What is document version control?
Document version control is keeping track of successive revisions of a document so everyone works from the current version and earlier ones can still be identified and referred back to.
Version control stops the 'final_v3_really_final' problem. As a document is revised, each version is tracked so it is always clear which is current, what changed, and when. Without it, people comment on stale drafts, act on superseded numbers, and lose track of which copy was the one actually agreed.
In confidential sharing this is not just tidiness - it is evidence. If a signed contract or a disclosed financial statement is later disputed, you may need to show precisely which version a party saw or signed. That requires the current version to be unambiguous and the signed version to be pinned beyond doubt.
Version control pairs naturally with an audit trail: one tells you which version of the truth was in force, the other tells you who saw or signed it and when.
In 99 Data Rooms
How it works here.
In 99 Data Rooms you share the current document as a tracked link, so recipients always reach the version you have published rather than an old attachment sitting in an inbox. When a document is signed, the e-signature audit certificate pins a SHA-256 fingerprint of the exact signed file, so the signed version is tamper-evident and cannot be quietly swapped.
Common questions
Document version control, in short.
Why does version control matter for signed documents?
Because a dispute can turn on which version was signed. 99 Data Rooms records a SHA-256 fingerprint of the signed file in its audit certificate, so the exact signed version is provable and any later change is detectable.
How is this different from just saving files with version numbers?
Manual file naming relies on discipline and breaks down across a team. Sharing through a tracked link means recipients always open the version you published, and the signature fingerprint removes any doubt about which file was executed.
