### NEW-0725-1: deploy: optional changelog field

[POST /v1/infra/servers/:id/deploy](/docs/infra/deploy/deploy) accepts a new optional `changelog` field — plain text up to 2000 characters describing what changed in this version. When a new app version ships, the text is posted to subscribers in the app's Bitrix24 messenger channel feed; if the field is omitted, only the version number is posted. The field works in both JSON and multipart deploy modes. Existing deploy calls keep working unchanged.
