1 Introduction
This errata document contains “late-breaking news” about FreeBSD 7.0-RELEASE. Before installing this version, it is important to consult this document to learn about any post-release discoveries or problems that may already have been found and fixed.
Any version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the “current errata” for this release. These other copies of the errata are located at http://www.FreeBSD.org/releases/, plus any sites which keep up-to-date mirrors of this location.
Source and binary snapshots of FreeBSD 7-STABLE also contain up-to-date copies of this document (as of the time of the snapshot).

3 Open Issues
[20080229] tcpdump(1) does not correctly print the TX/RX rates for 802.11 frames. This issue has been fixed on the HEAD and RELENG_7 branches.
[20080229] A bug in Linux emulation may cause segmentation faults for some Linux programs using mmap(2). This issue has been fixed on the HEAD and RELENG_7 branches.
[20080229] Instances of packet corruption and instability have been observed with the re(4) network driver. Some users have reported that using a newer version of this driver (on HEAD) has solved their problems, or at least mitigated them.
[20080229, updated 20080817] A change in the way that FreeBSD sends TCP options has been reported to cause connectivity issues. This problem has been corrected on HEAD and the RELENG_7 and RELENG_7_0 branches.. Further details are contained in errta notice FreeBSD-EN-08:02.tcp.
[20080307] The FreeBSD implementation of SCTP currently depends on having INET6 support compiled into the kernel. This requirement is planned to be removed in future releases.
[20080307] Source upgrades from FreeBSD 6.X to FreeBSD 7.0-RELEASE will generate warnings from kldxref(8) during the installkernel step. These warnings are harmless and can be ignored.
[20080307] The crypto(4) driver, which is required for IPsec functionality, has severe problems on FreeBSD/powerpc (a kernel with device crypto included in its configuration will be non-functional).
4 Late-Breaking News and Corrections
[20080229] The FreeBSD 7.0-RELEASE release documentation (release notes, hardware notes, and so forth) all contained a note that users of FreeBSD 7-STABLE should be subscribed to the freebsd-current mailing list. This note should not have appeared.
[20080229] The release notes gave an incorrect version number for KDE. The correct version number is 3.5.8.
