9 ## DragonFly 2.2 Release Notes
12 * First step towards AMD64 support (done by Jordan Gordeev during the Google Summer of Code 2008).
13 * The system control *intr_mpsafe* is enabled by default.
14 * Move <tt>/kernel</tt> to <tt>/boot/kernel</tt> and <tt>/modules</tt> to <tt>/boot/modules</tt>.
15 * Add RFC3542 support (done by Dashu Huang during the Google Summer of Code 2008).
16 * Add HW checksum support to the loopback interface, which doubles performance.
17 * acpi_cpu(4) update. It's now possible to use higher (lower power usage) C states than C1 in modern (multicore) CPUs.
18 * Add HAMMER read support to the boot loader.
19 * First steps to use network threads without the Big Giant Lock (this feature is considered experimental).
20 * Fixed CVE-2008-2476 IPv6 security issue with modified patches from NetBSD.
21 * <tt>bridge_input</tt> works now in parallel.
22 * Fix bugs in dealing with low-memory situations when the system has run out of swap or has no swap.
23 * Major rewrite of usched_bsd4 and related support logic, plus additional improvements to the LWKT scheduler.
24 * Major revamping of the pageout and low-memory handling code.
25 * suser_* replaced with priv_* implementation from FreeBSD.
29 * Use per-mount kmalloc pools for bulk data structures, particularly inodes and records.

37 * Add acpi_video(4) - a driver for ACPI video extensions (from FreeBSD).
38 * It is possible to power down PCI devices during detach. This should save some power when using mobile devices (from FreeBSD).
