Minor memory leaks are a known issue, but due to the size of CKEditor and level of its complexness, number of supported browsers and high level of code branching caused by the browsers, the cost of fixing them is high. We focus therefore on significant memory leaks only. For instance, few months ago a problem with CKEDITOR.filter instances was fixed because filter instances are pretty costly for the memory. If you spotted any other memory leak of this size, please let us know.
