OpenBSD Following -current and using snapshots [FAQ Index]

Active OpenBSD development is known as the -current branch. These sources are frequently compiled into releases known as snapshots.

Aggressive changes are sometimes pushed in this branch, and complications can arise when building the latest code or upgrading from a previous point in time. Some of the steps for getting over these hurdles are explained on this page. Make sure you've read and understand how to build the system from source before using -current and the instructions below.

In general, it's far easier to use snapshots, as developers will have gone through much of the trouble for you already.

You should always use a snapshot as the starting point for running -current. This process typically consists of downloading (and verifying) the appropriate bsd.rd file from the /snapshots/ directory of your preferred mirror, booting from it, and choosing (U)pgrade at the prompt. Any installed packages should then be upgraded after booting into the new system.

Upgrading to -current by compiling your own source code is not supported.

Most of these changes will have to be performed as root.

2018/04/04 - PF_TRANS_ALTQ removed

The obsolete PF_TRANS_ALTQ has been removed from net/pfvar.h. Several userland programs will need to be recompiled together with the kernel. Using a snapshot is highly recommended. To update from source, the following steps are needed:
  1. Build and install the kernel but do NOT reboot.
  2. Rebuild the affected programs: 
    # cd /usr/src && make includes
# cd /usr/src/sbin/pfctl && make clean && make && make install
# cd /usr/src/usr.sbin/authpf && make clean && make && make install
# cd /usr/src/usr.sbin/ftp-proxy && make clean && make && make install
# cd /usr/src/usr.sbin/relayd && make clean && make && make install
# cd /usr/src/usr.sbin/tftp-proxy && make clean && make && make install
  3. Reboot.

2018/04/11 - meaning of listen on * port 80 changed in httpd(8)

The meaning of listen on * port 80 changed from "listen on all IPv4 addresses" to "listen on all IPv4 and all IPv6 addresses". If listen on * port 80 is present, listen on :: port 80 needs to be removed. For example, 
listen on * port 80
listen on :: port 80
must be changed to: 
listen on * port 80

2018/04/20 - [packages] security/kc storage format change

The storage format of keychains has changed in a backward incompatible way. Dump all your keychains to xml before updating: 
$ kc -k ~/.kc/default.kcd
Password:
<example_chain% > dump kcdump
Dump OK
<example_chain% > quit
After updating follow the instructions in /usr/local/share/doc/kc/Changelog.
