Dyalog Version 18.0 Issue 2 is now available under Microsoft Windows, Linux (including the Raspberry Pi), Apple macOS and AIX. You can now also download 18.0-based Docker containers. Issue 2 contains fixes for a small number of critical bugs, as well as some enhancements.
Dyalog strongly recommends that you download these new images and install them (in the case of Windows, you must uninstall your current 18.0 first and reboot).
More information and details of how to download the software can be found in the news article about 18.0 Issue 2 on https://www.dyalog.com/news/141/420/Introducing-Dyalog-Version-18-0-Issue-2.htm.
