0g-chain/CHANGELOG.md

<!--
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:

Change log entries are to be added to the Unreleased section under the
appropriate stanza (see below). Each entry should ideally include a tag and
the Github issue reference in the following format:

* (<tag>) \#<issue-number> message

The issue numbers will later be link-ified during the release process so you do
not have to worry about including a link manually, but you can if you wish.

Types of changes (Stanzas):

"Features" for new features.
"Improvements" for changes in existing functionality.
"Deprecated" for soon-to-be removed features.
"Bug Fixes" for any bug fixes.
"Client Breaking" for breaking CLI commands and REST routes.
"State Machine Breaking" for breaking the AppState

## [v0.8.1](https://github.com/Kava-Labs/kava/releases/tag/v0.8.1) kava-3 Patch Release

This version mitigates a memory leak in tendermint that was found prior to launching kava-3. It is fully compatible with v0.8.0 and is intended to replace that version as the canonical software version for upgrading the Kava mainnet from kava-2 to kava-3. Note that there are no breaking changes between the versions, but a safety check was added to this version to prevent starting the node with an unsafe configuration.

### Bugfix

The default tendermint pruning strategy, `pruning="syncable"` is currently unsafe due to a [memory leak](https://github.com/tendermint/iavl/issues/256) that can cause irrecoverable data loss. This patch release prevents `kvd` from being started with the `pruning="syncable"` configuration. Until a patch for tendermint is released, the ONLY pruning strategies that are safe to run are `everything` (an archival node) or `nothing` (only the most recent state is kept). It is strongly recommended that validators use `pruning="nothing"` for kava-3. It is expected that a patch to tendermint will be released in a non-breaking manner and that nodes will be able to update seamlessly after the launch of kava-3.

The steps for upgrading to kava-3 can be found [here](https://github.com/Kava-Labs/kava/blob/master/contrib/kava-3/migration.md). Please note the additional section on [pruning](https://github.com/Kava-Labs/kava/blob/master/contrib/kava-3/migration.md#Pruning).

## [v0.8.0](https://github.com/Kava-Labs/kava/releases/tag/v0.8.0) kava-3 Release

This version is intended to be the canonical software version for upgrading the Kava mainnet from kava-2 to kava-3. As a result, no subsequent versions of Kava will be released until kava-3 launches unless necessary due to critical state-machine faults that require a new version to launch successfully.

### Migration

The steps for upgrading to kava-3 can be found [here](https://github.com/Kava-Labs/kava/blob/master/contrib/kava-3/migration.md)

### Features

This is the first release that includes all the modules which comprise the [CDP system](https://docs.kava.io/).

### State Machine Breaking Changes

(sdk) Update Cosmos-SDK version to v0.38.4. To review cosmos-sdk changes, see the [changelog](https://github.com/cosmos/cosmos-sdk/blob/v0.38.4/CHANGELOG.md).


## [v0.3.5](https://github.com/Kava-Labs/kava/releases/tag/v0.3.5)

Bump tendermint version to 0.32.10 to address [cosmos security advisory Lavender](https://forum.cosmos.network/t/cosmos-mainnet-security-advisory-lavender/3511)

## [v0.3.2](https://github.com/Kava-Labs/kava/releases/tag/v0.3.2)

[\#364](https://github.com/Kava-Labs/kava/pulls/364)  Use new BIP44 coin type in the CLI, retain support for the old one through a flag.

## [v0.3.1](https://github.com/Kava-Labs/kava/releases/tag/v0.3.1)

[\#266](https://github.com/Kava-Labs/kava/pulls/266) Bump tendermint version to 0.32.7 to address cosmos security advisory [Periwinkle](https://forum.cosmos.network/t/cosmos-mainnet-security-advisory-periwinkle/2911)

## [v0.3.0](https://github.com/Kava-Labs/kava/releases/tag/v0.3.0)

### Features

[\#253](https://github.com/Kava-Labs/kava/pulls/253) Add a new validator vesting account type, which releases coins on a periodic vesting schedule based on if a specific validator signed sufficient pre-commits. If the validator didn't sign enough pre-commits, the vesting coins are burned or sent to a return address.
