# Linux Versions and Updates
> [HTML Version](linuxversionsupdates.htm)
As you know, Linux comes in a variety of flavors/brands/models, and each of those change over time, resulting in multiple versions being out in the world and possibly needing to host A-Shell. The material here is NOT intended to be a catalog of those models and versions, but rather a simple listing of the ways in which A-Shell has adapted to the ever-changing Linux environment. Whenever there is a relevant update to A-Shell made because of or in response to a new version of Linux, an update note will be posted here.
| **A-Shell Version** | **Date** | **Description** |
|------|------|------|
| 1751.5.1 | Nov 2023 | Debian 12 ("Bookworm") version beta release. The Ubuntu 22 and Debian 12 executables are cross-compatible, but the Debian 12 uses a newer version of GCC (12 vs 11) and uses separate package repositories. |
| 1740.1.1 | Sept 2023 | 64 bit executables released for Ubuntu 22 and CentOS Stream 8 platforms. |
| 1674.0 | June 2020 | Initial release of A-Shell for RHEL8/CentOS8. |
| 1600.0 | May 2017 | Linux: Begin internal changes to support 64 bit executable. The ashell executable is usable, but lacks several features, including support for collections. It does however support MSODBC/Linux for connecting to SQL Server, which is only available in 64 bit version. |
