This release supersedes v0.38.14
, which mistakenly updated the Go version to
1.23
, introducing an unintended breaking change. It sets the Go version back
to 1.22.7
by reverting #4297.
The release includes the bug fixes, performance improvements, and importantly,
the fix for the security vulnerability in the vote extensions (VE) validation
logic that were part of v0.38.14
. For more details, please refer to ASA-2024-011.
November 6, 2024
This release fixes a security vulnerability in the vote extensions (VE) validation logic. For more details, please refer to ASA-2024-011.
We recommend upgrading ASAP if you’re using vote extensions (VE).

October 24, 2024
This patch release addresses the issue where tx_search was not returning all results, which only arises when upgrading to CometBFT-DB version 0.13 or later. It includes a fix in the state indexer to resolve this problem. We recommend upgrading to this patch release if you are affected by this issue.

Fix the tx_search results not returning all results by changing the logic in the indexer to copy the key and values instead of reusing an iterator. This issue only arises when upgrading to cometbft-db v0.13 or later. (#4295). Special thanks to @faddat for reporting the issue.

This release reverts the API-breaking change to the Mempool interface introduced in the last patch release (v0.38.8) while still keeping the performance improvement added to the mempool. It also includes a minor fix to the RPC endpoints /tx and /tx_search.
[mempool]
Revert adding the methodPreUpdate()

January 24, 2024
This release fixes a problem introduced in v0.38.3
: if an application
updates the value of ConsensusParam VoteExtensionsEnableHeight
to the same value
(actually a "noop" update) this is accepted in v0.38.2
but rejected under some
conditions in v0.38.3
and v0.38.4
. Even if rejecting a useless update would make sense
in general, in a point release we should not reject a set of inputs to
a function that was previuosly accepted (unless there is a good reason
for it). The goal of this release is to accept again all "noop" updates, like v0.38.2
did.
[consensus]
Addchain_size_bytes

January 22, 2024
This release is aimed at those projects that have a dependency on CometBFT,
release line v0.38.x
, and make use of function SaveBlockStoreState
in package
github.com/cometbft/cometbft/store
. This function changed its signature in v0.38.3
.
This new release reverts the signature change so that upgrading to the latest release
of CometBFT on v0.38.x
does not require any change in the code depending on CometBFT.
[e2e]
Add manifest optionVoteExtensionsUpdateHeight
to test vote extension activation viaInitChain

January 17, 2024
This release addresses a high impact security issue reported in advisory
(ASA-2024-001).
There are other non-security bugs fixes that have been addressed since
v0.38.2
was released, as well as some improvements.

This release provides the nop mempool for applications that want to build their own mempool.
Using this mempool effectively disables all mempool functionality in CometBFT, including transaction dissemination and the broadcast_tx_*
endpoints.
Also fixes a small bug in the mempool for an experimental feature.

September 12, 2023
This release includes the second part of ABCI++, called ABCI 2.0.
ABCI 2.0 introduces ABCI methods ExtendVote
and VerifyVoteExtension
.
These new methods allow the application to add data (opaque to CometBFT),
called vote extensions to precommit votes sent by validators.
These vote extensions are made available to the proposer(s) of the next height.
Additionally, ABCI 2.0 coalesces BeginBlock
, DeliverTx
, and EndBlock
into one method, FinalizeBlock
, whose Request*
and Response*
data structures contain the sum of all data previously contained
in the respective Request*
and Response*
data structures in
BeginBlock
, DeliverTx
, and EndBlock
.
See the specification for more details on ABCI 2.0.

This is the first CometBFT release with ABCI 1.0, which introduces the
PrepareProposal
and ProcessProposal
methods, with the aim of expanding the
range of use cases that application developers can address. This is the first
change to ABCI towards ABCI++, and the full range of ABCI++ functionality will
only become available in the next major release with ABCI 2.0. See the
specification for more details.
In the v0.34.27 release, the CometBFT Go module is still
github.com/tendermint/tendermint
to facilitate ease of upgrading for users,
but in this release we have changed this to github.com/cometbft/cometbft
.
Please also see our upgrading guidelines for more details on upgrading from the v0.34 release series.
Also see our QA results for the v0.37 release.
We'd love your feedback on this release! Please reach out to us via one of our communication channels, such as GitHub Discussions, with any of your questions, comments and/or concerns.
