The inner workings of the breve plugin API have changed as of breve version 2.6. Plugins compiled for earlier versions of breve will not work with breve 2.6 or later.

In most cases, plugins simply need to be recompiled, but should generally not require any changes to code. Additionally, plugins must now be compiled using a C++ compiler (though code written in C will continue to function). See the updated documentation on Plugins Chapter 13 for more information.
