Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

v15.2.0

Security

  • Prevents a deadlock that new smart contracts could cause due to bugs in the SDK

Bug fixes

  • Makes historic queries use the correct block timestamp
  • Fixes a bug where certain governance events weren't emitted
  • Adds mempool protection for Barberry bug
  • Various export genesis bug fixes

v15.1.2

Security

Misc Improvements

  • #5129 Relax twap record validation in init genesis to allow one of the spot prices to be non-zero when twap error is observed.

  • #5134 Update sdk fork with the change for correct block time in historical queries (#5134)

v15.1.1

Same changes included in v15.1.2 but redacted as tagged commit was not part of v15.x branch.

v15.1.0

Security

Features

Misc Improvements

  • #4582 Consistently generate build tags metadata, to return a comma-separated list without stray quotes. This affects the output from version CLI subcommand and server info API calls.

v15.0.0

This release containts the following new modules:

  • ProtoRev module (x/protorev). This module captures MEV via in-protocol cyclic arbitrage and distributes the revenue back to the protocol based on governance. Developed by the Skip team.
  • Validator Set Preference module (x/valset-pref). This module gives users the ability to delegate to multiple validators according to their preference list.
  • Pool Manager module (x/poolmanager). This module manages the infrastructure around pool creation and swaps. It serves as a unified entrypoint for any swap related message or query. This module is extracted from the pre-existing x/gamm. It is the first milestone on the path towards delivering concentrated liquidity.

v13.1.2

Osmosis v13.1.2 is a minor patch release that includes several bug fixes and updates.

The main bug fix in this release is for the state export feature, which was not working properly in previous versions. This issue has now been resolved, and state export should work as expected in v13.1.2.

Additionally, the swagger files for v13 have been updated to improve compatibility and ensure that all API endpoints are properly documented.

Misc Improvements

v13.0.0

This release includes stableswap, and expands the IBC safety & composability functionality of Osmosis. The primary features are:

  • Gamm:
    • Introduction of the stableswap pool type
    • Multi-hop swapfee reduction
    • Filtered queries to help front-ends
    • Adding a spot price v2 query
      • spotprice v1beta1 had baseassetdenom and quoteassetdenom backwards.
      • All contracts and integrators should switch to the v2 query from now on.
    • Adding more queries for contract developers
    • Force unpooling is now enableable by governance
  • IBC features
    • Upgrade to IBC v3.4.0

  • #3313 Upgrade to IBC v3.4.0, allowing for IBC transfers with metadata.
  • #3335 Add v2 spot price queries
    • The v1beta1 queries actually have base asset and quote asset reversed, so you were always getting 1/correct spot price. People fixed this by reordering the arguments.
    • This PR adds v2 queries for doing the correct thing, and giving people time to migrate from v1beta1 queries to v2.
    • It also changes cosmwasm to only allow the v2 queries, as no contracts on Osmosis mainnet uses the v1beta1 queries.

Bug fixes

v8.0.0 - Emergency proposals upgrade

This upgrade is a patch that must be hard forked in, as on-chain governance of Osmosis approved proposal 227 and proposal 228.

This upgrade includes:

  • Adding height-gated AnteHandler message filter to filter unpooling tx pre-upgrade.
  • At block height 4402000 accelerates prop 225, which in turn moves incentives from certain pools according to props 222-224
  • Adds a msg allowing unpooling of UST pools.
    • This procedure is initiated by whitelisting pools 560, 562, 567, 578, 592, 610, 612, 615, 642, 679, 580, 635.
    • Unpooling allows exiting whitelisted pools directly, finish unbonding duration with the exited tokens instead of having to wait unbonding duration to swap LP shares back to collaterals.
    • This procedure also includes locks that were already unbonding pre-upgrade and locks that were superfluid delegated.

Every node should upgrade their software version to v8.0.0 before the upgrade block height 4402000. If you use cosmovisor, simply swap out the binary at upgrades/v7/bin to be v8.0.0, and restart the node. Do check cosmovisor version returns v8.0.0

v7.0.2 - Carbon

This release fixes an instance of undefined behaviour present in v7.0.0. Parts of the code use a function called ApplyFuncIfNoErr whose purpose is to catch errors, and if found undo state updates during its execution. It is intended to also catch panics and undo the problematic code's execution. Right now a panic in this code block would halt the node, as it would not know how to proceed. (But no state change would be committed)

v7.0.0 - Carbon

The Osmosis Carbon Release! The changes are primarily

The large features include:

  • Superfluid Staking - Allowing LP shares be staked to help secure the network

v6.2.0

SDK fork updates

  • sdk-#58 Fix a bug where recheck would not remove txs with invalid sequence numbers

Minor improvements & Bug Fixes

  • #765 Fix a bug in Makefile regarding the location of localtestnet docker image.

v6.1.0

Features

  • Update to Tendermint v0.34.15
  • Increase p2p timeouts to alleviate p2p network breaking at epoch
  • #741 Allow node operators to set a second min gas price for arbitrage txs.
  • #623 Use gosec for staticly linting for common non-determinism issues in SDK applications.

Minor improvements & Bug Fixes

  • #722 reuse code for parsing integer slices from string
  • #704 fix rocksdb
  • #666 Fix the --log-level and --log-format commands on osmosisd start
  • #655 Make the default genesis for pool-incentives work by default
  • 97ac2a8 Fix InitGenesis bug for gauges

SDK fork updates

  • sdk-#52 Fix inconsistencies in default pruning config, and change defaults. Fix pruning=everything defaults.
    • previously default was actually keeping 3 weeks of state, and every 100th state. (Not that far off from archive nodes)
    • pruning=default now changed to 1 week of state (100k blocks), and keep-every=0. (So a constant number of states stored)
    • pruning=everything now stores the last 10 states, to avoid db corruption errors plaguing everyone who used it. This isn't a significant change, because the pruning interval was anyways 10 blocks, so your node had to store 10 blocks of state anyway.
  • sdk-#51 Add hooks for superfluid staking
  • sdk-#50 Make it possible to better permission the bank keeper's minting ability

v6.0.0

This upgrade fixes a bug in the v5.0.0 upgrade's app.go, which prevents new IBC channels from being created. This binary is compatible with v5.0.0 until block height 2464000, estimated to be at 4PM UTC Monday December 20th.

  • Patch - Revert back to passing in the correct staking keeper into the IBC keeper constructor.
  • Height gating change - Height gate the change in IBC, to make the v6.0.0 binary compatible until upgrade height.
