* This release consists entirely of changes made by M. Holger.
Mostly this is changes to the private API, performance
enhancements, code cleanup, and reformatting to 100 columns
instead of 80. For qpdf development, we are starting to use
JetBrains CLion, so a lot of the changes are moving us toward a
cleaner development experience in that environment.

* Bug fix: when a the same page is copied multiple times, copy
the annotations rather than having multiple pages share an
annotation object. Thanks to M. Holger for the fix. Fixes #600.

* Add "FUTURE" build option for enabling experimental APIs. Do not
package qpdf built with the FUTURE option as there are no binary
compatibility or even source compatibility guarantees. The option
is intended for developers who want to ensure that future
potentially breaking changes are compatible with their code or
provide feedback on upcoming changes. At present, the only feature
enabled by FUTURE is a move constructor for QPDFObjectHandle.
While this shouldn't break any code, it would change details about
how many copies of a specific QPDFObjectHandle were in existence,
so it could potentially break code that was relying on internal
shared pointer reference counts. Thanks to M. Holger for the idea
and contribution.

* Add new method Buffer::copy and deprecate Buffer copy
constructor and assignment operator. Buffer copy operations are
expensive as they always involve copying the buffer content. Use
"buffer2 = buffer1.copy();" or "Buffer buffer2{buffer1.copy()};"
to make it explicit that copying is intended. This change was
contributed by M. Holger.

it explicit that copying is intended.

11.5.0: July 9, 2023
- Bug Fixes
- When copying the same page more than once, ensure that
annotations are copied and not shared among multiple pages.
- Build Changes
- Add new ``FUTURE`` build option. This option enables you to test
code against proposed changes to qpdf's API. See
:ref:`build-options` for details. Packagers: do not package qpdf
with the ``FUTURE`` option enabled as there are no API/ABI
compatibility guarantees when the option is turned on.
- Library Enhancements
- Add new method ``Buffer::copy`` and deprecate ``Buffer`` copy
constructor and assignment operator. ``Buffer`` copies are
expensive and should be done explicitly.
- Miscellaneous Changes
- The source code was reformatted to 100 columns instead of 80.
Numerous cosmetic changes and changes suggested by clang-tidy
were made. M. Holger did all the hard work.
11.4.0: May 21, 2023
