This document details the modifications to PyTables since version 1.3. Its main purpose is help you ensure that your programs will be runnable when you switch from PyTables 1.3 to PyTables 1.4.

## API additions

- The `Table.getWhereList()` method has got a new `sort` parameter. The default now is to get the list of parameters unsorted. Set `sort` to True to get the old behaviour. We’ve done this to avoid unnecessary ordering of potentially large sets of coordinates.
- Node creation, copying and moving operations have received a new optional createparents argument. When true, the necessary groups in the target path that don’t exist at the time of running the operation are automatically created, so that the target group of the operation always exists.

## Backward-incompatible changes

- None

## Deprecated features

- None

## API refinements

- `Description._v_walk()` has been renamed to `_f_walk()`, since it is a public method, not a value.
- `Table.removeIndex()` now accepts a column name in addition to an `Index` instance (the later is deprecated). This avoids the user having to retrieve the needed `Index` object.

## Bug fixes (affecting API)

- None
