead.
Tendermint is being used in production in both private and public environments, most notably the blockchains of the Cosmos Network. However, we are still making breaking changes to the protocol and the APIs and have not yet released v1.0. See below for more details about versioning.
In any case, if you intend to run Tendermint in production, please contact us and join the chat.

Versioning
Semantic Versioning
Tendermint uses Semantic Versioning to determine when and how the version changes. According to SemVer, anything in the public API can change at any time before version 1.0.0
To provide some stability to Tendermint users in these 0.X.X days, the MINOR version is used to signal breaking changes across a subset of the total public API. This subset includes all interfaces exposed to other processes (cli, rpc, p2p, etc.), but does not include the in-process Go APIs.
That said, breaking changes in the following packages will be documented in the CHANGELOG even if they don't lead to MINOR version bumps:
- crypto
- types
- rpc/client
- config
- node
- libs
- bech32
- common
- db
- errors
- log
Exported objects in these packages that are not covered by the versioning scheme
are explicitly marked by // UNSTABLE
in their go doc comment and may change at any
time without notice. Functions, types, and values in any other package may also change at any time.
Upgrades
In an effort to avoid accumulating technical debt prior to 1.0.0, we do not guarantee that breaking changes (ie. bumps in the MINOR version) will work with existing tendermint blockchains. In these cases you will have to start a new blockchain, or write something custom to get the old data into the new chain.
However, any bump in the PATCH version should be compatible with existing histories (if not please open an issue).
For more information on upgrading, see UPGRADING.md
