Release history

This section summarizes the release history of Pastel.

Conventions

Versioning

The versioning of Pastel is given in the form x.y.z, where x, y, and z are integers. The x increments only for major changes, the y increments for feature changes, and the z increments for bug fixes or documentation updates. Whenever y is incremented, z is zeroed, and whenever x is incremented, both y and z are zeroed. The x, y, and z need not consist of a single digit, and, for example, 1.12.0 is a much later version than 1.1.3.

Previous versions

It is possible to visit the webpages of a previous version by visiting the address

http://kaba.hilvi.org/pastel-x.y.z

where x.y.z is a version number. That webpage then works as it did on the time of release, and can be used to obtain the older software.

Pastel 1.2.0

Release data 17.3.2011

PastelMatlab

A new library to aid in interfacing Pastel with Matlab.

PastelGeometryMatlab

A new library to offer a Matlab interface to a subset of PastelGeometry.

PastelGeometry

Added an ''O(n log(n))'' box maximum clique algorithm.
Added a set-difference algorithm for boxes.
Added a way to define the openness of shapes.
Turned nearest neighbor searching on kd-trees into a generic implementation on which variants can be implemented as customizations.
Removed the support for bucket nodes from PointKdTree because of no gain.
Nearest neighbor searching on PointKdTree: removed hint-distances and bottom-up searching because of negligible gain.
Implemented range searching and range counting algorithms on PointKdTree.
Improved the brute-force nearest neighbors searching implementation.
Changed to use open search regions in nearest-neighbors and range searching.
Lifted PointPolicy_PointKdTree concept to a global PointPolicy concept.

PastelDsp

Added the computation of the discrete cosine transform, the discrete fourier transform, the discrete Haar transform, and the discrete Hadamard transform.
Added the algorithm object concept.

PastelSys

Added an augmented red-black tree.
Generalized vector expressions to mix between dynamic and compile-time dimensions.
Added a way to specify different actions on invariant failures.
Added finalization for loggers, to give them an opportunity to flush buffered output before aborting a program.
Added a progress reporter class.
Added goodness-of-fit tests for random variables.
Added a way to specify storage ordering in Array.

Build system

Changed to use the Premake build system, which generates the environment-specific build files.
The code now compiles on Windows, Linux, and Mac, on both Visual Studio and gcc, and in 32-bit and 64-bit modes.

Others

A lot of refactoring, bug fixes, and updates to documentation.
Documentation built on Remark 1.3.

Pastel 1.1.0

Release date 13.3.2010.

PastelGeometry

Added best-first algorithm to nearest neighbors searching and made it the default.
Added hint-distances to nearest neighbors searching to make it possible to make use of temporal coherence.
Added median-of-longest-side splitting rule for PointKdTree.

PastelSys

Fixed a bug with nextSmaller and nextGreater function.
Added isNan.

PastelGfxUi

A new library to offer a simple graphical gui.

Pastel 1.0.1

Release date 13.1.2010.
