4 This file documents feature changes at a very high level.
6 A '-' means that the support for that feature was removed, a '+' means that
7 the support for that feature was added, and a '*' means that the behavior
12 + native compiler support:
13 * all provided compilers and binutils generate 64-bit output by default.
14 -m32 is required for 32-bit.
15 * gcc 4.9 has been removed. gcc 6.4.0 is now the default compiler
16 /usr/bin/cc, and it is used to build userland and the bmake part of base.
17 * gcc 4.4.4 aka. illumos-gcc is provided in /opt/gcc/4.4.4/bin/gcc, and it
18 is used to build itself as well as the dmake part of base.
19 * the default compiler uses GNU binutils ld.bfd as the linker. gcc 4.4.4
20 stays with sunld for compatibility.
21 * the default compiler does not support Solaris-specific features (eg.
22 #pragma init/fini, cmn_err format checking, startfile selection from
23 values-{Xa,Xc,Xs,Xt,xpg4,xpg6} based on -std)
24 * the default compiler does not define sun/__sun/__sun___ or
25 __svr4__/__SVR4. gcc 4.4.4 still does, for compatibility reasons.
26 * __unleashed__ is automatically defined by all provided compilers.
27 - multiarch support from python removed; it's now 64-bit only
28 - /etc/log symlink & /var/adm/log directory
29 - /etc/[uw]tmpx symlink
31 - legacy accounting and reporting
32 * 32-bit libraries moved to i386 subdir of /lib and /usr/lib, and 64-bit
33 libraries moved from the amd64 subdir to the top level of /lib and /usr/lib.
34 in subdirectories not directly handled by the default ld.so configuration,
35 the old style of amd64 subdir is still (mostly) used.
36 * moved all /var/adm files to /var/log
37 * moved /var/svc/log to /var/log/svc
38 * ntp has been replaced with openntpd 6.2p3
44 - ksh93 (/sbin/sh, /bin/ksh93, /bin/rksh93) and related libraries (libast,
45 libcmd, libdll, libpp, libshell, libsum) are no more.
46 - nonstandard getgrent_r, fgetgrent_r removed from libc
47 - wordexp & wordfree removed from libc
48 - sgtty.h removed, including stty() and gtty()
49 - nightly.sh is no more; see README.md for updated build instructions
50 * removed posix.1c draft versions, and made default the standard versions, of
51 the libc functions getgrgid_r, getgrnam_r, ttyname_r, getlogin_r
52 * removed non-posix versions of the libc functions shmdt, sigwait,
53 gethostname, putmsg, putpmsg, getaddrinfo
54 + _XOPEN_SOURCE=700 and __EXTENSIONS__ are defined by default, if not
55 specified. most third-party software already uses these on Solarises in an
56 attempt to get a somewhat sane compilation environment
57 + all applications automatically use 64-bit files. using the LFS/"large file"
58 interfaces _LARGEFILE_SOURCE, _LARGEFILE64_SOURCE and _FILE_OFFSET_BITS is
60 + various improvements have been made to shorten the build time.
61 + the installer user interface has been simplified considerably.
65 - libfruraw, libnvfru, libfru, libfrureg, libfruutils
66 - libpicl, libpicltree, picld(8), etc.
69 - auditing support and libbsm
70 + ship ctfconvert & ctfmerge in /usr/bin
71 * hwdata updated to 2018.11.29
72 * tzdata updated to 2018g
74 * uname(1) returns "amd64" for -m and -p
75 * sysinfo(SI_ARCHITECTURE) returns "amd64" (or "i386" when UNAME_LEGACY is
77 * rename vnode interface's AT_* to VATTR_*
81 - hsfs-formatted boot archive support
82 - libc compat symbols: _nuname, __posix_readdir_r, __threaded
83 - binary compatibility bread/bwrite/bwrite2/getblk kernel symbols

85 - libm.so.1 (legacy libm)
86 - shcomp(1) and the ability to run "compiled" ksh93 shell scripts (shbinexec)
87 - useless ksh93 /usr/bin builtins: cd, command, history, jobs, limit,
88 print, read, type, umask, wait
90 + ship libcmdutils.so & libuutil.so compilation symlinks
91 * ship openbsd ksh as /bin/sh (/bin/ksh93, /bin/rksh93, and /sbin/sh remain
93 * convert BREAD/BWRITE/BWRITE2/GETBLK macros to bread/bwrite/bwrite2/getblk
95 * collapse driver packages into system/kernel
96 * replace ksh93 /usr/bin builtins with real programs imported from OpenBSD:
97 comm, cut, join, kill, logname, paste, rev, sleep, tee, test, uniq, wc
98 * autofs is disabled by default
99 * zoneinfo data moved from /usr/share/lib/zoneinfo to /usr/share/zoneinfo
