This should make the ps + tree a lot more organized. + + * A new PartOf= unit dependency type has been introduced that + may be used to group services in a natural way. + + * "systemctl enable" may now be used to enable instances of + services. + + * journalctl now prints error log levels in red, and + warning/notice log levels in bright white. It also supports + filtering by log level now. + + * cgtop gained a new -n switch (similar to top), to configure + the maximum number of iterations to run for. It also gained + -b, to run in batch mode (accepting no input). + + * The suffix ".service" may now be ommited on most systemctl + command lines involving service unit names. + + * There's a new bus call in logind to lock all sessions, as + well as a loginctl verb for it "lock-sessions". + + * libsystemd-logind.so gained a new call sd_journal_perror() + that works similar to libc perror() but logs to the journal + and encodes structured information about the error number. + + * /etc/crypttab entries now understand the new keyfile-size= + option. + + * shutdown(8) now can send a (configurable) wall message when + a shutdown is cancelled. + + * The mount propagation mode for the root file system will now + default to "shared", which is useful to make containers work + nicely out-of-the-box so that they receive new mounts from + the host. This can be undone locally by running "mount + --make-rprivate /" if needed. + + * The prefdm.service file has been removed. Distributions + should maintain this unit downstream if they intend to keep + it around. However, we recommend writing normal unit files + for display managers instead. + + * Since systemd is a crucial part of the OS we will now + default to a number of compiler switches that improve + security (hardening) such as read-only relocations, stack + protection, and suchlike. + + * The TimeoutSec= setting for services is now split into + TimeoutStartSec= and TimeoutStopSec= to allow configuration + of individual time outs for the start and the stop phase of + the service. + + Contributions from: Artur Zaprzala, Arvydas Sidorenko, Auke + Kok, Bryan Kadzban, Dave Reisner, David Strauss, Harald Hoyer, + Jim Meyering, Kay Sievers, Lennart Poettering, Mantas + Mikulėnas, Martin Pitt, Michal Schmidt, Michal Sekletar, Peter + Alfredsen, Shawn Landden, Simon Peeters, Terence Honles, Tom + Gundersen, Zbigniew Jędrzejewski-Szmek + +CHANGES WITH 187: + + * The journal and id128 C APIs are now fully documented as man + pages. + + * Extra safety checks have been added when transitioning from + the initial RAM disk to the main system to avoid accidental + data loss. + + * /etc/crypttab entries now understand the new keyfile-offset= + option. + + * systemctl -t can now be used to filter by unit load state. + + * The journal C API gained the new sd_journal_wait() call to + make writing synchronous journal clients easier. + + * journalctl gained the new -D switch to show journals from a + specific directory. + + * journalctl now displays a special marker between log + messages of two different boots. + + * The journal is now explicitly flushed to /var via a service + systemd-journal-flush.service, rather than implicitly simply + by seeing /var/log/journal to be writable. + + * journalctl (and the journal C APIs) can now match for much + more complex expressions, with alternatives and + disjunctions. + + * When transitioning from the initial RAM disk to the main + system we will now kill all processes in a killing spree to + ensure no processes stay around by accident. + + * Three new specifiers may be used in unit files: %u, %h, %s + resolve to the user name, user home directory resp. user + shell. This is useful for running systemd user instances. + + * We now automatically rotate journal files if their data + object hash table gets a fill level > 75%. We also size the + hash table based on the configured maximum file size. This + together should lower hash collisions drastically and thus + speed things up a bit. + + * journalctl gained the new "--header" switch to introspect + header data of journal files. + + * A new setting SystemCallFilters= has been added to services + which may be used to apply blacklists or whitelists to + system calls. This is based on SECCOMP Mode 2 of Linux 3.5. + + * nspawn gained a new --link-journal= switch (and quicker: -j) + to link the container journal with the host. This makes it + very easy to centralize log viewing on the host for all + guests while still keeping the journal files separated. + + * Many bugfixes and optimizations + + Contributions from: Auke Kok, Eelco Dolstra, Harald Hoyer, Kay + Sievers, Lennart Poettering, Malte Starostik, Paul Menzel, Rex + Tsai, Shawn Landden, Tom Gundersen, Ville Skyttä, Zbigniew + Jędrzejewski-Szmek + CHANGES WITH 186: * Several tools now understand kernel command line arguments, @@ -14,7 +142,7 @@ CHANGES WITH 186: * We now provide an early debug shell on tty9 if this enabled.
