| ## Overview | ||
|
|
||
| Pactus Blockchain [Version 1.6.0 (Mumbai)](https://github.com/pactus-project/pactus/releases/tag/v1.6.0) | ||
| is now available for download. | ||
| This release includes the following applications: | ||
|
|
||
| - [Pactus GUI](https://docs.pactus.org/get-started/pactus-gui/): | ||
| The graphical user interface (GUI) for the Pactus node that is suitable | ||
| for both beginners and experienced users. | ||
|
|
||
| - [Pactus Daemon](https://docs.pactus.org/get-started/pactus-daemon/): | ||
| The command-line interface (CLI) for the Pactus node that is suitable for experienced users. | ||
|
|
||
| - [Pactus Shell](https://docs.pactus.org/tutorials/pactus-shell/): | ||
| The command-line tool that allows users to interact with a Pactus node. | ||
|
|
||
| - [Pactus Wallet](https://docs.pactus.org/tutorials/pactus-wallet/): | ||
| The wallet software that allows users to manage their wallet and send transactions | ||
| without the need to sync the entire blockchain. | ||
|
|
||
| ## Highlights | ||
|
|
||
| ### Gas-Free Transactions | ||
|
|
||
| The Mumbai version introduces zero-free transactions. | ||
| The fees for these transactions are calculated based on | ||
| the consumption-based fee model discussed in [PIP-31](https://pips.pactus.org/PIPs/pip-31). | ||
| To send transactions with no fees, please upgrade your node to this version. | ||
| However, there are some limitations for sending zero-free transactions: | ||
|
|
||
| - Each address can send about two free transactions daily, | ||
| - The confirmation time for zero-fee transactions is longer. | ||
|
|
||
| The fee configuration in Pactus is not deterministic, | ||
| as each validator sets its own preferences to collect transactions with adjusted values. | ||
| We encourage validators with sufficient resources to | ||
| change their configurations to accept zero-fee transactions. | ||
| The suggested values for supporting zero-free transactions are: | ||
|
|
||
| ```toml | ||
| [tx_pool.fee] | ||
| fixed_fee = 0 # PAC | ||
| daily_limit = 360 # Bytes | ||
| unit_price = 0.000005 # PAC | ||
| ``` | ||
|
|
||
| ### Single Reward Address | ||
|
|
||
| Starting with the Mumbai version, only one reward address will be created for all validator addresses. | ||
| This is a behavioral change in how nodes start. | ||
| If a reward address is not set in the config, the application will attempt to | ||
| retrieve the first account address from the wallet and use it as the reward address. | ||
|
|
||
| ### Docker Multi-Platform Support | ||
|
|
||
| Pactus [Docker](https://hub.docker.com/r/pactus/pactus/tags) | ||
| now supports multiple platforms, including Linux-amd, Linux-arm64, and others. | ||
| Users who need to run Pactus on different platforms can now use | ||
| the Pactus Docker images for their specific environments | ||
|
|
||

| page and join the Mainnet. | ||
|
|
||
| ## How to Upgrade | ||

| Then uninstall the previous version and install the newer version. | ||
