v4.7.1

• Bugfix when compiling Scheme C++ projects (e.g. Meep) with libctl geometry utils (#94).

• Reduce intermittent test failures (#93).

• Fix make distclean to remove files generated by make check (#96).

v4.7.0

• New mesh geometry object (#74).

• Bug fixes for thread safety (#75, #81).

• Enable thread-safety tests via configure flag --enable-openmp (#79); the library itself is still single-threaded (but many functions of libctlgeom are thread-safe).

• CI workflow via Github Actions (#85).

v4.6.0

• Python-callable extension (#71), currently with limited documentation.

• Fix memory leak for prism objects (#73).

v4.5.1

• Ignore duplicate consecutive prism vertices (#60).

• Memory bug fixes (#58, #59).

v4.5.0

• New make_slanted_prism functions to make a prism with
  a given sidewall angle (#53).

• Defined LIBCTL_MAJOR_VERSION etc. in ctlgeom.h header file when
  using stand-alone libctlgeom.

• Bugfix in point-in-prism test (#49).

v4.4.0

• geom_object_volume function to get the volume of a 3d object
  (accelerates box_overlap_with_object for objects completely within a box) (#45).

• Bugfix to geometry tree search for empty dimensions.

v4.3.0

ctl_printf_callback so that callers can capture stdout (#39).

v4.2.0

Better handling of center parameter of prisms, allowing this
to be optionally specified (#35).

Libctl 4.1.4

Work around gcc bug (closes #32). Allow subclass properties to override defaults (or lack thereof) in parent class.

Libctl 4.1.3

Improved prism handling of points on prism faces (#23) and various cosmetic improvements (#22, #24, #25).
