v0.6.8

• New article, How the Weather Has Changed in Three Northern BC Watersheds: a short, plain-language story of the Bulkley, Nechako and Parsnip watershed groups against 1951–1980, written for readers with no climate background, with the upper and lower Bulkley compared and a table of what the changes mean for streams and fish. Every number on the page is computed from bundled data, and the data script stops a regen that would make one of its sentences false. (#137, #141)
• cd_compare() now describes its default reference window, 1951–1980, as the pre-warming reference (the GISS base period) rather than a WMO-style standard normal. Behaviour is unchanged.
