systemd System and Service Manager
+CHANGES WITH 200:
+
+ * The boot-time readahead implementation for rotating media
+ will now read the read-ahead data in multiple passes which
+ consist of all read requests made in equidistant time
+ intervals. This means instead of strictly reading read-ahead
+ data in its physical order on disk we now try to find a
+ middle ground between physical and access time order.
+
+ * /etc/os-release files gained a new BUILD_ID= field for usage
+ on operating systems that provide continuous builds of OS
+ images.
+
+ Contributions from: Auke Kok, Eelco Dolstra, Kay Sievers,
+ Lennart Poettering, Lukas Nykryn, Martin Pitt, Václav PavlÃn
+ William Douglas, Zbigniew Jędrzejewski-Szmek
+
CHANGES WITH 199:
* systemd-python gained an API exposing libsystemd-daemon.
