Changes for version 2.0 - 2018-07-24
- INCOMPATIBLE CHANGE: the node protocol used by this version is not compatible to versions <2 - you have to upgrade all nodes.
- INCOMPATIBLE CHANGE: many APIs have changed, see the section "PORTING FROM VERSION 1" in the AnyEvent::MP manpage for details.
- AnyEvent::MP::Global is now optional - only seed nodes autoload it and create a fully-meshed network with each other, normal nodes only have to connect to seed nodes, other connections are on-demand.
- remove md6 auth algorithms (and use algorithms based on SHA3 instead).
- implement CBOR framing and make it the preferred format.
- new "norc" and "force" options for MP::configure to ignore or override the rc file.
- a shitload of minor and major fixes all reported and debugged by Felix Ostmann.
- move seed code to Kernel.
- non-json receive framing was probably broken.
- fixed small typo in MP::Transport.
- fix (unused) provider-kv (version sometimes missing).
- reduce the default export list of MP::Kernel.
- reduced various random delays to zero, as they are hopefully no longer needed with the new global protocol.
- implement a secure mode that can suppress (some) code execution requests.
- do not use GMP for generating alphanumeric strings even when available, use a more tricky algorithm instead.
- anonymous node names and remote port names have been shortened considerably.
- $AnyEvent::MP::Kernel::SRCNODE contains the node ID of the origin node during message receives.
- aemp shell now supports "package" selection and offers an $ECHO port you can send messages to.
- rely on perl rand() instead of using /dev/urandom when available, as hopefully it is random enough.
- aemp shell no longer leaks one port per command.
- nodenames can contain %-escapes such as %n or %u.
- aemp now uses aemp/%n/%u as nodename.
- configure supports "eval", a small perl snippet to initialsie a node, most useful in "aemp run eval ...".
- known_nodes is gone, it has little value, use all_nodes as replacement.
- lots of small change and improvements.
- node_is_known has been removed.
- TRACE now shows the portid on SND.
- aggressively reduce number of external modules, to reduce memory usage for nodes.
- rework most of the documentation.
- clean up MP::Kernel exports.
- include AnyEvent::MP in AnyEvent::MP::Kernel's @CARP_NOT to hopefully improve error messages.
