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)

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

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

• 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

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

Changes in this release:

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

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.

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.
