# Changelog
## 0.26.0
BREAKING CHANGES
* Gaia
* [gaiad init] [\#2602](https://github.com/cosmos/cosmos-sdk/issues/2602) New genesis workflow
* SDK
* [simulation] [\#2665](https://github.com/cosmos/cosmos-sdk/issues/2665) only argument to simulation.Invariant is now app
* Tendermint
* Upgrade to version 0.26.0
FEATURES
* Gaia CLI (`gaiacli`)
* [cli] [\#2569](https://github.com/cosmos/cosmos-sdk/pull/2569) Add commands to query validator unbondings and redelegations
* [cli] [\#2569](https://github.com/cosmos/cosmos-sdk/pull/2569) Add commands to query validator unbondings and redelegations
* [cli] [\#2524](https://github.com/cosmos/cosmos-sdk/issues/2524) Add support offline mode to `gaiacli tx sign`. Lookups are not performed if the flag `--offline` is on.
* [cli] [\#2558](https://github.com/cosmos/cosmos-sdk/issues/2558) Rename --print-sigs to --validate-signatures. It now performs a complete set of sanity checks and reports to the user. Also added --print-signature-only to print the signature only, not the whole transaction.
* [cli] [\#2704](https://github.com/cosmos/cosmos-sdk/pull/2704) New add-genesis-account convenience command to populate genesis.json with genesis accounts.
* SDK
* [\#1336](https://github.com/cosmos/cosmos-sdk/issues/1336) Mechanism for SDK Users to configure their own Bech32 prefixes instead of using the default cosmos prefixes.
IMPROVEMENTS
* Gaia
* [\#2637](https://github.com/cosmos/cosmos-sdk/issues/2637) [x/gov] Switched inactive and active proposal queues to an iterator based queue
* SDK
* [\#2573](https://github.com/cosmos/cosmos-sdk/issues/2573) [x/distribution] add accum invariance
* [\#2556](https://github.com/cosmos/cosmos-sdk/issues/2556) [x/mock/simulation] Fix debugging output
* [\#2396](https://github.com/cosmos/cosmos-sdk/issues/2396) [x/mock/simulation] Change parameters to get more slashes
* [\#2617](https://github.com/cosmos/cosmos-sdk/issues/2617) [x/mock/simulation] Randomize all genesis parameters
* [\#2669](https://github.com/cosmos/cosmos-sdk/issues/2669) [x/stake] Added invarant check to make sure validator's power aligns with its spot in the power store.
* [\#1924](https://github.com/cosmos/cosmos-sdk/issues/1924) [x/mock/simulation] Use a transition matrix for block size
* [\#2660](https://github.com/cosmos/cosmos-sdk/issues/2660) [x/mock/simulation] Staking transactions get tested far more frequently
* [\#2610](https://github.com/cosmos/cosmos-sdk/issues/2610) [x/stake] Block redelegation to and from the same validator
* [\#2652](https://github.com/cosmos/cosmos-sdk/issues/2652) [x/auth] Add benchmark for get and set account
* [\#2685](https://github.com/cosmos/cosmos-sdk/issues/2685) [store] Add general merkle absence proof (also for empty substores)
* [\#2708](https://github.com/cosmos/cosmos-sdk/issues/2708) [store] Disallow setting nil values
BUG FIXES
* Gaia
* [\#2670](https://github.com/cosmos/cosmos-sdk/issues/2670) [x/stake] fixed incorrect `IterateBondedValidators` and split into two functions: `IterateBondedValidators` and `IterateLastBlockConsValidators`
* [\#2691](https://github.com/cosmos/cosmos-sdk/issues/2691) Fix local testnet creation by using a single canonical genesis time
* [\#2648](https://github.com/cosmos/cosmos-sdk/issues/2648) [gaiad] Fix `gaiad export` / `gaiad import` consistency, test in CI
* SDK
* [\#2625](https://github.com/cosmos/cosmos-sdk/issues/2625) [x/gov] fix AppendTag function usage error
* [\#2677](https://github.com/cosmos/cosmos-sdk/issues/2677) [x/stake, x/distribution] various staking/distribution fixes as found by the simulator
* [\#2674](https://github.com/cosmos/cosmos-sdk/issues/2674) [types] Fix coin.IsLT() impl, coins.IsLT() impl, and renamed coins.Is\* to coins.IsAll\* (see [\#2686](https://github.com/cosmos/cosmos-sdk/issues/2686))
* [\#2711](https://github.com/cosmos/cosmos-sdk/issues/2711) [x/stake] Add commission data to `MsgCreateValidator` signature bytes.
* Temporarily disable insecure mode for Gaia Lite
