+* Test for binary compatibility. The easiest way to do this is to check out the last release, run the test suite, check out the new release, run `make build_libqpdf`, check out the old release, and run `make check NO_REBUILD=1`.
 * When making a release, always remember to run large file tests and image comparison tests (`--enable-test-compare-images` `--with-large-file-test-path=/path`). For Windows, use a Windows style path, not an MSYS path for large files. For a major release, consider running a spelling checker over the source code to catch errors in variable names, strings, and comments. Use `ispell -p ispell-words`.
 * Run tests with sanitize address enabled:

 # Static Runtime
 
-Building the DLL and executables with static runtime does not work with either Visual C++ .NET 2008 (a.k.a. vc9) using `/MT` or with mingw (at least as of 4.4.0) using `-static-libgcc`.  The reason is that, in both cases, there is static data involved with exception handling, and when the runtime is linked in statically, exceptions cannot be thrown across the DLL to EXE boundary.  Since qpdf uses exception handling extensively for error handling, we have no choice but to redistribute the C++ runtime DLLs.  Maybe this will be addressed in a future version of the compilers.  This has not been retested with the toolchain versions used to create qpdf >= 3.0 distributions. This has not been revisited since MSVC 2008, but redistrbuting runtime DLLs is extremely common and should not be a problem.
