Gadgetviewer v1.2.0

This version is updated to use GTK3 instead of the long-deprecated GTK2. This should make it easier to install on current operating systems.

There should be no differences in behaviour apart from slightly different looking UI widgets, but there have been quite a few internal changes so please report any problems by posting a github issue.

Gadgetviewer v1.1.4

Changes in this release:

• Initial support for reading Gadget-4 subfind output when using halo ordered snapshots
• Ability to read snapshots with particle IDs which are not 4 or 8 bytes each (e.g. Gadget-4's 6 byte IDs)
• Fixes for building in double precision mode (contributed by github user zebo9x)

Gadgetviewer v1.1.3

Changes in this release:

• Several bug fixes in the build system
• Fixed display of integer properties around the selected point
• Fixed a bug that affected reading extra particle properties from additional files

Gadgetviewer v1.1.2

Changes in this release:

• Added SWIFT read routine which can extract sub-regions using the cell structure in SWIFT snapshots
• Removed --use-index command line flag. Spatial indexing is now always used if available.
• EAGLE snapshots are now always read with the EAGLE reader, whether or not a sub-region is requested
• Now compiles with with gfortran 10.2 and HDF5 1.12

Gadgetviewer v1.1.1

• Fixed a bug spotted by Gian Luigi Granato which causes a crash when selecting particles
• Be less picky about fonts used to display startup messages. This prevents messages failing to display when running in an x2go session.
• Fixed a resource leak in VELOCIraptor halo reader

Gadgetviewer v1.1.0

Changes in this release:

• Can now read VELOCIraptor halo finder output
• Fixed a problem that prevented reading Swift snapshots with black holes
• Added a command line option for reading extra quantities from HDF5 snapshots
• Configure script should pick better flags by default

Gadgetviewer v1.0.10

Changes in this release:

• Fixed a font problem on recent versions of Ubuntu
• Prevent crashing on certain Arepo snapshots.

Gadgetviewer v1.0.9

Changes in this release:

• Removed some non-standard code that prevented compilation with recent versions of gfortran
• Modified HDF5 reader to handle AREPO snapshots with tracer particles (we still can't read or visualize the tracers)
• Python script for Fortran module dependencies now works with python 3.

Gadgetviewer v1.0.8

This version fixes a bug that caused particle IDs to be non-unique if they were too large to fit in a signed 64 bit integer.
