Releases: oorb/oorb
OpenOrb 1.3.0
It's been a while, huh. :)
In this release we have some linear algebra related bugfixes that affect at least mass estimation and the covariance sampling tasks alongside some smaller miscellaneous fixes.
HIghlighted features include support for newer JPL ephemerides (DE441), initial support for Gaia DR3 astrometry (to be added is the relativistic light bending correction), and also pyoorb now being available through PyPI .
As a cautionary note, the structure of OpenOrb's orbit files has changed slightly since the previous version. Strange behavior may occur if using such orbits in OpenOrb for further processing, and it is recommended to recompute these.

OpenOrb v1.3.0a
Test release to comfirn PyPI publishing is functioning correctly. Official release soon to follow..
OpenOrb 1.2.0
OpenOrb 1.2.0 is primarily characterized by further development on the asteroid mass estimation algorithms included, particularly in combination with Gaia data. Several tweaks were done to the MCMC and marching algorithms including cleanups, bugfixes and algorithmic tweaks. In addition, several formerly command line parameter only mass estimation options were added to oorb.conf.
On the build system side, support for the flang compiler (version 12+ is required) was added alongside a new conda option that currently needs to be used when building oorb with conda packages.
A relativistic light bending correction was included for use with Gaia DR2 data (and is always used by default).
A new oorb_observer routine was included in pyoorb for fetching the observer's location (#129) and a minor bug with ranging (#87) was fixed.
Finally, as was already the case for other data files, oorb now looks for the BC430 ephemerides in PREFIX/share/oorb if the OORB_DATA environment variable is not defined. Similarly, PREFIX/share/oorb/gnuplot is now the default directory for the gnuplot scripts. Here PREFIX is a directory given during compilation time.
For the curious, the shortlog is appended below.
Enjoy!

OpenOrb 1.1.0
Here is the first official OpenOrb release on Github and the first version bump in more than 8 years.
In the future, we intend to write release notes describing what's new in each release but given the very long time since the previous version bump we will not do for this one.
Enjoy!
