16th May 2013: Leave a comment!

PASA, the journal in which the paper describing SPLASH is published, has just switched publishers to Cambridge University Press. The cool thing about this is that there is now the ability to comment on articles that are, or were, published in PASA. Thus, to encourage the use of this rather experimental feature in Astronomy journals, I would like to invite splash users to leave a comment/feedback regarding splash on the splash paper.

26th April 2013: giza repositories have moved!

Due to an upgrade to the sourceforge platform, the address of the giza repository has moved. This means that if you have a svn copy of splash you will need to check out a fresh copy of giza from the new repository:

cd splash
rm -r giza
svn co http://svn.code.sf.net/p/giza/code giza
make clean
make

31st Aug 2012: v2.1.1 released (full release notes here).

This is a "quasi-minor" release, there's no big new features, but a lot of small things have been improved/fixed. As such, I highly recommend it for all users. Summary of new features as follows:

16th May 2012: v2.1.0 released.

First stable release with the giza backend. New features are as in 2.0-beta, plus:

1/5/12: SPLASH on the cover of A&A!

Shazrene Mohamed's beautiful SPLASH-made images from simulations of Betelgeuse's bow shock made the front cover of Astronomy & Astrophysics

29/08/11: v2.0 beta released.

This is a beta release of SPLASH 2.0. New features are as in 1.15.0, plus:

Initially users will notice relatively few changes from the old PGPLOT backend, except that plots look *a lot* nicer. Indeed for backwards compatibility SPLASH can still be compiled with PGPLOT as the backend using "make BACKEND=pgplot". However, this will become progressively more obsolete as features not supported in PGPLOT are added over time (e.g. double rendering).

Please *let me know* of any problems you encounter using the beta version.

29/08/11: v1.15.0 released.

This is the last in the 1.x.x series (with PGPLOT as default). New features are:

Get it from the download page or via `svn update'.

14/06/11: SPLASH hits 100

I was thinking of promising a new major version every 100 citations, but that could be dangerous... thanks for the credits though!

12/06/11: SPLASH @ Astrobites

Nathan Goldbaum has posted a nice beginners tutorial to running SPH simulations, including getting started with SPLASH + GADGET at Astrobites.com.

17/03/11: v1.14.1 released.

This is a minor update. New features are:

26/02/10: v1.13.1 released.

This is mainly a bug-fix release to v1.13.0, highly recommended for all users. Main changes are:

Thanks go to Florian Buerzle and Jean-François Gonzalez for eager bug-reporting...

25/02/10: v1.13.0 released.

It's been far too long between releases, but there are some substantial new features in this one. These are as follows:

25/02/10: SPLASH hits 50

Thanks!

18/01/10: Great things are afoot...

...in splash development. You'll find out more in due course.

18/01/10: Get the latest!

SPLASH now has a public svn repository, so you can check out the latest and greatest code at any time. Just use:

svn co https://svn-vre.its.monash.edu.au/mathsci/splash

to get the latest. The splash repository is pretty stable on the whole, though you may find some changes-in-progress. Once you have obtained splash this way though, it is very simple to upgrade to the latest version: Just enter the splash/ directory and type:

svn update

then simply "make" to recompile the code.

15/07/09: v1.12.2 released.

This is a minor release, main things are as follows:

20/04/09: v1.12.1 released.

This is a minor release, where the main new things are as follows: * or redefined as features.

22/12/08: v1.12.0 released.

* or redefined as features.

13/10/08: v1.11.1 released.

This update is highly recommended for ALL users. It corrects a bug/issue which has bothered me for a long time - namely that the SPLASH pixel map does not always line up with the pixel map on the PGPLOT device, resulting in slight artefacts in the images produced. Now, SPLASH determines the resolution automatically to exactly match the device (this is now the default behaviour, can be overridden with a manual pixel number selection). Also, the edges of the plot are set to exactly lie on pixel boundaries, hopefully removing the "black lines" sometimes found inside the colour bar on pixel plots. The automatic resolution feature is really one of the main things in v1.11.0 but I had disabled it as there were a few issues to be ironed out. Other features in v1.11.1 include the ability to render images without having to store mass as a particle array (ie. can be read as a single value for each particle type). See version history in the userguide or the change log for full details.

03/09/08: New SPLASH website!

With some improvement on my previously fairly ordinary web design skills...

15/08/08: v1.11.0 released.

Main new feature is to be able to plot subsets of the particles according to restricted parameter ranges (e.g. only use particles with 1 < rho < 10). Also plot-hugging colour bars added and the ability to annotate plot with a range of shapes. Bugs fixed in GADGET data read (for particle masses < 1.e-8), also with calculation of v_phi in cylindrical coordinates. UCLA data read added. See version history in the userguide or the change log for full details.

05/06/08: v1.11.0beta released.

This was a pre-release of v1.11.0.

08/05/08: v1.10.2 released.

This is a minor update. New features include the ability to plot azimuthally averaged profiles of surface density and Toomre Q parameter for discs; can override column labelling using a splash.columns file; can change the order in which particle types are plotted. See version history in the userguide or the change log for full details.

11/03/08 v1.10.1 released.

This is a minor release. Main new things are the "splash to" command line utility which converts binary dump files to ascii format and that vector plots now work with rotation. Improvements also to GADGET data read (block-labelled format implemented; reads optional file for dark matter smoothing lengths). See version history in the userguide or the change log for full details.

28/11/07 v1.10.0 released.

Main new features are horizontal colour bars, the -p and -o command line options, the ability to mix particle types in the data read and implemented data reads for TIPSY and DRAGON formats. See version history in the userguide or the change log for details.

12/9/07 v1.9.2 released.

This is a minor update only. See version history/change log for details.
