# Salt 3004 Release Notes - Codename Silicon

## New Features

### Transactional System Support (MicroOS)

A transactional system, like `MicroOS`, can present some challenges when the user decided to manage it via Salt.

MicroOS provide a read-only rootfs and a tool, `transactional-update`, that takes care of the management of the system (updating, upgrading, installation or reboot, among others) in an atomic way.

Atomicity is the main feature of MicroOS, and to guarantee this property, this model leverages `snapper`, `zypper`, `btrfs` and `overlayfs` to create snapshots that will be updated independently of the currently running system, and that are activated after the reboot. This implies, for example, that some changes made on the system are not visible until the next reboot, as those changes are living in a different snapshot of the file system.

Salt 3004 (Silicon) support this type of system via two new modules (`transactional_update` and `rebootmgr`) and a new executor (`transactional_update`).

The new modules will provide all the low level API for interacting with transactional systems, like defining a mantenance window where the system is free to reboot and activate the new state, or install new software in a new transaction. It will also provide hight level of abstractions that will allows us to execute Salt module functions or applying states inside new transactions.

The execution module will help us to treat the transactional system transparently (like the traditional ones), using a mechanism that will delegate some Salt modules execution into the new `transactional_update` module.

## Removed

- Removed the deprecated glance state and execution module in favor of the glance_image state module and the glanceng execution module. (#59079)
