- Update to 11.5.0:
* When copying the same page more than once, ensure that annotations
are copied and not shared among multiple pages.
* Add new method Buffer::copy and deprecate Buffer copy constructor
and assignment operator. Buffer copies are expensive and should be
done explicitly.
* The source code was reformatted to 100 columns instead of 80.
Numerous cosmetic changes and changes suggested by clang-tidy were made.
