+ The release_handler functionality on windows services was
+ broken. This has been corrected.</p>
+ <p>
+ Own Id: OTP-9306</p>
+ </item>
+ <item>
+ <p>
+ If a new version of an application did not include any
+ erlang module changes, the code path of the application
+ was not updated by the release_handler unless a
+ 'load_object_code' instruction was added for the
+ application. This would be a problem if e.g. only some
+ files in the priv dir were changed since calls to
+ code:lib_dir or code:priv_dir would then point to the old
+ location of the application. This has been corrected -
+ now code:replace_path/2 will be called for all
+ applications that are changed (i.e. when the
+ application's vsn is changed in the .rel file).</p>
+ <p>
+ Own Id: OTP-9402</p>
+ </item>
+ <item>
+ <p>
+ The appup instruction 'delete_module' would cause a crash
+ during upgrade if the module to be deleted was not
+ loaded. This has been corrected.</p>
+ <p>
+ Own Id: OTP-9417</p>
+ </item>
+ <item>
+ <p>
+ If a path was given as ONLY 'ebin' and not for example
+ './ebin', then systools:make_tar would fail with a
+ <c>function_clause</c> exception in filename:join/1. This
+ has been corrected. (Thanks to Nikola Skoric for
+ reporting).</p>
+ <p>
+ Own Id: OTP-9507</p>

+ <p>
+ Implement or fix -Werror option</p>
+ <p>
+ If -Werror is enabled and there are warnings no output
+ file is written. Also make sure that error/warning
+ reporting is consistent. (Thanks to Tuncer Ayaz)</p>

+ Improved error information for timeouts during
+ release_handler:install_release.</p>
+ <p>
+ This patch addresses two cases where a timeout will occur
+ during upgrade. 1) if a supervisor is suspended (call to
+ get children from supervisor will hang) 2) if the child
+ spec for a supervisor incorrectly states that it is a
+ worker with a dynamic set of modules (call to get modules
+ from gen_event will hang)</p>
+ <p>
+ An error report will now be printed, and the return value
+ of release_handler:install_release will indicate what
+ happened. (Thanks to joe williams)</p>

+ <p>
+ <c>release_handler:install_release</c> could be very slow
+ when there are many processes in the system. Some
+ optimization work has been done both in erts and in the
+ release handler in order to improve this. </p>
+ <p>
+ A new option, <c>purge</c>, is added to
+ <c>release_handler:check_install_release</c> which can be
+ called first in order to speed up the execution of
+ <c>release_handler:install_release</c>.</p>
