Git 2.21 Release Notes
======================
Backward Compatibility Notes
----------------------------
* Historically, the "-m" (mainline) option can only be used for "git
cherry-pick" and "git revert" when working with a merge commit.
This version of Git no longer warns or errors out when working with
a single-parent commit, as long as the argument to the "-m" option
is 1 (i.e. it has only one parent, and the request is to pick or
revert relative to that first parent). Scripts that relied on the
behaviour may get broken with this change.
Updates since v2.20
-------------------
UI, Workflows & Features
* The "http.version" configuration variable can be used with recent
enough versions of cURL library to force the version of HTTP used
to talk when fetching and pushing.
* Small fixes and features for fast-export and fast-import, mostly on
the fast-export side has been made.
* "git push $there $src:$dst" rejects when $dst is not a fully
qualified refname and it is not clear what the end user meant. The
codepath has been taught to give a clearer error message, and also
guess where the push should go by taking the type of the pushed
object into account (e.g. a tag object would want to go under
refs/tags/).
* "git checkout [<tree-ish>] path..." learned to report the number of
paths that have been checked out of the index or the tree-ish,
which gives it the same degree of noisy-ness as the case in which
the command checks out a branch. "git checkout -m <pathspec>" to
undo conflict resolution gives a similar message.
* "git quiltimport" learned "--keep-non-patch" option.
* "git worktree remove" and "git worktree move" refused to work when
there is a submodule involved. This has been loosened to ignore
uninitialized submodules.
* "git cherry-pick -m1" was forbidden when picking a non-merge
commit, even though there _is_ parent number 1 for such a commit.
This was done to avoid mistakes back when "cherry-pick" was about
picking a single commit, but is no longer useful with "cherry-pick"
that can pick a range of commits. Now the "-m$num" option is
allowed when picking any commit, as long as $num names an existing
parent of the commit.
* Update "git multimail" from the upstream.
* "git p4" update.
* The "--format=<placeholder>" option of for-each-ref, branch and tag
learned to show a few more traits of objects that can be learned by
the object_info API.
* "git rebase -i" learned to re-execute a command given with 'exec'
to run after it failed the last time.
* "git diff --color-moved-ws" updates.
* Custom userformat "log --format" learned %S atom that stands for
the tip the traversal reached the commit from, i.e. --source.
* "git instaweb" learned to drive http.server that comes with
"batteries included" Python installation (both Python2 & 3).
* A new encoding UTF-16LE-BOM has been invented to force encoding to
UTF-16 with BOM in little endian byte order, which cannot be directly
generated by using iconv.
* A new date format "--date=human" that morphs its output depending
on how far the time is from the current time has been introduced.
"--date=auto:human" can be used to use this new format (or any
existing format) when the output is going to the pager or to the
terminal, and otherwise the default format.
Performance, Internal Implementation, Development Support etc.
* Code clean-up with optimization for the codepath that checks
(non-)existence of loose objects.
* More codepaths have become aware of working with in-core repository
instances other than the default "the_repository".
* The "strncat()" function is now among the banned functions.
* Portability updates for the HPE NonStop platform.
* Earlier we added "-Wformat-security" to developer builds, assuming
that "-Wall" (which includes "-Wformat" which in turn is required
to use "-Wformat-security") is always in effect. This is not true
when config.mak.autogen is in use, unfortunately. This has been
fixed by unconditionally adding "-Wall" to developer builds.
* The loose object cache used to optimize existence look-up has been
updated.
* Flaky tests can now be repeatedly run under load with the
"--stress" option.
* Documentation/Makefile is getting prepared for manpage
localization.
* "git fetch-pack" now can talk the version 2 protocol.
* sha-256 hash has been added and plumbed through the code to allow
building Git with the "NewHash".
* Debugging help for http transport.
* "git fetch --deepen=<more>" has been corrected to work over v2
protocol.
* The code to walk tree objects has been taught that we may be
working with object names that are not computed with SHA-1.
* The in-core repository instances are passed through more codepaths.
* Update the protocol message specification to allow only the limited
use of scaled quantities. This is to ensure potential compatibility
issues will not get out of hand.
* Micro-optimize the code that prepares commit objects to be walked
by "git rev-list" when the commit-graph is available.
* "git fetch" and "git upload-pack" learned to send all exchanges over
the sideband channel while talking the v2 protocol.
* The codepath to write out commit-graph has been optimized by
following the usual pattern of visiting objects in in-pack order.
* The codepath to show progress meter while writing out commit-graph
file has been improved.
* Cocci rules have been updated to encourage use of strbuf_addbuf().
* "git rebase --merge" has been reimplemented by reusing the internal
machinery used for "git rebase -i".
* More code in "git bisect" has been rewritten in C.
* Instead of going through "git-rebase--am" scriptlet to use the "am"
backend, the built-in version of "git rebase" learned to drive the
"am" backend directly.
* The assumption to work on the single "in-core index" instance has
been reduced from the library-ish part of the codebase.
* The test lint learned to catch non-portable "sed" options.
* "git pack-objects" learned another algorithm to compute the set of
objects to send, that trades the resulting packfile off to save
traversal cost to favor small pushes.
* The travis CI scripts have been corrected to build Git with the
compiler(s) of our choice.
* "git submodule update" learned to abort early when core.worktree
for the submodule is not set correctly to prevent spreading damage.
* Test suite has been adjusted to run on Azure Pipeline.
* Running "Documentation/doc-diff x" from anywhere other than the
top-level of the working tree did not show the usage string
correctly, which has been fixed.
* Use of the sparse tool got easier to customize from the command
line to help developers.
* A new target "coverage-prove" to run the coverage test under
"prove" has been added.
* A flakey "p4" test has been removed.
* The code and tests assume that the system supplied iconv() would
always use BOM in its output when asked to encode to UTF-16 (or
UTF-32), but apparently some implementations output big-endian
without BOM. A compile-time knob has been added to help such
systems (e.g. NonStop) to add BOM to the output to increase
portability.
Fixes since v2.20
-----------------
* Updates for corner cases in merge-recursive.
(merge cc4cb0902c en/merge-path-collision later to maint).
* "git checkout frotz" (without any double-dash) avoids ambiguity by
making sure 'frotz' cannot be interpreted as a revision and as a
path at the same time. This safety has been updated to check also
a unique remote-tracking branch 'frotz' in a remote, when dwimming
to create a local branch 'frotz' out of a remote-tracking branch
'frotz' from a remote.
(merge be4908f103 nd/checkout-dwim-fix later to maint).
* Refspecs configured with "git -c var=val clone" did not propagate
to the resulting repository, which has been corrected.
(merge 7eae4a3ac4 sg/clone-initial-fetch-configuration later to maint).
* A properly configured username/email is required under
user.useConfigOnly in order to create commits; now "git stash"
(even though it creates commit objects to represent stash entries)
command is exempt from the requirement.
(merge 3bc2111fc2 sd/stash-wo-user-name later to maint).
* The http-backend CGI process did not correctly clean up the child
processes it spawns to run upload-pack etc. when it dies itself,
which has been corrected.
(merge 02818a98d7 mk/http-backend-kill-children-before-exit later to maint).
* "git rev-list --exclude-promisor-objects" had to take an object
that does not exist locally (and is lazily available) from the
command line without barfing, but the code dereferenced NULL.
(merge 4cf67869b2 md/list-lazy-objects-fix later to maint).
* The traversal over tree objects has learned to honor
":(attr:label)" pathspec match, which has been implemented only for
enumerating paths on the filesystem.
(merge 5a0b97b34c nd/attr-pathspec-in-tree-walk later to maint).
* BSD port updates.
(merge 4e3ecbd439 cb/openbsd-allows-reading-directory later to maint).
(merge b6bdc2a0f5 cb/t5004-empty-tar-archive-fix later to maint).
(merge 82cbc8cde2 cb/test-lint-cp-a later to maint).
* Lines that begin with a certain keyword that come over the wire, as
well as lines that consist only of one of these keywords, ought to
be painted in color for easier eyeballing, but the latter was
broken ever since the feature was introduced in 2.19, which has
been corrected.
(merge 1f67290450 hn/highlight-sideband-keywords later to maint).
* "git log -G<regex>" looked for a hunk in the "git log -p" patch
output that contained a string that matches the given pattern.
Optimize this code to ignore binary files, which by default will
not show any hunk that would match any pattern (unless textconv or
the --text option is in effect, that is).
(merge e0e7cb8080 tb/log-G-binary later to maint).
* "git submodule update" ought to use a single job unless asked, but
by mistake used multiple jobs, which has been fixed.
(merge e3a9d1aca9 sb/submodule-fetchjobs-default-to-one later to maint).
* "git stripspace" should be usable outside a git repository, but
under the "-s" or "-c" mode, it didn't.
(merge 957da75802 jn/stripspace-wo-repository later to maint).
* Some of the documentation pages formatted incorrectly with
Asciidoctor, which have been fixed.
(merge b62eb1d2f4 ma/asciidoctor later to maint).
* The core.worktree setting in a submodule repository should not be
pointing at a directory when the submodule loses its working tree
(e.g. getting deinit'ed), but the code did not properly maintain
this invariant.
* With zsh, "git cmd path<TAB>" was completed to "git cmd path name"
when the completed path has a special character like SP in it,
without any attempt to keep "path name" a single filename. This
has been fixed to complete it to "git cmd path\ name" just like
Bash completion does.
* The test suite tried to see if it is run under bash, but the check
itself failed under some other implementations of shell (notably
under NetBSD). This has been corrected.
(merge 54ea72f09c sg/test-bash-version-fix later to maint).
* "git gc" and "git repack" did not close the open packfiles that
they found unneeded before removing them, which didn't work on a
platform incapable of removing an open file. This has been
corrected.
(merge 5bdece0d70 js/gc-repack-close-before-remove later to maint).
* The code to drive GIT_EXTERNAL_DIFF command relied on the string
returned from getenv() to be non-volatile, which is not true, that
has been corrected.
(merge 6776a84dae kg/external-diff-save-env later to maint).
* There were many places the code relied on the string returned from
getenv() to be non-volatile, which is not true, that have been
corrected.
(merge 0da0e9268b jk/save-getenv-result later to maint).
* The v2 upload-pack protocol implementation failed to honor
hidden-ref configuration, which has been corrected.
(merge e20b4192a3 jk/proto-v2-hidden-refs-fix later to maint).
* "git fetch --recurse-submodules" may not fetch the necessary commit
that is bound to the superproject, which is getting corrected.
(merge be76c21282 sb/submodule-recursive-fetch-gets-the-tip later to maint).
* "git rebase" internally runs "checkout" to switch between branches,
and the command used to call the post-checkout hook, but the
reimplementation stopped doing so, which is getting fixed.
* "git add -e" got confused when the change it wants to let the user
edit is smaller than the previous change that was left over in a
temporary file.
(merge fa6f225e01 js/add-e-clear-patch-before-stating later to maint).
* "git p4" failed to update a shelved change when there were moved
files, which has been corrected.
(merge 7a10946ab9 ld/git-p4-shelve-update-fix later to maint).
* The codepath to read from the commit-graph file attempted to read
past the end of it when the file's table-of-contents was corrupt.
* The compat/obstack code had casts that -Wcast-function-type
compilation option found questionable.
(merge 764473d257 sg/obstack-cast-function-type-fix later to maint).
* An obvious typo in an assertion error message has been fixed.
(merge 3c27e2e059 cc/test-ref-store-typofix later to maint).
* In Git for Windows, "git clone \\server\share\path" etc. that uses
UNC paths from command line had bad interaction with its shell
emulation.
* "git add --ignore-errors" did not work as advertised and instead
worked as an unintended synonym for "git add --renormalize", which
has been fixed.
(merge e2c2a37545 jk/add-ignore-errors-bit-assignment-fix later to maint).
* On a case-insensitive filesystem, we failed to compare the part of
the path that is above the worktree directory in an absolute
pathname, which has been corrected.
* Asking "git check-attr" about a macro (e.g. "binary") on a specific
path did not work correctly, even though "git check-attr -a" listed
such a macro correctly. This has been corrected.
(merge 7b95849be4 jk/attr-macro-fix later to maint).
* "git pack-objects" incorrectly used uninitialized mutex, which has
been corrected.
(merge edb673cf10 ph/pack-objects-mutex-fix later to maint).
* "git checkout -b <new> [HEAD]" to create a new branch from the
current commit and check it out ought to be a no-op in the index
and the working tree in normal cases, but there are corner cases
that do require updates to the index and the working tree. Running
it immediately after "git clone --no-checkout" is one of these
cases that an earlier optimization kicked in incorrectly, which has
been fixed.
(merge 8424bfd45b bp/checkout-new-branch-optim later to maint).
* "git diff --color-moved --cc --stat -p" did not work well due to
funny interaction between a bug in color-moved and the rest, which
has been fixed.
(merge dac03b5518 jk/diff-cc-stat-fixes later to maint).
* When GIT_SEQUENCE_EDITOR is set, the command was incorrectly
started when modes of "git rebase" that implicitly uses the
machinery for the interactive rebase are run, which has been
corrected.
(merge 891d4a0313 pw/no-editor-in-rebase-i-implicit later to maint).
* The commit-graph facility did not work when in-core objects that
are promoted from unknown type to commit (e.g. a commit that is
accessed via a tag that refers to it) were involved, which has been
corrected.
(merge 4468d4435c sg/object-as-type-commit-graph-fix later to maint).
* "git fetch" output cleanup.
(merge dc40b24df4 nd/fetch-compact-update later to maint).
* "git cat-file --batch" reported a dangling symbolic link by
mistake, when it wanted to report that a given name is ambiguous.
* Documentation around core.crlf has been updated.
(merge c9446f0504 jk/autocrlf-overrides-eol-doc later to maint).
* The documentation of "git commit-tree" said that the command
understands "--gpg-sign" in addition to "-S", but the command line
parser did not know about the longhand, which has been corrected.
* "git rebase -x $cmd" did not reject multi-line command, even though
the command is incapable of handling such a command. It now is
rejected upfront.
(merge c762aada1a pw/rebase-x-sanity-check later to maint).
* Output from "git help" was not correctly aligned, which has been
fixed.
(merge 6195a76da4 nd/help-align-command-desc later to maint).
* The "git submodule summary" subcommand showed shortened commit
object names by mechanically truncating them at 7-hexdigit, which
has been improved to let "rev-parse --short" scale the length of
the abbreviation with the size of the repository.
(merge 0586a438f6 sh/submodule-summary-abbrev-fix later to maint).
* The way the OSX build jobs updates its build environment used the
"--quiet" option to "brew update" command, but it wasn't all that
quiet to be useful. The use of the option has been replaced with
an explicit redirection to the /dev/null (which incidentally would
have worked around a breakage by recent updates to homebrew, which
has fixed itself already).
(merge a1ccaedd62 sg/travis-osx-brew-breakage-workaround later to maint).
* "git --work-tree=$there --git-dir=$here describe --dirty" did not
work correctly as it did not pay attention to the location of the
worktree specified by the user by mistake, which has been
corrected.
(merge c801170b0c ss/describe-dirty-in-the-right-directory later to maint).
* "git fetch" over protocol v2 that needs to make a second connection
to backfill tags did not clear a variable that holds shallow
repository information correctly, leading to an access of freed
piece of memory.
* Some errors from the other side coming over smart HTTP transport
were not noticed, which has been corrected.
* Code cleanup, docfix, build fix, etc.

0.11.0 (released 2019-02-24)
============================
Backwards Compatibility Nodes
-----------------------------
* ZstdDecompressor.read() now allows reading sizes of -1 or 0
and defaults to -1, per the documented behavior of
io.RawIOBase.read(). Previously, we required an argument that was
a positive value.
* The readline(), readlines(), __iter__, and __next__ methods
of ZstdDecompressionReader() now raise io.UnsupportedOperation
instead of NotImplementedError.
* ZstdDecompressor.stream_reader() now accepts a read_across_frames
argument. The default value will likely be changed in a future release
and consumers are advised to pass the argument to avoid unwanted change
of behavior in the future.
* setup.py now always disables the CFFI backend if the installed
CFFI package does not meet the minimum version requirements. Before, it was
possible for the CFFI backend to be generated and a run-time error to
occur.
* In the CFFI backend, CompressionReader and DecompressionReader
were renamed to ZstdCompressionReader and ZstdDecompressionReader,
respectively so naming is identical to the C extension. This should have
no meaningful end-user impact, as instances aren't meant to be
constructed directly.
* ZstdDecompressor.stream_writer() now accepts a write_return_read
argument to control whether write() returns the number of bytes
read from the source / written to the decompressor. It defaults to off,
which preserves the existing behavior of returning the number of bytes
emitted from the decompressor. The default will change in a future release
so behavior aligns with the specified behavior of io.RawIOBase.
* ZstdDecompressionWriter.__exit__ now calls self.close(). This
will result in that stream plus the underlying stream being closed as
well. If this behavior is not desirable, do not use instances as
context managers.
* ZstdCompressor.stream_writer() now accepts a write_return_read
argument to control whether write() returns the number of bytes read
from the source / written to the compressor. It defaults to off, which
preserves the existing behavior of returning the number of bytes emitted
from the compressor. The default will change in a future release so
behavior aligns with the specified behavior of io.RawIOBase.
* ZstdCompressionWriter.__exit__ now calls self.close(). This will
result in that stream plus any underlying stream being closed as well. If
this behavior is not desirable, do not use instances as context managers.
* ZstdDecompressionWriter no longer requires being used as a context
manager.
* ZstdCompressionWriter no longer requires being used as a context
manager.
* The overlap_size_log attribute on CompressionParameters instances
has been deprecated and will be removed in a future release. The
overlap_log attribute should be used instead.
* The overlap_size_log argument to CompressionParameters has been
deprecated and will be removed in a future release. The overlap_log
argument should be used instead.
* The ldm_hash_every_log attribute on CompressionParameters instances
has been deprecated and will be removed in a future release. The
ldm_hash_rate_log attribute should be used instead.
* The ldm_hash_every_log argument to CompressionParameters has been
deprecated and will be removed in a future release. The ldm_hash_rate_log
argument should be used instead.
* The compression_strategy argument to CompressionParameters has been
deprecated and will be removed in a future release. The strategy
argument should be used instead.
* The SEARCHLENGTH_MIN and SEARCHLENGTH_MAX constants are deprecated
and will be removed in a future release. Use MINMATCH_MIN and
MINMATCH_MAX instead.
* The zstd_cffi module has been renamed to zstandard.cffi. As had
been documented in the README file since the 0.9.0 release, the
module should not be imported directly at its new location. Instead,
import zstandard to cause an appropriate backend module to be loaded
automatically.
Bug Fixes
---------
* CFFI backend could encounter a failure when sending an empty chunk into
ZstdDecompressionObj.decompress(). The issue has been fixed.
* CFFI backend could encounter an error when calling
ZstdDecompressionReader.read() if there was data remaining in an
internal buffer. The issue has been fixed.
Changes
-------
* ZstDecompressionObj.decompress() now properly handles empty inputs in
the CFFI backend.
* ZstdCompressionReader now implements read1() and readinto1().
These are part of the io.BufferedIOBase interface.
* ZstdCompressionReader has gained a readinto(b) method for reading
compressed output into an existing buffer.
* ZstdCompressionReader.read() now defaults to size=-1 and accepts
read sizes of -1 and 0. The new behavior aligns with the documented
behavior of io.RawIOBase.
* ZstdCompressionReader now implements readall(). Previously, this
method raised NotImplementedError.
* ZstdDecompressionReader now implements read1() and readinto1().
These are part of the io.BufferedIOBase interface.
* ZstdDecompressionReader.read() now defaults to size=-1 and accepts
read sizes of -1 and 0. The new behavior aligns with the documented
behavior of io.RawIOBase.
* ZstdDecompressionReader() now implements readall(). Previously, this
method raised NotImplementedError.
* The readline(), readlines(), __iter__, and __next__ methods
of ZstdDecompressionReader() now raise io.UnsupportedOperation
instead of NotImplementedError. This reflects a decision to never
implement text-based I/O on (de)compressors and keep the low-level API
operating in the binary domain.
* README.rst now documented how to achieve linewise iteration using
an io.TextIOWrapper with a ZstdDecompressionReader.
* ZstdDecompressionReader has gained a readinto(b) method for
reading decompressed output into an existing buffer. This allows chaining
to an io.TextIOWrapper on Python 3 without using an io.BufferedReader.
* ZstdDecompressor.stream_reader() now accepts a read_across_frames
argument to control behavior when the input data has multiple zstd
*frames*. When False (the default for backwards compatibility), a
read() will stop when the end of a zstd *frame* is encountered. When
True, read() can potentially return data spanning multiple zstd
*frames*. The default will likely be changed to True in a future
release.
* setup.py now performs CFFI version sniffing and disables the CFFI
backend if CFFI is too old. Previously, we only used install_requires
to enforce the CFFI version and not all build modes would properly enforce
the minimum CFFI version.
* CFFI's ZstdDecompressionReader.read() now properly handles data
remaining in any internal buffer. Before, repeated read() could
result in *random* errors.
* Upgraded various Python packages in CI environment.
* Upgrade to hypothesis 4.5.11.
* In the CFFI backend, CompressionReader and DecompressionReader
were renamed to ZstdCompressionReader and ZstdDecompressionReader,
respectively.
* ZstdDecompressor.stream_writer() now accepts a write_return_read
argument to control whether write() returns the number of bytes read
from the source. It defaults to False to preserve backwards
compatibility.
* ZstdDecompressor.stream_writer() now implements the io.RawIOBase
interface and behaves as a proper stream object.
* ZstdCompressor.stream_writer() now accepts a write_return_read
argument to control whether write() returns the number of bytes read
from the source. It defaults to False to preserve backwards
compatibility.
* ZstdCompressionWriter now implements the io.RawIOBase interface and
behaves as a proper stream object. close() will now close the stream
and the underlying stream (if possible). __exit__ will now call
close(). Methods like writable() and fileno() are implemented.
* ZstdDecompressionWriter no longer must be used as a context manager.
* ZstdCompressionWriter no longer must be used as a context manager.
When not using as a context manager, it is important to call
flush(FRAME_FRAME) or the compression stream won't be properly
terminated and decoders may complain about malformed input.
* ZstdCompressionWriter.flush() (what is returned from
ZstdCompressor.stream_writer()) now accepts an argument controlling the
flush behavior. Its value can be one of the new constants
FLUSH_BLOCK or FLUSH_FRAME.
* ZstdDecompressionObj instances now have a flush([length=None]) method.
This provides parity with standard library equivalent types.
* CompressionParameters no longer redundantly store individual compression
parameters on each instance. Instead, compression parameters are stored inside
the underlying ZSTD_CCtx_params instance. Attributes for obtaining
parameters are now properties rather than instance variables.
* Exposed the STRATEGY_BTULTRA2 constant.
* CompressionParameters instances now expose an overlap_log attribute.
This behaves identically to the overlap_size_log attribute.
* CompressionParameters() now accepts an overlap_log argument that
behaves identically to the overlap_size_log argument. An error will be
raised if both arguments are specified.
* CompressionParameters instances now expose an ldm_hash_rate_log
attribute. This behaves identically to the ldm_hash_every_log attribute.
* CompressionParameters() now accepts a ldm_hash_rate_log argument that
behaves identically to the ldm_hash_every_log argument. An error will be
raised if both arguments are specified.
* CompressionParameters() now accepts a strategy argument that behaves
identically to the compression_strategy argument. An error will be raised
if both arguments are specified.
* The MINMATCH_MIN and MINMATCH_MAX constants were added. They are
semantically equivalent to the old SEARCHLENGTH_MIN and
SEARCHLENGTH_MAX constants.
* Bundled zstandard library upgraded from 1.3.7 to 1.3.8.
* setup.py denotes support for Python 3.7 (Python 3.7 was supported and
tested in the 0.10 release).
* zstd_cffi module has been renamed to zstandard.cffi.
* ZstdCompressor.stream_writer() now reuses a buffer in order to avoid
allocating a new buffer for every operation. This should result in faster
performance in cases where write() or flush() are being called
frequently.
* Bundled zstandard library upgraded from 1.3.6 to 1.3.7.
* Add missing variables to save states
* Sync some bug fixes from 0.9.39.2:
- Fixed several off-by-1 bugs in address to ROM data translation
- Fixed an old Z80 emulation bug with interrupt handling.
* Softpatching support
fping 4.2:
New features
* New option -x / --reachable to check if the number of reachable hosts is >= a certain number. Useful for example to implement connectivity-checks
Bugfixes and other changes
* Allow decimal numbers for '-t', '-i', '-p', and '-Q'
* Fix build with --disable-ipv6
* Fix hang with '-6', with ipv6 kernel module, but not loaded
* Assume '-6' if the binary is named 'fping6' (this is mostly for special embedded-distro use cases, and not meant to be used generally in place of compiling IPv6-only binary or using '-6'
* Get rid of warning "timeout (-t) value larger than period (-p) produces unexpected results"
SQLite Release 3.27.2:
Fix a bug in the IN operator that was introduced by an attempted optimization in version 3.27.0.
Fix a bug causing a crash when a window function is misused.
Fix various documentation typos
## RMagick 3.0.0
Breaking Changes:
- Drop support for Ruby < 2.3.
- Drop support for ImageMagick < 6.8.
- Raise error when `nil` or empty string are passed to `Image.read`. (#351)

- Add feature `Image#channel_entropy` (#300)
- Many quality of life improvements in the codebase.
Bug Fixes:
- Many memory leaks fixed!
- Fix `LoadError` on Windows. (#315)

Version 1.1.1
-------------
Released 2019-02-23
- Fix segfault when ``__html__`` method raises an exception when using
the C speedups. The exception is now propagated correctly. (#109)
This is based on a git checkout from a couple days ago; not completely
sure about the version number.
The Makefile now contains a short how-to for updating this package.
Many thanks for the www/firefox60 patches!
Use at your own risk!
Survives basic browsing and check.torproject.org claims it connects via tor.
Changes: too many to document.
pkgsrc changes:
- Rename swi-prolog to swipl to follow upstream nomenclature
- Add all main packages (except X11) to swi-prolog-lite.
After CMake migration in order to generate the documentation and being able
to use it (e.g. via help/2) it is needed to add basic, archive, ssl and term
packages.
All X11 packages are provided by swi-prolog-packages.
- Adjust pkgsrc Makefile-s logic to upstream CMake migration:
o Uncoditionally disable not wanted packages in Makefile.common (to avoid
possible PLIST mismatches; please note that this will probably disable
tipc package on Linux!).
All other installed packages are enabled/disabled via
swi-prolog-{lite,packages,jpl} Makefile.
o Add libarchive, ossp-uuid and openssl build dependency to
swi-prolog-packages. Despite these are provided by swi-prolog-lite
they are needed as part of the build of swi-prolog-packages too.
o Remove no more needed logic to check and eventually start X server to
build documentation. Should address PR pkg/42047.
- Remove an unconditional CHECK_WRKREF_SKIP, this was needed on FreeBSD
but unfortunately it is not clear why. If this is still needed please let
me know in order to try to investigate further and address that.
- Bump API requirements to 8.0.1 in buildlink3.mk to be on the safe side
now that shared libraries are provided on all platforms.
Changes:
8.0.1
-----
Indexing on multiple arguments together, indexing inside compounds,
Mode-directed tabling, saved states using ZIP files, many deployment
enhancements. Moved build environment to CMake and removed most of
the build tool dependencies. Builds documentation along with the
binary.
Please note that this is just a short summary. Unfortunately the
complete changelog is very long, full changelog can be found at:
