# v1.13.0-beta.0
## Downloads for v1.13.0-beta.0

Download v1.13.0-beta.0 in the [v1.13.0-beta.0 release page](https://github.com/karmada-io/karmada/releases/tag/v1.13.0-beta.0).

## Changelog since v1.13.0-alpha.2

## Urgent Update Notes
- The Karmada Lua interpreter will no longer support the Lua functions `string.rep` and `string.gsub`. Typically, these functions are not 
frequently used in custom Karmada resource interpreters. They are disabled due to potential security risks. Before upgrading, please review 
your Lua scripts to verify whether these functions are being used. If they are, please replace them with alternative implementations.

## Changes by Kind

### API Changes
- `API Change`: Introduced `PriorityClassName` in `Karmada` API which will be used to specify the priority class name of that component. ([#6068](https://github.com/karmada-io/karmada/pull/6068), @jabellard)

### Features & Enhancements
- `karmadactl`: standardize the naming of karmada config in karmadactl installation method. ([#5797](https://github.com/karmada-io/karmada/pull/5797), @chaosi-zju)

### Deprecation
None.

### Bug Fixes
- `karmada-controller-manager`: Fixed an issue that the scheduling suspension on ResourceBinding might be mistakenly overwritten. ([#6062](https://github.com/karmada-io/karmada/pull/6062), @Monokaix)
- `karmada-search`: Fixed the issue that namespaces in different ResourceRegistry might be overwritten. ([#6065](https://github.com/karmada-io/karmada/pull/6065), @JimDevil)

### Security
- `karmada-controller-manager`: For security reasons, we made the following changes to restrict the string library functions used when users customize the Karmada Lua interpreter. ([#6087](https://github.com/karmada-io/karmada/pull/6087), @zhzhuang-zju)
  1. do not allow users to use string.gsub and string.rep when interpreting resources with lua scripts, which may be used to create overly long strings.
  2. limit the length of the string type parameters of the function to 1000,000.
  3. add timeout checks to the internal for loops within the functions.
