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

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

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

320   - * When an annotation dictionary's appearance dictionary (`/AP`)
321   - has a key that is a stream, disregard `/AS` (which is supposed to
322   - point to a subkey). This enables qpdf to not ignore annotations
323   - that have incorrect values for `/AS` when the appearance stream is
324   - directly in the `/AP` dictionary instead of in a subkey. Fixes
325   - #949.

330   - before it is written. This adds methods QPDFJob::createQPDF and
331   - QPDFJob::writeQPDF and corresponding C API functions
332   - qpdfjob_create_qpdf and qpdfjob_write_qpdf. Thanks to M. Holger

547 547  
548   - * include/qpdf/JSON.hh: Schema validation: allow a single item to
549   - appear anywhere that the schema has an array of a single item.
550   - This makes it possible to change an element of the schema from an
551   - item to an array to allow the data to accept an array where a
552   - single value was previously required. This change is needed to
553   - allow QPDFJob JSON to start accepting multiple items where a
554   - single item used to be expected without breaking backward
555   - compatibility. Without this change, the earlier fix to
556   - removeAttachment would be a breaking change. Also allow the schema
557   - to contain a multi-element array, which means that the output has
558   - to have an array of the same length in the corresponding location,
559   - and each element is validated against the corresponding schema
560   - element.
561   -
562   - * QPDFObjectHandle: for the methods insertItem, appendItem,
563   - eraseItem, replaceKey, and removeKey, add a corresponding
564   - "AndGetNew" and/or "AndGetOld" methods. The ones that end with
565   - "AndGetNew" return the newly added item. The ones that end with
566   - "AndGetOld" return the old value. The AndGetNew methods make it
567   - possible to create a new object, add it to an array or dictionary,
568   - and get a handle to it all in one line. The AndGetOld methods make
569   - it easier to retrieve an old value when removing or replacing it.

571   - * Thanks to m-holger for doing significant cleanup of private APIs
572   - and internals around QPDFObjGen and for significantly improving

578   - specification of a separator character, with the default

580   - Examples have been updated to use improved APIs. The old
