CHANGES FOR BETA 5
==================

Utils
=====

1) Recompilation times faster. Now adding or removing thorns does not involve
a complete rebuild

2) Initial implementation of timing information, use parameter Cactus::timing_


Util Thorns
===========

1) CactusBase/Boundary: Robin boundary conditions added

2) CactusPUGHIO/IsoSurfacer: Now works correctly for data from analysis routines


Relativity Thorns
=================

1) CactusEinstein/TimeGeodesic: New thorn: Tracks timelike geodesics
with given initial positions and velocities.

2) CactusEinstein/AHFinder: New thorn: locates apparent horizons on a
slice

==============================================================================


KNOWN BUGS IN BETA 5
====================
(See Cactus bug tracking system for a complete list)

1) CactusNet/http, external/TCPXX, external/RemoteIO still not compiling
on all platforms

2) EllPETSc only compiles with MPI, but doesn't tell you this

3) AxiBrillBH has problems on some platforms


==============================================================================


WHAT TO EXPECT IN BETA 6
========================

1) Fixes for all known bugs in Beta 5

2) Finished implementation of 1D, 2D, 3D arrays

3) Maximal slicing

4) Generic implementation of parameter choice for elliptic slicings
