GridPath 0.1.9

Adds MCP Registry metadata. No functional changes since 0.1.8.

GridPath 0.1.8

Much faster on large workbooks: on a 1.4 MB, 55,000-formula model, tool time for an edit drops from about 16 s to about 6 s. Saving no longer reloads the file, and listing named ranges is no longer quadratic.

GridPath 0.0.1

GridPath desktop app: an AI agent for Excel that edits the workbooks you already have and gives them back intact. Surgical .xlsx patching in Rust, accept/reject review of every change, bring your own Claude or ChatGPT subscription.

These are the same builds served from gridpath.dev.
