We are happy to announce the new version of fuel-core 0.28.0. With this release, the following changes are introduced for the users and the network.

For the network:

- Removed cases when the node could halt during synchronization.
- Optimized how VM memory is used and passed between different node layers. The change - allows charging the user less for VM initialization and a fair charge for the user for allocation operations.
- All opcodes became cheaper. More information about price changes [here](https://github.com/FuelLabs/fuel-core/pull/1934/files#diff-a12c714e4dbb6f375ee2aef053e8d36ba844e1baf2439e07f407657cd96e3904).

For the user:

- Speedup synchronization with the network for the first 1.5M blocks.
- Fixed problems with the reconnection mechanism.
- Added ability to specify the gas price during dry-running transactions.

You can find the release notes for the SDK [here](https://github.com/FuelLabs/fuels-rs/releases/tag/v0.64.0).

You must upgrade your SDKs to use the new version of the fuel-core

Thank you for the information. However, when I try to update fuel-core to version 0.28.0, it says that the latest version is fuel-core 0.26.0. I am following the documentation with the codes I am using below.

```auto
fuelup self update
Already up to date (fuelup v0.25.1)

An update to the previous announcement for the fuel core `0.28.0`. To use the latest network, you must upgrade the Rust SDK to version `0.64.0`.

To continue working, you must upgrade your SDK to the above-mentioned versions before Saturday; otherwise, the older SDK versions will stop working.
