Hello everyone, We are proud to announce the release of two new extra add-ons which contribute additional rules for the *Oxygen Terminology Checker add-on*! *Important: *The free Oxygen Terminology Checker add-on must be installed in order for these two add-ons to work. First, we have the experimental*ASD Simplified Technical English Specification (ASD-STE100) Rules add-on* that contributes ASD Simplified Technical English Specification rules to the Terminology Checker. It contains technical rules based on ASD-STE100 (http://www.asd-ste100.org), but/note that these rules are not endorsed by ASD-STE100/. Up next, we bring you the *MS Writing Style Guide Vale Rules add-on* that contributes a set of rules based on the Microsoft Writing Style Guide to the Terminology Checker. It contains a Vale-compatible (https://github.com/errata-ai/vale) implementation of the MS Writing Style Guide (https://learn.microsoft.com/en-us/style-guide/welcome) as provided by the errata-ai open-source project (https://github.com/errata-ai/Microsoft). /Note that this project is neither maintained nor endorsed by Microsoft or Vale/.
