# Changelog
All notable changes and migrations to pallet-staking will be documented in this file.
The format is loosely based
on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/). We maintain a
single integer version number for staking pallet to keep track of all storage
migrations.
## [v14]
### Added
- New item `ErasStakersPaged` that keeps up to `MaxExposurePageSize`
individual nominator exposures by era, validator and page.
- New item `ErasStakersOverview` complementary to `ErasStakersPaged` which keeps
state of own and total stake of the validator across pages.
- New item `ClaimedRewards` to support paged rewards payout.
### Deprecated
- `ErasStakers` and `ErasStakersClipped` is deprecated, will not be used any longer for the exposures of the new era
post v14 and can be removed after 84 eras once all the exposures are stale.
- Field `claimed_rewards` in item `Ledger` is renamed
to `legacy_claimed_rewards` and can be removed after 84 eras.
