This one is for everyone who writes in British or Australian English (and anyone who simply prefers grey over gray): OpusWriter now writes in your English.

Choose your English: American, British, or Australian

Head to Workspace Settings and pick your spelling under the new Language & Region section. Spell-check follows your choice across the whole app, so colour, organise, and travelled are right at home in British and Australian English, while color, organize, and traveled stay correct in American.

Corrections that match your English

When a word gets flagged, the suggestion that fits your dialect now leads the list. Flag gray in British English and grey is the first correction offered, instead of buried at the bottom.

Your exports speak it too

Whatever English you choose travels into your finished book. Word, EPUB, PDF, and web exports all carry the matching language, so e-readers, Word's proofing, and the web all know which English your book is written in.
