v1.6.0 — opt-in comments, feature-request bounds, faster paging

Full details are in the changelog.

limit and sort on get_feature_requests. Keep the top N per portal by votes or recency. Comments are fetched only for what's kept.

include_comments on the analysis tools (off by default). It adds customer comment text to theme matching and quotes; admin replies and commenter names are dropped. The gain is modest: a few extra matches per theme. On large portals a call can take close to a minute because of ProductLift's 120-a-minute rate limit.

Install from source; see the README quick start.
