Vedaksha v7.2.0: what changes for you
Shadbala's positional strength was one sub-component of five, and every response said otherwise — if you consume compute_shadbala, your numbers move. Ketu is a first-class body sharing Rahu's frame. Two arguments that were accepted and ignored are now validated, so a call that used to pass can now fail.

Vedaksha v5.0.0: three defects that moved every chart
Sidereal time was built on the wrong clock, moving every ascendant and cusp by 5.18' to 30.23'. Sidereal charts placed rotated planets against unrotated cusps: 77.4% landed in the wrong bhava. The vara was a UT weekday. Also 26.2x faster on panchanga; ephemeris residuals unchanged.

Vedaksha v2.2.0: Gochara, the way it should be designed
Gochara (transit interpretation) ships in v2.2.0. The API follows BPHS Ch.29 geometry strictly; vedha_candidates returns all geometric candidates, not one. MCP tool count: 11 → 12.

Vedaksha v2.1.0: Combustion, Ishta/Kashta, Ashtakavarga, Karakas
Four new Vedic primitives in v2.1.0. Per-planet combustion orbs from BPHS Ch.7, Ishta/Kashta Phala via the Rasmi formula, Bhinna Ashtakavarga tables, and Jaimini Chara Karaka assignments.

KundaliMCP: the first product built on Vedaksha
From engine to product. KundaliMCP is the first deployed application built on Vedaksha, an agentic-AI-native Jyotish API. What the library provided, what the product layer added.

Why Charts Should Be Graphs
Astrological charts are property graphs. The case for 9 node types and 12 edge types, and why Cypher, SurrealQL, JSON-LD, and embedding-text emitters make AI agents useful.
