# Changes

## 0.8: 2014-07-17

- Support for Python 3 added.

## 0.7.0: 2011-12-29

- 0.7.0 relies on libspatialindex 1.7.1+.
- int64_t’s should be used for IDs instead of uint64_t (requires libspatialindex 1.7.1 C API changes)
- Fix __version__
- More documentation at http://toblerity.github.com/rtree/
- Class documentation at http://toblerity.github.com/rtree/class.html
- Tweaks for PyPy compatibility. Still not compatible yet, however.
- Custom storage support by Mattias (requires libspatialindex 1.7.1)

## 0.6.0: 2010-04-13

- 0.6.0 relies on libspatialindex 1.5.0+.
- `intersection()` and `nearest()` methods return iterators over results instead of lists.
- Number of results for `nearest()` defaults to 1.
- libsidx C library of 0.5.0 removed and included in libspatialindex
- objects=”raw” in `intersection()` to return the object sent in (for speed).
- `count()` method to return the intersection count without the overhead of returning a list (thanks Leonard Norrgård).
- Improved bulk loading performance
- Supposedly no memory leaks :)
- Many other performance tweaks (see docs).
- Bulk loader supports interleaved coordinates
- Leaf queries. You can return the box and ids of the leaf nodes of the index. Useful for visualization, etc.
- Many more docstrings, sphinx docs, etc

## 0.5.0: 2009-08-XX

0.5.0 was a complete refactoring to use libsidx - a C API for libspatialindex. The code is now ctypes over libsidx, and a number of new features are now available as a result of this refactoring.

- ability to store pickles within the index (clustered index)
- ability to use custom extension names for disk-based indexes
- ability to modify many index parameters at instantiation time
- storage of point data reduced by a factor of 4
- bulk loading of indexes at instantiation time
- ability to quickly return the bounds of the entire index
- ability to return the bounds of index entries
- much better windows support
- libspatialindex 1.4.0 required.

## 0.4.3: 2009-06-05

- Fix reference counting leak #181

## 0.4.2: 2009-05-25

- Windows support

- Switch dependency to the single consolidated spatialindex library (1.3).

## 0.3: 26 November 2007

- Change to Python long integer identifiers (#126).
- Allow deletion of objects from indexes.
- Reraise index query errors as Python exceptions.
