Every version, and what it changed for you.

One command per subject, instead of two that share one.

Before you upgrade — Nothing to change, and no reindex. Every command you already type still works — the older spellings parse exactly as before and print the one line naming what to type instead, so scripts and muscle memory keep working while you move over.

• Newchi status answers the question you actually have after chi init: is Archis ready in this repository, what does the index hold, and how far has it drifted from what is on disk. That last part is what chi overview could not tell you — counts on their own cannot say whether they are current, and the number of files waiting to be picked up can. It replaces chi overview and takes over what chi support did, under --languages. chi status and chi doctor stay deliberately separate: status is about the index, doctor is about the installation.
• ImprovedTwenty-five commands became eighteen, and nothing you could do before is gone. Five pairs were one subject split in two, and the split was yours to solve: chi index and chi reindex asked you to decide whether you needed a full build or an incremental one, and chi symbol and chi refs made "what does this symbol reach" a different word from "what is this symbol". chi index now decides for itself — a repository with no index is built whole, one that has an index has only its changed files recompiled and its deleted ones forgotten, and chi index src/router.ts refreshes that one file. chi symbol answers both directions of the call graph with --refs, one each with --calls and --called-by, and the transitive reach with --impact. chi auth is the one noun for the account, with login, logout, status and refresh under it; chi keys stays separate on purpose, because local encryption is a different job from signing in. And chi tools gathers the advanced surface that was three separate commands.
• ImprovedThe download is smaller: 62.07 MB on 0.28.0, 59.05 MB here, for the same product.
• Fixedchi index finished saying it in English. The progress display, the per-file counts and the notes and warnings it ends with were the last Spanish left in the CLI, on a command almost everybody runs first. They also group thousands the way the rest of the output does, and say "1 symbol" rather than "1 symbols".
