# Upgrading from older pysmb versions

This page documents the improvements and changes to the API that could be incompatible with previous releases.

## pysmb 1.2.0

- Add new delete_matching_folders parameter to deleteFiles() method in SMBProtocolFactory and SMBConnection class to support deletion of sub-folders. If you are passing timeout parameter to the deleteFiles() method in your application, please switch to using named parameter for timeout.

## pysmb 1.1.28

- SharedFile instances returned from the listPath() method now has a new property file_id attribute which represents the file reference number given by the remote SMB server.

## pysmb 1.1.26

- SMBConnection class can now be used as a context manager

## pysmb 1.1.25

- SharedFile class has a new property isNormal which will be True if the file is a ‘normal’ file. pysmb defines a ‘normal’ file as a file entry that is not read-only, not hidden, not system, not archive and not a directory; it ignores other attributes like compression, indexed, sparse, temporary and encryption.

- listPath() method in SMBProtocolFactory and SMBConnection class will now include ‘normal’ files by default if you do not specify the search parameter.

## pysmb 1.1.20

- A new method getSecurity() was added to SMBConnection and SMBProtocolFactory class.

## pysmb 1.1.15

- Add new truncate parameter to storeFileFromOffset() in SMBProtocolFactory and SMBConnection class to support truncation of the file before writing. If you are passing timeout parameter to the storeFileFromOffset() method in your application, please switch to using named parameter for timeout.

## pysmb 1.1.11

- A new method storeFileFromOffset() was added to SMBConnection and SMBProtocolFactory class.

## pysmb 1.1.10

- A new method getAttributes() was added to SMBConnection and SMBProtocolFactory class

- SharedFile class has a new property isReadOnly to indicate the file is read-only on the remote filesystem.

## pysmb 1.1.2

- queryIPForName() method in nmb.NetBIOS and nmb.NBNSProtocol class will now return only the server machine name and ignore workgroup names.

## pysmb 1.0.3

- Two new methods were added to NBNSProtocol class: queryIPForName() and NetBIOS.queryIPForName() to support querying for a machine’s NetBIOS name at the given IP address.

- A new method retrieveFileFromOffset() was added to SMBProtocolFactory and SMBConnection to support finer control of file retrieval operation.

## pysmb 1.0.0

pysmb was completely rewritten in version 1.0.0. If you are upgrading from pysmb 0.x, you most likely have to rewrite your application for the new 1.x API.
