# Changelog
## [Unreleased]
### Client-Breaking Changes
* [\#9859](https://github.com/cosmos/cosmos-sdk/pull/9859) The `default` pruning strategy now keeps the last 362880 blocks instead of 100. 362880 equates to roughly enough blocks to cover the entire unbonding period assuming a 21 day unbonding period and 5s block time.
## [v0.43.0-rc3](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.43.0-rc3) - 2021-08-05
### Bug Fixes
* [\#9720](https://github.com/cosmos/cosmos-sdk/pull/9720) Feegrant grant cli granter now accepts key name as well as address in general and accepts only address in --generate-only mode
* [\#9766](https://github.com/cosmos/cosmos-sdk/pull/9766) Fix hardcoded ledger signing algorithm on `keys add` command.
* [\#9793](https://github.com/cosmos/cosmos-sdk/pull/9793) Fixed ECDSA/secp256r1 transaction malleability.
### Features
* [\#9750](https://github.com/cosmos/cosmos-sdk/pull/9750) Emit events for tx signature and sequence, so clients can now query txs by signature (`tx.signature='<base64_sig>'`) or by address and sequence combo (`tx.acc_seq='<addr>/<seq>'`).
### API Breaking Changes
* (x/capability) [\#9836](https://github.com/cosmos/cosmos-sdk/pull/9836) Removed `InitializeAndSeal(ctx sdk.Context)` and replaced with `Seal()`. App must add x/capability module to the begin blockers which will assure that the x/capability keeper is properly initialized. The x/capability begin blocker must be run before any other module which uses x/capability.
### Improvements
* (cli) [\#9717](https://github.com/cosmos/cosmos-sdk/pull/9717) Added CLI flag `--output json/text` to `tx` cli commands.
### Client-Breaking Changes
* [\#9785](https://github.com/cosmos/cosmos-sdk/issues/9785) Missing coin denomination in logs
### CLI Breaking Changes
* [\#9827](https://github.com/cosmos/cosmos-sdk/pull/9827) Ensure input parity of validator public key input between `tx staking create-validator` and `gentx`.
* [\#9781](https://github.com/cosmos/cosmos-sdk/pull/9781) Improve`withdraw-all-rewards` UX when broadcast mode `async` or `async` is used.
## [v0.43.0-rc2](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.43.0-rc2) - 2021-07-19
### Bug Fixes

### Improvements
* (cli) [\#9593](https://github.com/cosmos/cosmos-sdk/pull/9593) Check if chain-id is blank before verifying signatures in multisign and error.
### Bug Fixes
* (bank) [\#9687](https://github.com/cosmos/cosmos-sdk/issues/9687) fixes [\#9159](https://github.com/cosmos/cosmos-sdk/issues/9159). Added migration to prune balances with zero coins.
### CLI Breaking Changes
* [\#9621](https://github.com/cosmos/cosmos-sdk/pull/9621) Rollback [\#9371](https://github.com/cosmos/cosmos-sdk/pull/9371) and log warning if there's an empty value for min-gas-price in app.toml

# Cosmos SDK v0.43.0-RC3 Release Notes
# Cosmos SDK v0.43.0 Release Notes
This is a fourth Release Candidate for v0.43. If no issue will be reported this will be the final release.
This release introduces several new important updates to the Cosmos SDK. The release notes below provide an overview of the larger high-level changes introduced in the v0.43 release series.
This release contains two major bug fixes:
That being said, this release does contain many more minor and module-level changes besides those mentioned below. For a comprehsive list of all breaking changes and improvements since the v0.42 "Stargate" release series, please see the [CHANGELOG](https://github.com/cosmos/cosmos-sdk/blob/v0.43.0/CHANGELOG.md).
- This release includes an important `x/capabiliy` module bug fix which prohibited IBC to create new channels (issue [\#9800](https://github.com/cosmos/cosmos-sdk/issues/9800)).
The fix introduces an API-breaking change by removing the `x/capability/keeper/Keeper.InitializeAndSeal` method and replaces it with `Seal()`. It also requires app developers to update their app module manager by adding x/capability module to `BeginBlocker`s before any other module's `BeginBlocker`.
- [\#9793](https://github.com/cosmos/cosmos-sdk/pull/9793) Fixed ECDSA/secp256r1 transaction malleability.
## Two new modules: `x/authz` and `x/feegrant`
One **client-breaking change** has also been introduced to fix an emitted event:
The v0.43 release focused on simplifying [keys and fee management](https://github.com/cosmos/cosmos-sdk/issues/7074) for SDK users, by introducing the two following modules:
- [\#9785](https://github.com/cosmos/cosmos-sdk/issues/9785) Fix missing coin denomination in logs when emitting the `create_validator` event.
- `x/feegrant` allows one account, the "granter" to grant another account, the "grantee" an allowance to spend the granter's account balance for fees within certain well-defined limits. It solves the problem of signing accounts needing to possess a sufficient balance in order to pay fees.
- See [ADR-029](https://github.com/cosmos/cosmos-sdk/blob/8f21e26a6506c9ee81686bad6cf9be3f0e8e11d7/docs/architecture/adr-029-fee-grant-module.md) introducing the module.
- Read the [documentation](https://docs.cosmos.network/master/modules/feegrant/).
- Check out its [Protobuf definitions](https://github.com/cosmos/cosmos-sdk/tree/master/proto/cosmos/feegrant/v1beta1).
- `x/authz` provides functionality for granting arbitrary privileges from one account (the "granter") to another account (the "grantee"). These privileges, called [`Authorization`](https://github.com/cosmos/cosmos-sdk/blob/f2cea6a137ce19ad8987fa8a0cb99f4b37c4484d/x/authz/authorizations.go#L11)s in the code, can for example allow grantees to execute `Msg`s on behalf of the granter.
- See [ADR-030](https://github.com/cosmos/cosmos-sdk/blob/8f21e26a6506c9ee81686bad6cf9be3f0e8e11d7/docs/architecture/adr-030-authz-module.md) introducing the module.
- Read the [documentation](https://docs.cosmos.network/master/modules/authz/).
- Check out its [Protobuf definitions](https://github.com/cosmos/cosmos-sdk/tree/master/proto/cosmos/authz/v1beta1).
It also includes a couple of minor fixes and improvements:
These two modules have a slightly different folder structure compared to previously existing modules. For example, all Protobuf-generated files are generated in the module root folder instead of the `types/` folder, and the module itself is defined inside a `module` sub-package. Moving forward, we believe this folder structure is clearer and sets a better example for module developers. To learn more about building modules following this structure, please read our [building modules](https://docs.cosmos.network/master/building-modules/intro.html) documentation.
- [\#9750](https://github.com/cosmos/cosmos-sdk/pull/9750) Emit events for tx signature and sequence, so clients can now query txs by signature (`tx.signature='<base64_sig>'`) or by address and sequence combo (`tx.acc_seq='<addr>/<seq>'`).
- Multiple CLI UX improvements. Notably, we changed `<app> tx distribution withdraw-all-rewards` CLI by forcing the broadcast mode if a chunk size is greater than 0. This will ensure that the transactions do not fail even if the user uses invalid broadcast modes for this command (sync and async). This was requested by the community and we consider it as fixing the `withdraw-all-rewards` behavior.
## ADR-028 Addresses
Please see the [CHANGELOG](https://github.com/cosmos/cosmos-sdk/blob/release/v0.43.x/CHANGELOG.md) for more details.
In the SDK versions v0.42 and earlier, addresses were all 20-bytes long, generated by truncating the first 20 bytes of the SHA-256 hash of some given bytes (e.g. the public key for normal accounts, or the module name for module accounts). Unfortunately, this significantly decreases the security of Cosmos SDK due to address space collisions.
ADR-028 introduces a new specification for deriving addresses for all kinds of addressable accounts. Following is a quick summary:
- secp256k1 public keys still have 20-byte addresses to keep backwards-compatibility,
- new public key types (e.g. ed25519) and module accounts will have 32-byte address to increase collision resistance,
- new algorithms have also been specified for composed accounts (like multisigs) or derived accounts (like module sub-accounts).
[Link to ADR-028](https://github.com/cosmos/cosmos-sdk/blob/master/docs/architecture/adr-028-public-key-addresses.md).
## ADR-041 In-place store migrations
Chain upgrades were historically done with the Cosmos SDK by creating an upgrade proposal, halting the chain at the given height, exporting state to a JSON file, making the necessary JSON file changes, and creating a new chain with the modified JSON file as genesis. This procedure is tedious, and could take up to several hours.
Cosmos SDK v0.43 introduces a new way of handling upgrades. When an upgrade happens, instead of starting a new chain, the new binary will read the existing database, and perform in-place modifications of the store. We expect this method to significantly reduce the migration time.
For more information:
- see the [upgrading modules](https://docs.cosmos.network/master/building-modules/upgrade.html) documentation to learn how to modify your module to be able to support in-place store migrations,
- check out how to [set up an upgrade handler](https://docs.cosmos.network/master/core/upgrade.html) that perform in-place store migrations in your `app.go`,
- read [ADR-041](https://github.com/cosmos/cosmos-sdk/blob/master/docs/architecture/adr-041-in-place-store-migrations.md) introducing this feature.
## Protobuf Client-Side Breaking Changes
In this release, we deprecated a couple of fields in our Protobuf definitions. When using these fields, some changes in behavior might occur whether you're hitting an v0.42 or a v0.43 node.
- `cosmos.gov.v1beta1.Vote#option` is deprecated in favor of `cosmos.gov.v1beta1.Vote#options` (with an "s") to support x/gov [split votes](https://github.com/cosmos/cosmos-sdk/blob/master/docs/architecture/adr-037-gov-split-vote.md). There are no breaking changes in `Msg`s, as a new `MsgWeightedVote` has been added to support split votes. However, when querying, the deprecated `option` field is populated only when the underlying vote has one VoteOption with weight 1. For other split votes, the `option` field will be equal to `OptionEmpty`.
- `cosmos.upgrade.v1beta1.Plan#time` is deprecated, because the SDK stops supporting time-based upgrades in favor or height-based upgrades. If an upgrade Plan is created with a non-empty time, the node will error.
- `cosmos.upgrade.v1beta1.Plan#upgraded_client_state` is deprecated as IBC logic has been moved to the IBC repo. If this field is set, the node will error.
The SDK team is planning to document Protobuf change process using an ADR. It will be a guideline for all chain developers, follow [#9477](https://github.com/cosmos/cosmos-sdk/issues/9477) for more info.
