Document Versioning in AceProject: Several Versions of a Document
Versioning
Keep an history of every document's changes. Use alphanumeric version numbers or simulate document approval statuses.
Feature Description
AceProject's versioning feature enables users to keep track of all iterations made to a specific project or task document. All documents uploaded can be given an alphanumeric version number. As a result, a document can have a 1.0, a 1.1, a 1.2 version, or a "Draft", a "Submitted for Approval" and an "Approved" version, for instance. This feature is great for document tracking as it empowers users to get an insight on the evolution of every document.
In addition to the version number, a description can be added and the uploader is mentioned. This also helps manage your documents with great efficiency.
