responded suggesting that talk to -release re paragraphs 2 and 3, and to
-security re paragraph 4. Comments welcome, and CCs appreciated. --Dirk ]

| CHANGES IN R VERSION 2.10.0
|
|
| SIGNIFICANT USER-VISIBLE CHANGES
|
| o Package help is now converted from Rd by the R-based converters
| that were first introduced in 2.9.0. This means
|
| - Packages that were installed by R-devel after 2009-08-09
| should not be used with earlier versions of R, and most
| aspects of package help (including the runnable examples)
| will be missing if they are so used.
|
| - Text, HTML and latex help and examples for packages
| installed under the new system are converted on-demand from
| stored parsed Rd files. (Conversions stored in packages
| installed under R < 2.10.0 are used if no parsed Rd files
| are found. It is recommended that such packages be
| re-installed.)
|
|
| o HTML help is now generated dynamically using an HTTP server
| running in the R process and listening on the loopback
| interface.
|
| - Those worried about security implications of such a server
| can disable it by setting the environment variable
| R_DISABLE_HTTPD to a non-empty value. This disables
| help.start() and HTML help (so text help is shown instead).
|
| - The Java/Javascript search engine has been replaced by an
| HTML interface to help.search(). help.start() no longer has
| an argument 'searchEngine' as it is no longer needed.
|
| - The HTML help can now locate cross-references of the form
| \link[pkg]{foo} and \link[pkg:foo]{bar} where 'foo' is an
| alias in the package, rather than the documented (basename
| of a) filename (since the documentation has been much
| ignored).
