I'd like to second this notion in the same spirit with which it was put forward. Silence and secrecy may be justified when a company is about to launch something that no one else has. But what would be wrong with:
We are rewriting the report formats
We hope to improve the search and indexing functions
We are establishing <[note]> for use in our sentence templates
None of those assertions can harm the company. Indeed, one could argue that user loyalty might be enhanced.
Finally, if RootsMagic isn't doing those things, it ought to.
