Releases: bluescarni/heyoka
heyoka 0.10.0
This is an incremental release that introduces a change in the API of the callbacks that can (optionally) be passed to the propagate_*() functions. Also, this release features a new pairwise product primitive and various improvements to the automatic simplification capabilities of the expression system.
As usual, the detailed changelog is available here:
heyoka 0.9.0
This release includes two new functions in the expression system: the inverse of Kepler's elliptic equation and time polynomials.
Additionally, this release features also performance improvements and various internal cleanups.
The full changelog, as usual, is available here:
heyoka 0.8.0
This new release of heyoka features a couple of breaking changes in the event detection API. The changes are explained in detail here:
https://bluescarni.github.io/heyoka/breaking_changes.html#bchanges-0-8-0
The release contains also a couple of new features for the propagate_*() functions and a bugfix in the event detection system. As usual, the full changelog is available here:
heyoka 0.7.0
This new release of heyoka comes with several feature additions, a couple of fixes and support for the recently-released LLVM 12.
One important improvement is that the time coordinate in the adaptive integrators is now represented internally in double-length format, which greatly increases time accuracy.
As usual, the full changelog is available here:
heyoka 0.6.1
This is a bugfix release that corrects a couple of issues in the event detection system.
The full changelog, as usual, is available here:
heyoka 0.6.0
This new version of heyoka comes with a big new feature, event detection. A tutorial chapter describing the new feature is available here:
https://bluescarni.github.io/heyoka/tut_events.html
Another important new feature is that propagate_grid() can now be used with the batch integrator.
The full changelog is available here:
heyoka 0.5.0
This is a minor release that features additions and improvements to the expression system.
The full changelog, as usual, is available here:
heyoka 0.4.0
This new release of heyoka comes with several new features:
- support for outputting the Taylor coefficients that were used to perform a single time step,
- support for dense (continuous) output,
- efficient propagation over a time grid via dense output,
- new automatic simplifications in the expression system,
- a new function
powi()for exponentiation with natural exponents.
There is also an important bugfix regarding a division by zero in certain corner cases when using pow() with small natural exponents.
As usual, the full changelog is available here:
heyoka 0.3.0
This new version of heyoka adds support for many new elementary functions, including:
- inverse trigonometric functions,
- (inverse) hyperbolic functions,
- the standard logisitc function,
- the error function.
Additionally, non-autonomous systems are now directly supported via a special time expression.
This release contains also various optimisations, build system improvements and documentation additions.
The full changelog, as usual, is available here:
heyoka 0.2.0
This version adds two important new features:
- support for runtime parameters (i.e., numerical constants whose values is not known when constructing an expression),
- an extension of the API that allows to implement in heyoka a much wider variety of mathematical functions than previously possible. As a showcase for the new API, the tangent function has been implemented. Support for more mathematical functions is planned in the upcoming versions.
