| # Upgrading Quasar to v3 | ||
|
|
||
| This guide provides instructions for upgrading to specific versions of Quasar. | ||
|
|
||
| ## [v3.x](https://github.com/quasar-finance/quasar/releases/tag/v3.0.0) | ||
|
|
||
| ### `Binary Name Change` | ||
| - This version contains binary name change from `quasarnoded` to `quasard` which requires changes in Cosmovisor settings. | ||
|
|
||
| ### `Feemarket Module Addition and Relayer Config Changes` | ||
|
|
||
| - It contains Feemarket module addition with min gas fee. | ||
| This needs changes on relayer `gas-prices` to be set equal to params set in feemarket module. | ||
|
|
||
| - Feemarket brings in variable gas depending on past few block usage which in turn will affect the `gas-adjustment` parameter as well. | ||
| It should ideally be set to 2 or above. | ||
|
|
||
| ### Packages | ||
|
|
||
| New modules added : | ||
| - PFM v8 | ||
| - Ibc-hooks v8 | ||
| - Rate-limiting v8 | ||
| - Feemarket v1 | ||
|
|
||
| Updates : | ||
| - Wasmd v0.45 to v0.51 | ||
| - Wasmvm from v1 to v2 | ||
| - Cosmos-SDK from v47.12 to v50.9 | ||
| - Ibc-go v7 to ibc-go v8 | ||
| - Contains updates of Async ICQ, wasm light clients and capability module. | ||
|
|
||
| Upgrade removes old unused modules : | ||
| - `qVesting` | ||
| - `qOracle` | ||
| - `qTransfer` | ||
