+Adwarp can now build LinkedIn matched audiences straight from HubSpot, the same way it already does from Salesforce.
+
+### HubSpot audiences
+
+- New MCP tool `audience_from_hubspot` and CLI command `adwarp audience from-hubspot`. Point it at a HubSpot list or a set of property filters, pick contacts or companies, and it uploads the result as a LinkedIn matched audience.
+- It reads HubSpot with a private app token you create in your own HubSpot account, with read-only scopes for contacts, companies and lists. Put the token in `~/.adwarp/hubspot.json` or `ADWARP_HUBSPOT_TOKEN`.
+- Contacts go through the same cleaning as CSV uploads, and only SHA-256 hashes of the emails leave your machine. `--dry-run` shows the counts and a masked sample, and uploads nothing.
+- It runs locally only. The hosted endpoint doesn't register it.
+- Setup and examples: https://adwarp.dev/docs/hubspot
+
+### Docs and the hosted endpoint
+
+- The docs now live at https://adwarp.dev/docs, with new setup pages for Claude Code, Claude Desktop, Codex, Cursor and the CLI, and a LinkedIn Ads overview.
+- `docs/tools.json` now marks the tools that need your machine (CSV and Salesforce uploads, HubSpot audiences and the change journal) as not hosted.
+- The hosted app at mcp.adwarp.dev is now just the MCP endpoint. Its old pages redirect to adwarp.dev, and `https://mcp.adwarp.dev/api/mcp` works as before.
+
+### Other changes
+
+- Company list uploads now check LinkedIn's 300,000 row limit, as contact lists already did.
+- `docs/tools.json` lists 37 tools: 28 for LinkedIn Ads and 9 for Google Ads.
