Changes in lyskomd 2.0.0 (Release date TBD)
--------------------------------------------------
* The database format has changed again. Old installations must
convert their old database -- see INSTALL for instructions.
* Portability fixes. This release compiles cleanly on systems that
define errno as a macro.
* It is now possible to attach arbitrary data to conferences and
texts. This allows simple extensions to server data structures
without requiring protocol changes. These data object are called
aux-items, and are configured with the aux-items.conf file.
* It is now possible to see when a membership was added and by whom.
Memberships come in several different flavors through the addition
of a membership type. Currently defined types are secret, passive
and invitation.
* The conference type has been extended so that it is possible to
forbid secret members in the conference.
* Regexp matching is now case insensitive by default. Case sensitivity
is configurable.
* A new recipient type, BCC recipient, has been added. BCC recipients
are only shown to potential members of the recipient and to the
sender.
* The server can send asynchronous messages about texts being deleted;
recipients being added and removed; and memberships being added.
This should help clients with caches to keep them updated.
* There is a call to get the collate table being used by the server.
* The error status field is now set to something semi-useful in all
calls.
* There is a new parameter (keep_commented) on conferences for tuning
the garbage collection process. This tuning is not implemented in
the server, but users and clients are encouraged to start using the
tuning parameter anyway since the tuning will be implemented in the
new feature.
* There is a parameter (expire) for configuring automatic removal of
inactive conferences. This removal is currently not implemented, but
users and clients are encouraged to start using it anyway and the
automatic conference deletion procedure will be implemented in the
near future.
* Documentation has been moved to an info file. The man pages are no
longer maintained.
* The protocol documentation is more detailed, converted to info and
written in English.
* Mapping of local text numbers to global text numbers is now much
more efficient, which should lead to significant performace
improvements if clients make use of these facilities.
* Sanity checks in database and protocol code increase stability and
resilience to client errors and sabotage.
* We now use GNU automake.
* The distribution contains a test suite that is used for regression
testing the server in development. The testsuite should run with no
unexpeced failures.
