# Version 1.0.26

### Why a new version ?

Version 1.0.26 corrects a behavior of the SDK that kept a session open even when the client gave up on a transaction. Consequently, when starting a new transaction, the SDK identified that there was already a session (transaction) in progress, causing an error for those consuming this SDK. A new method has been made available which, when called, eliminates the current session. This way, when starting a new transaction, there will be no session previously in use.

### What are the main changes ?

1 - A method has been made available in the sdk, depending on how the app's screens are built, which should be called when pressing the back button to exit the transaction screen.

A demonstration of how to use this method can be found at the following link in section 5 (Initiate a payment>“Manual stop of the payment process”):

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ftcoders.first-tech.com/first-tech-ttp-sdk/release-notes/version-1.0.26.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
