# Versions, history and removed entries

## Versions

A version is the whole entry as it was saved: title, text, question variants,
branches and services. A new version appears when an entry is written, changed,
removed or brought back. Saving with nothing changed makes no version. Old
versions are not overwritten.

## History

**What happened to it** on an entry shows the versions, newest first. Each line
says what happened (Written, Changed, Removed, Brought back), who, when and the
version number.

- When the writer and the approver are different people, the line says
  "{writer}, approved by {approver}".
- A version that came from a suggestion says "Suggested by {writer}, approved
  by {approver}", or "changed and approved" when the approver edited it first.
- A version the assistant wrote at a person's request says "{writer}, via the
  assistant". The person is named as the writer: the assistant wrote on their
  behalf, and their "Allow" was the approval.
- Someone who has left the team appears as "someone who left the team".

Over MCP the history is `talemo_get_knowledge_history`.

## Two people editing

An edit starts from a version. If someone saves the entry first, the second
save is refused with "Someone saved this while you were editing". The text the
person typed is still on the screen: they look at what the entry says now and
save again.

## Removing and bringing back

**Remove** takes an entry out of use: the online admin stops telling it to
clients. The entry is not deleted. It appears under **Removed**, and **Bring
back** returns it at any time. Removing and bringing back are versions too.
A removed entry cannot be edited until it is brought back.

## The assistant changes entries

A person can ask the assistant to write, change, remove or bring back an entry.
The assistant always asks first, in both of its modes, because clients get
answers from the knowledge. The card shows **Now** and **Will be**. If the entry
was changed by someone else while the question waited, the change is not made
and the assistant says so.
See [Approvals in Waiting for you](../assistant/confirmation-cards.md).

## Programs

A program connected over MCP cannot change, remove or bring back an entry. It
suggests, and a person decides (see [Knowledge suggestions](suggestions.md)).
