Change history

This timeline summarizes changes identified in SO’s GitHub commit history, including updates to labels, definitions, parent terms, synonyms, subsets, and obsoletion status. It is a best-effort reconstruction and may not include every change to a term. Since only history from GitHub is included at the moment, any term added before the migration from SVN to Git will show as being created in 2016. This will be addressed once SVN history is incorporated.
