- * Add ability to delete, replace, and swap objects using indirect
-   object references.  This, along with the existing ability to
-   install new indirect objects, significantly increases range of
-   possible modifications.
-
- * QPDFWriter: be able to save to a memory buffer
-
- * Provide an API for returning the keys of a dictionary as a
-   std::map.  Do the corresponding thing for an array.  Provide an
-   example program that does dictionary and array copies perhaps as
-   part of the replace, swap, delete example.
+ * Provide an example of using replace and swap.  Maybe.
 
  * Figure out a way to update the C API with something that can
    update dictionary keys at least with strings.  Make sure it is
    possible to implement something akin to pdf-mod-info in C.
 
- * Fix bug: this->encrypt_metadata is not set when
-   copyEncryptionParameters is used.
-
- * If possible implement the other encrypted file types as reported in
-   bug 3173659.  See ../misc/encrypted-3173659/details.txt for a
-   detailed description of the problems and an extraction of all the
-   test files.
-
+ * Add C API for writing to memory if possible

    use them to override /StmF for specific streams.  I'm not sure

+        Bug fix: when preserving existing encryption on encrypted
+        files with cleartext metadata, older qpdf versions would
+        generate password-protected files with no valid password.
+        This operation now works.  This bug only affected files
+        created by copying existing encryption parameters; explicit
+        encryption with specification of cleartext metadata worked
+        before and continues to work.
