Guiding Principles:
|
|
|
|
Changelogs are for humans, not machines.
|
|
There should be an entry for every single version.
|
|
The same types of changes should be grouped.
|
|
Versions and sections should be linkable.
|
|
The latest version comes first.
|
|
The release date of each version is displayed.
|
|
Mention whether you follow Semantic Versioning.
|
|
|
|
Usage:
|
|
|
|
Changelog entries are generated by git cliff ref: https://github.com/orhun/git-cliff
|
|
|
|
Each commit should be conventional, the following message groups are supported.
|
|
|
|
* feat: A new feature
|
|
* fix: A bug fix
|
|
* docs: Documentation only changes
|
|
* style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
|
|
* refactor: A code change that neither fixes a bug nor adds a feature
|
|
* perf: A code change that improves performance
|
|
* test: Adding missing tests or correcting existing tests
|
|
* build: Changes that affect the build system or external dependencies (example scopes: go, npm)
|
|
* ci: Changes to our CI configuration files and scripts (example scopes: GH Actions)
|
|
* chore: Other changes that don't modify src or test files
|
|
* revert: Reverts a previous commit
|
|
|
|
When a change is made that affects the API or state machine, the commit message prefix should be suffixed with `!`.

## [math/v1.2.0](https://github.com/cosmos/cosmos-sdk/releases/tag/math/v1.2.0) - 2023-11-07
|
|
|
|
### Features
|
|
|
|
* [#18247](https://github.com/cosmos/cosmos-sdk/pull/18247) Add mutative api for `Uint.BigInt()`.

|
|
* [#18030](https://github.com/cosmos/cosmos-sdk/pull/18030) Add mutative api for `NewIntFromBigInt`.
|
|
|
|
### Bug Fixes
|
|
|
|
* [#18228](https://github.com/cosmos/cosmos-sdk/pull/18228) Fix panic when calling `BigInt()` on an uninitialized `Uint`.
|
|
* [#18214](https://github.com/cosmos/cosmos-sdk/pull/18214) Ensure that modifying the argument to `NewUIntFromBigInt` doesn't mutate the returned value.
|
|
* [#18211](https://github.com/cosmos/cosmos-sdk/pull/18211) RelativePow now returns 1 when 0^0, before it was returning the scale factor.
|
|
* [#17725](https://github.com/cosmos/cosmos-sdk/pull/17725) Fix state break in ApproxRoot. This has been present since math/v1.0.1. It changed the rounding behavior at precision end in an intermediary division from banker's to truncation. The truncation occurs from binary right shift in the case of square roots. The change is now reverted back to banker's rounding universally for any root.
