-        * Fix data loss bug: qpdf could discard a the character after an
-        escaped octal string consisting of less than three digits. For
-        content, this would only happen with QDF or when normalizing
-        content. Outside of content, it could have happened in any binary
-        string, such as /ID, if the encoding software used octal escape
-        strings with less than three digits. This bug was introduced
-        between 10.6.3 and 11.0.0. Fixes #1050.

-        * 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.

-        reserved object fits better in the QPDF API. The old call just
-        delegates to the new one.

-        * When an annotation dictionary's appearance dictionary (`/AP`)
-        has a key that is a stream, disregard `/AS` (which is supposed to
-        point to a subkey). This enables qpdf to not ignore annotations
-        that have incorrect values for `/AS` when the appearance stream is
-        directly in the `/AP` dictionary instead of in a subkey. Fixes
-        #949.

-        * Allow QPDFJob's workflow to be split into a reading phase and a

-        before it is written. This adds methods QPDFJob::createQPDF and

-        qpdfjob_create_qpdf and qpdfjob_write_qpdf. Thanks to M. Holger

-        * When performing overlay or underlay operations, convert the

-        operators in any of the original pages from messing up the
-        graphics state of anything that is overlaid on top of it. Fixes
-        #904.

-        * More optimizations and cleanup from m-holger (#726, #730)
-        including major refactor of QPDF's internal representations of

-        complete solution to this problem will be introduced for qpdf 12.)
-        This work also paves the way for a future alternative to
-        QPDFObjectHandle that is more idiomatic C++ and has greater type

-        * include/qpdf/JSON.hh: Schema validation: allow a single item to

-        This makes it possible to change an element of the schema from an
