Exim version 4.94
-----------------
JH/01 Avoid costly startup code when not strictly needed. This reduces time
for some exim process initialisations. It does mean that the logging
of TLS configuration problems is only done for the daemon startup.
JH/02 Early-pipelining support code is now included unless disabled in Makefile.
JH/03 DKIM verification defaults no long accept sha1 hashes, to conform to
RFC 8301. They can still be enabled, using the dkim_verify_hashes main
option.
JH/04 Support CHUNKING from an smtp transport using a transport_filter, when
DKIM signing is being done. Previously a transport_filter would always
disable CHUNKING, falling back to traditional DATA.
JH/05 Regard command-line receipients as tainted.
JH/06 Bug 340: Remove the daemon pid file on exit, whe due to SIGTERM.
JH/07 Bug 2489: Fix crash in the "pam" expansion condition. It seems that the
PAM library frees one of the arguments given to it, despite the
documentation. Therefore a plain malloc must be used.
JH/08 Bug 2491: Use tainted buffers for the transport smtp context. Previously
on-stack buffers were used, resulting in a taint trap when DSN information
copied from a received message was written into the buffer.
JH/09 Bug 2493: Harden ARC verify against Outlook, whick has been seen to mix
the ordering of its ARC headers. This caused a crash.
JH/10 Bug 2492: Use tainted memory for retry record when needed. Previously when
a new record was being constructed with information from the peer, a trap
was taken.
JH/11 Bug 2494: Unset the default for dmarc_tld_file. Previously a naiive
installation would get error messages from DMARC verify, when it hit the
nonexistent file indicated by the default. Distros wanting DMARC enabled
should both provide the file and set the option.
Also enforce no DMARC verification for command-line sourced messages.
JH/12 Fix an uninitialised flag in early-pipelining. Previously connections
could, depending on the platform, hang at the STARTTLS response.
JH/13 Bug 2498: Reset a counter used for ARC verify before handling another
message on a connection. Previously if one message had ARC headers and
the following one did not, a crash could result when adding an
Authentication-Results: header.
JH/14 Bug 2500: Rewind some of the common-coding in string handling between the
Exim main code and Exim-related utities. The introduction of taint
tracking also did many adjustments to string handling. Since then, eximon
frequently terminated with an assert failure.
JH/15 When PIPELINING, synch after every hundred or so RCPT commands sent and
check for 452 responses. This slightly helps the inefficieny of doing
a large alias-expansion into a recipient-limited target. The max_rcpt
transport option still applies (and at the current default, will override
the new feature). The check is done for either cause of synch, and forces
a fast-retry of all 452'd recipients using a new MAIL FROM on the same
connection. The new facility is not tunable at this time.
JH/16 Fix the variables set by the gsasl authenticator. Previously a pointer to
library live data was being used, so the results became garbage. Make
copies while it is still usable.
JH/17 Logging: when the deliver_time selector ise set, include the DT= field
on delivery deferred (==) and failed (**) lines (if a delivery was
attemtped). Previously it was only on completion (=>) lines.
JH/18 Authentication: the gsasl driver not provides the $authN variables in time
for the expansion of the server_scram_iter and server_scram_salt options.
WB/01 SPF: DNS lookups for the obsolete SPF RR type done by the libspf2 library
are now specifically given a NO_DATA response without hitting the system
resolver. The library goes on to do the now-standard TXT lookup.
Use of dnsdb lookups is not affected.
JH/19 Bug 2507: Modules: on handling a dynamic-module (lookups) open failure,
only retrieve the errormessage once. Previously two calls to dlerror()
were used, and the second one (for mainlog/paniclog) retrieved null
information.
JH/20 Taint checking: disallow use of tainted data for
- the appendfile transport file and directory options
- the pipe transport command
- the autoreply transport file, log and once options
- file names used by the redirect router (including filter files)
- named-queue names
- paths used by single-key lookups
Previously this was permitted.
JH/21 Bug 2501: Fix init call in the heimdal authenticator. Previously it
adjusted the size of a major service buffer; this failed because the
buffer was in use at the time. Change to a compile-time increase in the
buffer size, when this authenticator is compiled into exim.
JH/22 Taint-checking: move to safe-mode taint checking on all platforms. The
previous fast-mode was untenable in the face of glibs using mmap to
support larger malloc requests.
PP/01 Update the openssl_options possible values through OpenSSL 1.1.1c.
New values supported, if defined on system where compiled:
allow_no_dhe_kex, cryptopro_tlsext_bug, enable_middlebox_compat,
no_anti_replay, no_encrypt_then_mac, prioritize_chacha, tlsext_padding
JH/23 Performance improvement in the initial phase of a two-pass queue run. By
running a limited number of proceses in parallel, a benefit is gained. The
amount varies with the platform hardware and load. The use of the option
queue_run_in_order means we cannot do this, as ordering becomes
indeterminate.
JH/24 Bug 2524: fix the cyrus_sasl auth driver gssapi usage. A previous fix
had introduced a string-copy (for ensuring NUL-termination) which was not
appropriate for that case, which can include embedded NUL bytes in the
block of data. Investigation showed the copy to actually be needless, the
data being length-specified.
JH/25 Fix use of concurrent TLS connections under GnuTLS. When a callout was
done during a receiving connection, and both used TLS, global info was
used rather than per-connection info for tracking the state of data
queued for transmission. This could result in a connection hang.
JH/26 Fix use of the SIZE parameter on MAIL commands, on continued connections.
Previously, when delivering serveral messages down a single connection
only the first would provide a SIZE. This was due to the size information
not being properly tracked.
JH/27 Bug 2530: When operating in a timezone with sub-minute offset, such as
TAI (at 37 seconds currently), pretend to be in UTC for time-related
expansion and logging. Previously, spurious values such as a future
minute could be seen.
JH/28 Bug 2533: Fix expansion of ${tr } item. When called in some situations
it could crash from a null-deref. This could also affect the
${addresses: } operator and ${readsock } item.
JH/29 Bug 2537: Fix $mime_part_count. When a single connection had a non-mime
message following a mime one, the variable was not reset.
JH/30 When an pipelined-connect fails at the first response, assume incorrect
cached capability (perhaps the peer reneged?) and immediately retry in
non-pipelined mode.
JH/31 Fix spurious detection of timeout while writing to transport filter.
JH/32 Bug 2541: Fix segfault on bad cmdline -f (sender) argument. Previously
an attempt to copy the string was made before checking it.
JH/33 Fix the dsearch lookup to return an untainted result. Previously the
taint of the lookup key was maintained; we now regard the presence in the
filesystem as sufficient validation.
JH/34 Fix the readsocket expansion to not segfault when an empty "options"
argument is supplied.
JH/35 The dsearch lookup now requires that the directory is an absolute path.
Previously this was not checked, and nonempty relative paths made an
access under Exim's current working directory.
JH/36 Bug 2554: Fix msg:defer event for the hosts_max_try_hardlimit case.
Previously no event was raised.
JH/37 Bug 2552: Fix the check on spool space during reception to use the SIZE
parameter supplied by the sender MAIL FROM command. Previously it was
ignored, and only the check_spool_space option value for the required
leeway checked.
JH/38 Fix $dkim_key_length. This should, after a DKIM verification, present
the size of the signing public-key. Previously it was instead giving
the size of the signature hash.
JH/39 DKIM verification: the RFC 8301 restriction on sizes of RSA keys is now
the default. See the (new) dkim_verify_min_keysizes option.
JH/40 Fix a memory-handling bug: when a connection carried multiple messages
and an ACL use a lookup for checking either the local_part or domain,
stale data could be accessed. Ensure that variable references are
dropped between messages.
JH/41 Bug 2571: Fix SPA authenticator. Running as a server, an offset supplied
by the client was not checked as pointing within response data before
being used. A malicious client could thus cause an out-of-bounds read and
possibly gain authentication. Fix by adding the check.
JH/42 Internationalisation: change the default for downconversion in the smtp
transport to be "if needed". Previously it was "as previously set" for
the message, which usually meant "if needed" for message-submission but
"no" for everything else. However, MTAs have been seen using SMTPUTF8
even when the envelope addresses did not need it, resulting in forwarding
failures to non-supporting MTAs. A downconvert in such cases will be
a no-op on the addresses, merely dropping the use of SMTPUTF8 by the
transport. The change does mean that addresses needing conversion will
be converted when previously a delivery failure would occur.
JH/43 Fix possible long line in DSN. Previously when a very long SMTP error
response was received it would be used unchecked in a fail-DSN, violating
standards on line-length limits. Truncate if needed.
HS/01 Remove parameters of the link to www.open-spf.org. The linked form
doesn't work. (Additionally add a new main config option to configure the
spf_smtp_comment)

20.1
====
Process
-------
- Document that pip 21.0 will drop support for Python 2.7.
Features
--------
- Add ``pip cache dir`` to show the cache directory.

- Correctly set permissions on metadata files during wheel installation,
to permit non-privileged users to read from system site-packages.
20.1b1
======
Deprecations and Removals
-------------------------
- Remove emails from AUTHORS.txt to prevent usage for spamming, and only populate names in AUTHORS.txt at time of release
- Remove deprecated ``--skip-requirements-regex`` option.
- Building of local directories is now done in place, instead of a temporary
location containing a copy of the directory tree.
- Remove unused ``tests/scripts/test_all_pip.py`` test script and the ``tests/scripts`` folder.
Features
--------
- pip now implements PEP 610, so ``pip freeze`` has better fidelity
in presence of distributions installed from Direct URL requirements.
- Add ``pip cache`` command for inspecting/managing pip's wheel cache.
- Raise error if ``--user`` and ``--target`` are used together in ``pip install``
- Significantly improve performance when ``--find-links`` points to a very large HTML page.
- Indicate when wheel building is skipped, due to lack of the ``wheel`` package.
- Change default behaviour to always cache responses from trusted-host source.
- An alpha version of a new resolver is available via ``--unstable-feature=resolver``.
Bug Fixes
---------
- Correctly freeze a VCS editable package when it is nested inside another VCS repository.

into ``/``.
- Reject VCS URLs with an empty revision.
- Warn when an invalid URL is passed with ``--index-url``
- Use better mechanism for handling temporary files, when recording metadata
about installed files (RECORD) and the installer (INSTALLER).

20.0.2
======
Bug Fixes
---------

Vendored Libraries
------------------
- Upgrade packaging to 20.1
20.0.1
======
Bug Fixes
---------
- Rename an internal module, to avoid ImportErrors due to improper uninstallation.
20.0
====
Process
-------
- Switch to a dedicated CLI tool for vendoring dependencies.
Deprecations and Removals
-------------------------
- Remove wheel tag calculation from pip and use ``packaging.tags``. This
should provide more tags ordered better than in prior releases.
- Deprecate setup.py-based builds that do not generate an ``.egg-info`` directory.
- The pip>=20 wheel cache is not retro-compatible with previous versions. Until
pip 21.0, pip will continue to take advantage of existing legacy cache
entries.
- Deprecate undocumented ``--skip-requirements-regex`` option.
- Deprecate passing install-location-related options via ``--install-option``.
- Use literal "abi3" for wheel tag on CPython 3.x, to align with PEP 384
which only defines it for this platform.
- Remove interpreter-specific major version tag e.g. ``cp3-none-any``
from consideration. This behavior was not documented strictly, and this
tag in particular is `not useful <https://snarky.ca/the-challenges-in-designing-a-library-for-pep-425/>`_.
Anyone with a use case can create an issue with pypa/packaging.
- Wheel processing no longer permits wheels containing more than one top-level
.dist-info directory.
- Support for the ``git+git@`` form of VCS requirement is being deprecated and
will be removed in pip 21.0. Switch to ``git+https://`` or
``git+ssh://``. ``git+git://`` also works but its use is discouraged as it is
insecure.
Features
--------
- Default to doing a user install (as if ``--user`` was passed) when the main
site-packages directory is not writeable and user site-packages are enabled.
- Warn if a path in PATH starts with tilde during ``pip install``.
- Cache wheels built from Git requirements that are considered immutable,
because they point to a commit hash.
- Add option ``--no-python-version-warning`` to silence warnings
related to deprecation of Python versions.
- Cache wheels that ``pip wheel`` built locally, matching what
``pip install`` does. This particularly helps performance in workflows where
``pip wheel`` is used for `building before installing
<https://pip.pypa.io/en/stable/user_guide/#installing-from-local-packages>`_.
Users desiring the original behavior can use ``pip wheel --no-cache-dir``.
- Display CA information in ``pip debug``.
- Show only the filename (instead of full URL), when downloading from PyPI.
- Suggest a more robust command to upgrade pip itself to avoid confusion when the
current pip command is not available as ``pip``.
- Define all old pip console script entrypoints to prevent import issues in
stale wrapper scripts.
- The build step of ``pip wheel`` now builds all wheels to a cache first,
then copies them to the wheel directory all at once.
Before, it built them to a temporary directory and moved
them to the wheel directory one by one.
- Expand ``~`` prefix to user directory in path options, configs, and
environment variables. Values that may be either URL or path are not
currently supported, to avoid ambiguity:
* ``--find-links``
* ``--constraint``, ``-c``
* ``--requirement``, ``-r``
* ``--editable``, ``-e``
Bug Fixes
---------
- Correctly handle system site-packages, in virtual environments created with venv (PEP 405).
- Fix case sensitive comparison of pip freeze when used with -r option.
- Enforce PEP 508 requirement format in ``pyproject.toml``
``build-system.requires``.
- Make ``ensure_dir()`` also ignore ``ENOTEMPTY`` as seen on Windows.
- Fix building packages which specify ``backend-path`` in pyproject.toml.
- Do not attempt to run ``setup.py clean`` after a ``pep517`` build error,
since a ``setup.py`` may not exist in that case.
- Fix passwords being visible in the index-url in
"Downloading <url>" message.
- Change method from shutil.remove to shutil.rmtree in noxfile.py.
- Skip running tests which require subversion, when svn isn't installed
- Fix not sending client certificates when using ``--trusted-host``.
- Make sure ``pip wheel`` never outputs pure python wheels with a
python implementation tag.
- Include ``subdirectory`` URL fragments in cache keys.
- Fix typo in warning message when any of ``--build-option``, ``--global-option``
and ``--install-option`` is used in requirements.txt
- Fix the logging of cached HTTP response shown as downloading.
- Effectively disable the wheel cache when it is not writable, as is the
case with the http cache.
- Correctly handle relative cache directory provided via --cache-dir.

- Document that "coding: utf-8" is supported in requirements.txt
- Explain how to get pip's source code in `Getting Started <https://pip.pypa.io/en/stable/development/getting-started/>`_
- Describe how basic authentication credentials in URLs work.
- Add more clear installation instructions
- Fix documentation links for index options
- Better document the requirements file format
Remove local function pr_open and use it from libmaa library.
So, now paexec requires libmaa.
"mkcmake help" shows configuring variables and descriptions for
targets.
Use mkc's feature "getdelim" instead of local implementation.
So, we need at least mk-configure 0.33.0
Optimization flags defaults to "-O2 -g"
v1.2.0:
* Add ColumnarConverter class
* Add command-line interface utility for document API
* Fix a stable public API for XSD types, elements and attributes
* Add security modes for accessing URLs
2020-05-31 Martin Mares <mj@ucw.cz>
* Released as 3.7.0.
* Added or improved the following capabilities: Designated
Vendor-Specific, Compute eXpress Link, Resizable BARs,
VF Resizable BARs, Link Capabilities 2, Link Status 2.
* On Linux, lspci can show IOMMU groups.
* setpci can be asked to skip bus scan and operate on a device
completely specified by its domain/bus/dev/func address. This
involved major internal cleanup.
* The above feature of setpci uses the pci_get_dev() function,
which obtains a struct pci_dev without doing a bus scan. This was
always possible, but apparently little used, because back-ends
frequently choked when operating on such devices. Fixed a lot
of minor bugs related to this.
* Also, back-ends which do not support domains now correctly fail when
trying to access devices outside domain 0.
* Semantics of pci_fill_info() and pci_dev->known_fields was
underspecified, which lead to inconsistencies between back-ends.
Improved documentation to give a more precise definition and updated
all back-ends to conform to it. Most importantly,
pci_dev->known_fields shows all fields requested over the lifetime
of the pci_dev, but never those which are not supported by the
back-end.
* As usually, updated pci.ids to the current snapshot of the database.
lxqt-panel-0.15.1 / 2020-05-20
==============================
* Bumped version to 0.15.1.
* Fixed a problem in keyboard indicator flag, that might cause a huge amount of error messages.

* Made quicklaunch respect Panel's lock state.
* Added hints for Ctrl+DND to Quick Launch.
* Cleanup and fixes for the taksbar code.
* Release mouse after task button DND (to prevent them from remaining pressed after being dragged).
* Reset panel style sheet before updating it (to update plugin handles with Qt 5.13 when panel orientation changes).
* Removed press-and-hold popup menu from launchers in Quick Launch.
* Check if panel is under mouse on auto-hiding.
* Removed QDesktopWidget from panel.
* Put panel only at an edge of virtual screen (to prevent it from being positioned at the middle of virtual screen).
* Set the geometry of panel before showing it (because, otherwise. some WMs might not position the panel correctly).
* Removed deprecated QImage method `byteCount()` and used `sizeInBytes()` instead.
* Remove deprecated `trUtf8()` and used `tr()` instead.

* Set cursor style in GTK2, GTK3 and xsettingsd.
* Don't use automatic string conversions.
* C++11 code updates.
* A better method to drag and drop monitors in lxqt-config-monitor.
* Removed old mouse accel/sensitivity options.
* Fixed warnings on applying settings in lxqt-config-monitor.
* Fixed forgetting of lxqt-config-monitor's config.
