* Builds without AUTH now compile.
* Builds without IPv4LL now compile.
Thanks to Joerg Sonnenberger.
* BPF no longer uses a variable length buffer for stack protector.
* Minor documentation fix for duid file location.
Thanks to Peter Colberg.
* source file locations reworked:
dhcpcd source is in src
dhcpcd hooks are in hooks
compat is in compat
* README split into README.md and BUILDING.md
* internal routing is now protocol agnostic
* avoid using __packed and use compile time asserts instead
* addresses some alignment issues
* disable some ARP code on kernels which support RFC5227
* BSD IPv6 kernel settings are now updated to reflect dhcpcd config
* custom logger has been removed, syslog handles everything
as such, the --logfile option has been removed as well.
If you need better/earlier logging, get a better syslogger!
* distinfo and signed distinfo files are now available alongside
release taraballs from this point onwards
* default DBDIR has changed from /var/db to /var/db/dhcpcd
* /etc/dhcpcd.duid moves to DBDIR/duid
* /etc/dhcpcd.secret moves to DBDIR/secret
* lease file names have dhcpcd removed from them as they are now
inside a directory of the same name
* fixed issues with reject routes not working on some platforms
* improved nl80211 support on Linux for working out the SSID
* no longer request NTP by default in dhcpcd.conf
* BPF filtering vastly improved so dhcpcd only wake up on
ARP or DHCP packets destined for it
* support for MUD URL (draft-ietf-opsawg-mud-05)
* if the kernel isn't doing DAD, don't insist on waiting for it
to actually do it
* fix a potential crash where the DHCP or ARP states could be
freed before the packet processing loop naturally breaks
* removed gateway and nogateway options
(these can be controlled by the nooption directive which
works for more than just gateways)
* removed ipv6ra_own and ipv6ra_own_default options
(these can be controled by the ipv6rs/noipv6rs directive)
* fix a crash receiving SIGUSR1
Remove hardcoded argument to .Os
Remove extra arguments to .Dt
The extra arguments to .Dt were being parsed as the machine architecture for
the man page by mandoc parser, because of which the output of apropos(1) would show
it as file/ntp.keys(5). Same problem exists with other ntp man pages as well.
Committing with approval from Christos, we will investigate and fix the problems
in the source when regenerating the man pages next time.
restore ABI compatibility with previous releases for ieeefp.h on sh3.
add namespace.h protection for all the fenv interfaces.
use MKSOFTFLOAT on sh3 instead of assuming softfloat.
standardize on comparing MKSOFTFLOAT with "no".
remove the arm-specific softfloat fenv code (which also had several bugs).
fix logic errors in the arm hardfloat feraiseexcept() and feupdateenv().
Summary of changes in tzdata2017b (2017-03-17 07:30:38 -0700):
Haiti resumed observance of DST in 2017 (on Mar 12)
Liberia changed from -004430 to +00 on 1972-01-07, not 1972-05-01.
Use "MMT" to abbreviate Liberia's time zone before 1972,
as "-004430" (tzdata2016a) is one byte over the POSIX limit.
--- MAJOR NEW FEATURES ---
* apropos(1): Reimplement complete semantic search functionality
without the dependency on SQLite3, using only POSIX APIs.
This comes with a completely new mandoc.db(5) file format.
* man(1): Support more than one tag entry for the same search term,
plus some minor improvements to the less(1) :t support.
* -Thtml: Use real macro names for CSS classes.
Systematic cleanup of and many improvements to mandoc.css.
* -Thtml: Produce human readable HTML code by using indentation
and better line breaks. Improve various HTML elements,
and trim several useless ones.
* New catman(8) utility, still somewhat experimental.
* Now includes a portable version of the OpenBSD mandoc regression
suite, see regress/regress.pl.1 for details.
--- REMOVED FUNCTIONALITY ---
* Operating systems that don't provide mmap(3) are no longer supported.
* Drop support for manpath(1). Even if your system has manpath(1),
it is simpler to use MANPATH_DEFAULT in configure.local for
operating system defaults, man.conf(5) for machine-specific
modifications, and ${MANPATH}, -m, and -M for user preferences
than to bother with the complexity of manpath(1).
* makewhatis(8) -p: No longer warn about missing MLINKS since these
are no longer needed for anything.
--- MINOR NEW FEATURES ---
* mdoc(7): Warn about invalid punctuation and content below NAME.
* mdoc(7): Warn about .Xr lacking the second argument (section).
* mdoc(7): Warn about violations of the rule "new sentence, new line".
* roff(7): Warn about trailing whitespace at the end of comments.
* mdoc(7): Improve rendering of double quotes.
* mdoc(7): Always do text production in the validator, never in the
formatters. Cleaner, simpler, shorter, helps NetBSD apropos(1)
and also makes -Ttree output more useful.
* -Ttree: Show metadata and some additional node flags.
New -Onoval output option to show the unvalidated tree.
--- RELIABILITY BUGFIXES ---
* man(1): Make "man -l" work with standard input from a pipe or file,
as long as standard output is a terminal.
* man(7): Fix out of bounds read access if a text node immediately
preceded the first .SH header.
* mdoc(7): Fix out of bounds read access for .Bl without a type
but with a width.
* mdoc(7): Fix out of bounds read access for .Bl -column starting
with a tab character instead of a child .It macro.
* mdoc(7): Fix syntax tree corruption leading to segfaults caused
by stray block end macros in nested blocks of mismatching type.
* man(1): Fix NULL dereference when the first of multiple pages
shown was preformatted.
* mdoc(7): Fix syntax tree corruption leading to NULL dereference
caused by partial implicit macros inside .Bl -column table cells.
* mdoc(7): Fix syntax tree corruption leading to NULL dereference
for macro sequences like .Bl .Bl .It Bo .El .It.
* mdoc(7): Fix syntax tree corruption leading to NULL dereference
caused by .Ta following a nested .Bl -column breaking another block.
* mdoc(7): Fix syntax tree corruption sometimes leading to NULL
dereference caused by indirectly broken .Nd or .Nm blocks.
* mdoc(7) -Thtml: Fix a NULL dereference for .Bl -column with 0 columns.
* mdoc(7): Fix NULL dereference in some specific cases of a
block-end macro calling another block-end macro.
* mdoc(7): Fix NULL dereference if the only child of the head
of the first .Sh was an empty in-line macro.
* eqn(7): Fix NULL dereference in the terminal formatter
for empty matrices and empty square roots.
* mdoc(7): Fix an assertion failure for a .Bd without a type that
breaks another block.
* mdoc(7): Fix an assertion failure that happened for some .Bl -column
lists containing a column width of "-4n", "-3n", or "-2n".
* mdoc(7): Fix an assertion failure caused by .Bl -column without .It
but containing eqn(7) or tbl(7) code.
* roff(7): Fix an assertion failure caused by \z\[u00FF] with -Tps/-Tpdf.
* roff(7): Fix an assertion failures caused by whitespace inside \o''
(overstrike) sequences.
* -Thtml: Fix an assertion failure caused by -Oman or -Oincludes of
excessive length.
--- PORTABILITY IMPROVEMENTS ---
* man(1): Do not mix stdio narrow and wide stream orientation
on stdout, which could cause output corruption on glibc.
* mandoc(1): Autodetect a suitable locale for -Tutf8 mode.
* ./configure: Autodetect whether PATH_MAX and O_DIRECTORY are defined.
* ./configure: Autodetect if nanosleep(3) needs -lrt.
* ./configure: Provide an ${LN} configuration variable.
* ./configure: Put compiler arguments that may contain -l at the end.
--- MINOR BUGFIXES ---
* mdoc(7): Fix SYNOPSIS output if the first child of .Nm is a macro.
* mdoc(7) -Thtml: Improve formatting of .Bl -tag with short tags.
* man(7) -Thtml: Preserve whitespace in .nf (nofill) mode.
* mandoc(1): Error out on invalid output options on the command line.
--- STRUCTURAL CHANGES, no functional change ---
* Redesign part of the mandoc_html(3) interfaces, making them much
easier to use and reducing the amount of code by a few hundred lines.

Approximately 25% better performance from the R-Tree extension.
Uses compiler built-ins (ex: __builtin_bswap32() or _byteswap_ulong()) for byteswapping when available.
Uses the sqlite3_blob key/value access object instead of SQL for pulling content out of R-Tree nodes
Other miscellaneous enhancements such as loop unrolling.
Add the SQLITE_DEFAULT_LOOKASIDE compile-time option.
Increase the default lookaside size from 512,125 to 1200,100 as this provides better performance while only adding 56KB of extra memory per connection. Memory-sensitive applications can restore the old default at compile-time, start-time, or run-time.
Use compiler built-ins __builtin_sub_overflow(), __builtin_add_overflow(), and __builtin_mul_overflow() when available. (All compiler built-ins can be omitted with the SQLITE_DISABLE_INTRINSIC compile-time option.)
Added the SQLITE_ENABLE_NULL_TRIM compile-time option, which can result in significantly smaller database files for some applications, at the risk of being incompatible with older versions of SQLite.
Change SQLITE_DEFAULT_PCACHE_INITSZ from 100 to 20, for improved performance.
Added the SQLITE_UINT64_TYPE compile-time option as an analog to SQLITE_INT64_TYPE.
Perform some UPDATE operations in a single pass instead of in two passes.
Enhance the session extension to support WITHOUT ROWID tables.
Fixed performance problems and potential stack overflows when creating views from multi-row VALUES clauses with hundreds of thousands of rows.
Added the sha1.c extension.
In the command-line shell, enhance the ".mode" command so that it restores the default column and row separators for modes "line", "list", "column", and "tcl".
Enhance the SQLITE_DIRECT_OVERFLOW_READ option so that it works in WAL mode as long as the pages being read are not in the WAL file.
Enhance the LEMON parser generator so that it can store the parser object as a stack variable rather than allocating space from the heap and make use of that enhancement in the amalgamation.
Other performance improvements. Uses about 6.5% fewer CPU cycles.
Bug Fixes:
Throw an error if the ON clause of a LEFT JOIN references tables to the right of the ON clause. This is the same behavior as PostgreSQL. Formerly, SQLite silently converted the LEFT JOIN into an INNER JOIN. Fix for ticket 25e335f802dd.
Use the correct affinity for columns of automatic indexes. Ticket 7ffd1ca1d2ad4ec.
Ensure that the sqlite3_blob_reopen() interface can correctly handle short rows. Fix for ticket e6e962d6b0f06f46e.

2017-01-06 (3.16.2)
Fix the REPLACE statement for WITHOUT ROWID tables that lack secondary indexes so that it works correctly with triggers and foreign keys. This was a new bug caused by performance optimizations added in version 3.16.0. Ticket 30027b613b4
Fix the sqlite3_value_text() interface so that it correctly translates content generated by zeroblob() into a string of all 0x00 characters. This is a long-standing issue discovered after the 3.16.1 release by OSS-Fuzz
Fix the bytecode generator to deal with a subquery in the FROM clause that is itself a UNION ALL where one side of the UNION ALL is a view that contains an ORDER BY. This is a long-standing issue that was discovered after the release of 3.16.1. See ticket 190c2507.
Adjust the sqlite3_column_count() API so it more often returns the same values for PRAGMA statements as it did in prior releases, to minimize disruption to applications that might be using that interface in unexpected ways.

Uses 9% fewer CPU cycles. (See the CPU performance measurement report for details on how this performance increase was computed.)
Added experimental support for PRAGMA functions.
Added the SQLITE_DBCONFIG_NO_CKPT_ON_CLOSE option to sqlite3_db_config().
Enhance the date and time functions so that the 'unixepoch' modifier works for the full span of supported dates.
Changed the default configuration of the lookaside memory allocator from 500 slots of 128 bytes each into 125 slots of 512 bytes each.
Enhanced "WHERE x NOT NULL" partial indexes so that they are usable if the "x" column appears in a LIKE or GLOB operator.
Enhanced sqlite3_interrupt() so that it interrupts checkpoint operations that are in process.
Enhanced the LIKE and GLOB matching algorithm to be faster for cases when the pattern contains multiple wildcards.
Added the SQLITE_FCNTL_WIN32_GET_HANDLE file control opcode.
Added ".mode quote" to the command-line shell.
Added ".lint fkey-indexes" to the command-line shell.
Added the .imposter dot-command to the command-line shell.
Added the remember(V,PTR) SQL function as a loadable extension.
Rename the SQLITE_OMIT_BUILTIN_TEST compile-time option to SQLITE_UNTESTABLE to better reflect the implications of using it.
Bug Fixes:
Fix a long-standing bug in the query planner that caused incorrect results on a LEFT JOIN where the left-hand table is a subquery and the join constraint is a bare column name coming from the left-hand subquery. Ticket 2df0107b.
Correctly handle the integer literal -0x8000000000000000 in the query planner.

Added SQLITE_FCNTL_WIN32_GET_HANDLE file control opcode.
Fix the VACUUM command so that it spills excess content to disk rather than holding everything in memory, and possible causing an out-of-memory error for larger database files. This fixes an issue introduced by version 3.15.0.
Fix a case (present since 3.8.0 - 2013-08-26) where OR-connected terms in the ON clause of a LEFT JOIN might cause incorrect results. Ticket 34a579141b2c5ac.
Fix a case where the use of row values in the ON clause of a LEFT JOIN might cause incorrect results. Ticket fef4bb4bd9185ec8f.

Added support for row values.
Allow deterministic SQL functions in the WHERE clause of a partial index.
Added the "modeof=filename" URI parameter on the unix VFS
Added support for SQLITE_DBCONFIG_MAINDBNAME.
Added the ability to VACUUM an ATTACH-ed database.
Enhancements to the command-line shell:
Add the ".testcase" and ".check" dot-commands.
Added the --new option to the ".open" dot-command, causing any prior content in the database to be purged prior to opening.
Enhance the fts5vocab virtual table to handle "ORDER BY term" efficiently.
Miscellaneous micro-optimizations reduce CPU usage by more than 7% on common workloads. Most optimization in this release has been on the front-end (sqlite3_prepare_v2()).
Bug Fixes:
The multiply operator now correctly detects 64-bit integer overflow and promotes to floating point in all corner-cases. Fix for ticket 1ec41379c9c1e400.
Correct handling of columns with redundant unique indexes when those columns are used on the LHS of an IN operator. Fix for ticket 0eab1ac759.
Skip NULL entries on range queries in indexes on expressions. Fix for ticket 4baa46491212947.
Ensure that the AUTOINCREMENT counters in the sqlite_sequence table are initialized doing "Xfer Optimization" on "INSERT ... SELECT" statements. Fix for ticket 7b3328086a5c116c.
Make sure the ORDER BY LIMIT optimization (from check-in 559733b09e) works with IN operators on INTEGER PRIMARY KEYs. Fix for ticket 96c1454c

Fix commenting errors and improve the comments generated on EXPLAIN listings when the -DSQLITE_ENABLE_EXPLAIN_COMMENTS compile-time option is used.
Fix the ".read" command in the command-line shell so that it understands that its input is not interactive.
Correct affinity computations for a SELECT on the RHS of an IN operator. Fix for ticket 199df4168c.
The ORDER BY LIMIT optimization is not valid unless the inner-most IN operator loop is actually used by the query plan. Fix for ticket 0c4df46116e90f92.

2016-08-08 (3.14)
Celebrating the SQLite "# release" with a home-baked pie.
Added support for WITHOUT ROWID virtual tables.
Improved the query planner so that the OR optimization can be used on virtual tables even if one or more of the disjuncts use the LIKE, GLOB, REGEXP, MATCH operators.
Added the CSV virtual table for reading RFC 4180 formatted comma-separated value files.
Added the carray() table-valued function extension.
Enabled persistent loadable extensions using the new SQLITE_OK_LOAD_PERMANENTLY return code from the extension entry point.
Added the SQLITE_DBSTATUS_CACHE_USED_SHARED option to sqlite3_db_status().
Add the vfsstat.c loadable extension - a VFS shim that measures I/O together with an eponymous virtual table that provides access to the measurements.
Improved algorithm for running queries with both an ORDER BY and a LIMIT where only the inner-most loop naturally generates rows in the correct order.
Enhancements to Lemon parser generator, so that it generates a faster parser.
The PRAGMA compile_options command now attempts to show the version number of the compiler that generated the library.
Enhance PRAGMA table_info so that it provides information about eponymous virtual tables.
Added the "win32-none" VFS, analogous to the "unix-none" VFS, that works like the default "win32" VFS except that it ignores all file locks.
The query planner uses a full scan of a partial index instead of a full scan of the main table, in cases where that makes sense.
Allow table-valued functions to appear on the right-hand side of an IN operator.
Created the dbhash.exe command-line utility.
Added two new C-language interfaces: sqlite3_expanded_sql() and sqlite3_trace_v2(). These new interfaces subsume the functions of sqlite3_trace() and sqlite3_profile() which are now deprecated.
Added the json_quote() SQL function to the json1 extension.
Disable the authorizer callback while reparsing the schema.
Added the SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION compile-time option and turned that option on by default when building the command-line shell.
Bug Fixes:
Fix the ALTER TABLE command so that it does not corrupt descending indexes when adding a column to a legacy file format database. Ticket f68bf68513a1c15f
Fix a NULL-pointer dereference/crash that could occurs when a transitive WHERE clause references a non-existent collating sequence. Ticket e8d439c77685eca6.
Improved the cost estimation for an index scan which includes a WHERE clause that can be partially or fully evaluated using columns in the index and without having to do a table lookup. This fixes a performance regression that occurred for some obscure queries following the ORDER BY LIMIT optimization introduced in version 3.12.0.

Summary of changes in tzdata2017a (2017-02-28 00:05:36 -0800):
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia
discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST.
Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid
before 1979, to agree with tables compiled by Pere Planesas of the
National Astronomical Observatory of Spain. As a side effect,
this changes some time stamps for Africa/Ceuta before 1929, which
are probably guesswork anyway.
Ecuador observed DST from 1992-11-28 to 1993-02-05.
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as
part of the ongoing project of removing invented abbreviations.
For Alaska time from 1900 through 1967, instead of "CAT" use the
abbreviation "AST", the abbreviation commonly used at the time
(Atlantic Standard Time had not been standardized yet). Use "AWT"
and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau
before 1999 and Taiwan before 1938, and use "JST" instead of the
invented abbreviation "JCST" for Japan and Korea before 1938.
Change to database entry category
Move the Pacific/Johnston link from 'australasia' to 'backward',
since Johnston is now uninhabited.
fix the dtrace "args" variable to return correct values.
simplify the invop handlers a bit by changing the second argument
from a pointer into the stack to a pointer to the trapframe.
after rev 1.6 of m68k.md (which itself reverted a local patch that hadn't
been necessary for over a decade... see gcc bugzilla 12792).
discussed with christos and confirmed no regressions with the atf tests.
