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

Version 10.1.0 - October 11, 2023

Highlights:
- OpenVDB Python bindings are now implemented using pybind11 instead of
Boost.Python.
[Contributed by Matthew Cong]

OpenVDB:
New features:
- Added points::replicate() for the replication of PointDataGrid points
and attributes.

Improvements:
- OpenVDB Python bindings are now implemented using pybind11 instead of Boost.Python.
[Contributed by Matthew Cong]
- Fix int-in-bool-context GCC9+ warnings by switching to use constexpr if.
- Upgraded OpenVDBs internal half representation to IMath 3.1.6. Brings
conversion support using F16C instructions (if enabled using -mf16c) and
the removal of the exponent lookup table in favor of bit shifting.
- LevelSetRebuild includes disabled code that uses this for
resampling level sets - the original grid is used as the true
sign value. However, due to differences between
polygonalization and trilinear interpolation, it cannot be used
directly. The code is provided so we can learn from this
mistake.
- boost::uuid removed from Archive, instead std::random_device is used
- OpenVDBs copy of Half.h is no longer built with an internal lookup table,
but explicitly selects the non-LUT version and disables the creation of
the LUT. This is required to avoid symbol conflicts with different
namespaced OpenVDB builds.
- Removed boost::uuid from Archive, instead std::random_device is used
directly to generate UUID-like objects.
- Moved all cases of file static/global variables which relied on non-trivial
construction into function scopes as static locals. These would previously
initialize themselves on start-up in a non-deterministic, compiler-dictated
order(static-initialization-order-fiasco). This order is now defined by the
program's execution.
- Introduced openvdb::make_index_sequence to solve clang compilations
issues with compiler built-in index_sequence implementations.
- Fixed the constants used in openvdb::math::Coord::hash() and
nanovdb::Coord::hash() to correctly be prime numbers (note that this
changes the result of these methods).
[Contributed by Benedikt Mersch]
- Updated tools::meshToVolume to take two new optional arguments to provide
an interior test oracle and an interior testing method. These allow the
default outside-flood-fill to be replaced if the actual sidedness can be
known.
[Contributed by Tomas Skrivan]
- LevelSetRebuild now includes example code that demonstrates the intended
use of the new meshToVolume interior testing parameters for the
resampling of level sets, where the original grid is used as the true
sign value. However, due to differences between polygonalization and
trilinear interpolation, this behaviour is disabled and exists as a
reference.
- Introduced openvdb::TupleList to wrap std::tuple and provide interface
interop methods with openvdb::TypeList.
- Added OPENVDB_FORCE_INLINE, OPENVDB_LIKELY and OPENVDB_UNLIKELY macros.
- Introduced openvdb::make_index_sequence to solve clang compilations
issues with compiler built-in index_sequence implementations.

API changes:
- openvdb/tools/MeshToVolume's meshToVolume takes two
new optional arguments to provide an interior test oracle and an
interior testing methods. These allow the default
outside-flood-fill to be replaced if the actual sidedness can be
known.

- PagedArray iterators no longer derive from std::iterator
(but remains standard compliant).
- Significant infrastructural change to the ValueAccessor header and
implementation. All ValueAccessor specializations have been consolidated
into a single class which supports all possible ValueAccessor configurations
using index_sequences. Backward compatible declarations have been provided.
The new ValueAccessor implementation is marked as final.
- PagedArray iterators no longer derive from std::iterator
(but remains standard compliant).

Bug Fixes:
- Fixed a build issue where Boost was not being pulled in when
OPENVDB_USE_DELAYED_LOADING was set to OFF.
- Fixed the constants used in openvdb::math::Coord::hash() and nanovdb::Coord::hash()
to correctly be prime numbers (note that this changes the result of these methods).
[Contributed by Benedikt Mersch]
- Improved support for compiling with C++20.

- OpenVDB's CMake no longer modifies the BUILD_SHARED_LIBS variable.
[Reported by Maksim Shabunin]
- Internal counters in tree::RangeIterator were limited to 32bit precision.
They are now extended to size_t.
