A word about update packages

The purpose of the update package is to enable you to update your binder quickly and easily - rather than having to download an entire specification, you can download just the parts that have changed. Update packages contain new chapters, changes made to other chapters (if applicable), as well as an updated title page, table of contents, list of figures, list of tables, preface, overview, and index. Additionally, the package includes instructions for modifying your current binder. The update package format is similar to the hardcopy updates that you received in the past.

IMPORTANT: Update packages are sequential. To avoid consistency issues, please make sure you have updated your binder with all the update packages that are listed for a book (e.g., CORBA,CORBAservices, etc.)
