.The

If you wish to rebuild these, or are building from a git clone in which they are not pregenerated, you will need to install
sphinx-build
, and the perl modulePod::POM::View::Restructured
. The top level Makefile now hasman
anddoc
targets. for building these.Added support for OpenSSL 1.1.0-pre5.
Significant bugfixes¶

Includes the addition of a new daemon (calalarmd) which periodically processes a global database containing the “next” alarm for each item, and sends the relevant mboxevents. (See configure.ac
--with-calalarmd
)Replication reliability fixes.
