0.13.8 - 2018-09-24
===================
Fixed
-----
- Filesystem errors when trying to set permissions during a masterlist update
that clones a new repository.
0.13.7 - 2018-09-10
===================
Changed
-------
- Significantly improve plugin loading performance by scanning for BSAs/BA2s
once instead of for each plugin.
- Improve performance of metadata evaluation by caching CRCs with the same
cache lifetime as condition results.
- Improve performance of sorting when it involves long plugin interaction
chains.
- Updated esplugin to v2.0.1.
- Updated libgit2 to v0.27.4.
- Updated libloadorder v11.4.1.
- Updated spdlog to v1.1.0.
- Updated yaml-cpp to 0.6.2+merge-key-support.2.
Fixed
-----
- Fallout 4's `DLCUltraHighResolution.esm` is now handled as a hardcoded plugin
(via libloadorder).
0.13.6 - 2018-06-29
===================
Changed
-------
- Tweaked masterlist repository cloning to avoid undefined behaviour.
- Updated Boost to v1.67.0.
- Updated esplugin to v2.0.0.
- Updated libgit2 to v0.27.2.
- Updated libloadorder to v11.4.0.
0.13.5 - 2018-06-02
===================
Changed
-------
- Sorting now enforces hardcoded plugin positions, sourcing them through
libloadorder. This avoids the need for often very verbose metadata entries,
particularly for Creation Club plugins.
- Updated libgit2 to v0.27.1. This includes a security fix for CVE-2018-11235,
but LOOT API's usage is not susceptible. libgit2 is not susceptible to
CVE-2018-11233, another Git vulnerability which was published on the same day.
- Updated libloadorder to v11.3.0.
- Updated spdlog to v0.17.0.
- Updated esplugin to v1.0.10.
0.13.4 - 2018-06-02
===================
Fixed
-----
- :cpp:any:`NewMetadata()` now uses the passed plugin's group if the calling
plugin's group is implicit, and sets the group to be implicit if the two
plugins' groups are equal.
0.13.3 - 2018-05-26
===================
Changed
-------
- Improved cycle avoidance when resolving evaluating plugin groups during
sorting. If enforcing the group difference between two plugins would cause a
cycle and one of the plugins' groups is the default group, that plugin's group
will be ignored for all plugins in groups between default and the other
plugin's group.
- The masterlist repository cloning process no longer moves LOOT's game folders,
so if something goes wrong the process fails more safely.
- The LOOT API is now built with debugging information on Windows, and its PDB
is included in build archives.
- Updated libloadorder to v11.2.2.
Fixed
-----
- Various filesystem-related issues that could be encountered when updating
masterlists, including failure due to file handles being left open while
attempting to remove.
- Building the esplugin and libloadorder dependencies using Rust 1.26.0, which
included a `regression`_ to workspace builds.

0.13.2 - 2018-04-29
===================
Changed
-------
- Updated libloadorder to v11.2.1.
Fixed
-----
- Incorrect load order positions were given for light-master-flagged ``.esp``
plugins when getting the load order (via libloadorder).
0.13.1 - 2018-04-09
===================
Added
-----
- Support for Skyrim VR using ``GameType::tes5vr``.
Changed
-------
- Updated libloadorder to v11.2.0.
0.13.0 - 2018-04-02
===================
Added
-----
- Group metadata as a replacement for priority metadata. Each plugin belongs to
a group, and a group can load after other groups. Plugins belong to the
``default`` group by default.
- Added the :cpp:any:`loot::Group` class to represent a group.
- Added :cpp:any:`loot::UndefinedGroupError`.
- Added :cpp:any:`GetGroups()`, :cpp:any:`GetUserGroups()` and :cpp:any:`SetUserGroups()`.
- Added :cpp:any:`GetGroup()`, :cpp:any:`IsGroupExplicit()`
and :cpp:any:`SetGroup()`.
- Updated :cpp:any:`MergeMetadata()` to replace the existing
group with the given object's group if the latter is explicit.
- Updated :cpp:any:`NewMetadata()` to return an object using
the called object's group.
- Updated :cpp:any:`HasNameOnly()` to check the group is
implicit.
- Updated :cpp:any:`SortPlugins()` to take into account plugin
groups.
Changed
-------
- :cpp:any:`LoadPlugins()` and
:cpp:any:`SortPlugins()` no longer load the current load order
state, so :cpp:any:`LoadCurrentLoadOrderState()` must be called
separately.
- Updated libgit2 to v0.27.0.
- Updated libloadorder to v11.1.0.
Removed
-------
- Support for local and global plugin priorities.
- Removed the ``loot::Priority`` class.
- Removed ``PluginMetadata::GetLocalPriority()``,
``PluginMetadata::GetGlobalPriority()``,
``PluginMetadata::SetLocalPriority()`` and
``PluginMetadata::SetGlobalPriority()``
- Priorities are no longer taken into account when sorting plugins.
Fixed
-----
- An error when applying a load order for Morrowind, Oblivion, Fallout 3 or
Fallout: New Vegas when a plugin had a timestamp earlier than 1970-01-01
00:00:00 UTC (via libloadorder).
- An error when loading the current load order for Skyrim with a
``loadorder.txt`` incorrectly encoded in Windows-1252 (via libloadorder).
0.12.5 - 2018-02-17
===================
Changed
-------
- Updated esplugin to v1.0.9.
- Updated libgit2 to v0.26.3. This enables TLS 1.2 support on Windows 7, so
users shouldn't need to manually enable it themselves.
0.12.4 - 2018-02-17
===================
Fixed
-----
- Loading or saving a load order could be very slow because the plugins
directory was scanned recursively, which is unnecessary. In the reported case,
this fix caused saving a load order to go from 23 seconds to 43 milliseconds
(via libloadorder).
- Plugin parsing errors were being logged with trace severity, they are now
logged as errors.
- Saving a load order for Oblivion, Fallout 3 or Fallout: New Vegas now updates
plugin access times to the current time for correctness (via libloadorder).
Changed
-------
- ``GameInterface::SetLoadOrder()`` now errors if passed a load order that does
not contain all installed plugins. The previous behaviour was to append any
missing plugins, but this was undefined and could cause unexpected results
(via libloadorder).
- Performance improvements for load order operations, benchmarked at 2x to 150x
faster (via libloadorder).
- Updated mentions of libespm in error messages to mention esplugin instead.
- Updated libloadorder to v11.0.1.
- Updated spdlog to v0.16.3.
0.12.3 - 2018-02-04
===================
Added
-----
- Support for Fallout 4 VR via the new :cpp:any:`loot::GameType::fo4vr` game type.
Fixed
-----
- :cpp:any:`loot::CreateGameHandle()` no longer accepts an empty game path
string, and no longer has a default value for its game path parameter, as
using an empty string as the game path is invalid and always causes an
exception to be thrown.
Changed
-------
- Added an empty string as the default value of
:cpp:any:`loot::InitialiseLocale()`'s string parameter.
- Updated esplugin to v1.0.8.
- Updated libloadorder to v10.1.0.
0.12.2 - 2017-12-24
===================
Fixed
-----
- Plugins with a ``.esp`` file extension that have the light master flag set are
no longer treated as masters when sorting, so they can have other ``.esp``
files as masters without causing cyclic interaction sorting errors.
Changed
-------
- Downgraded Boost to 1.63.0 to take advantage of pre-built binaries on AppVeyor.
0.12.1 - 2017-11-23
===================
Added
-----
- Support for identifying Creation Club plugins using ``Skyrim.ccc`` and ``Fallout4.ccc`` (via libloadorder).
Changed
-------
- Update esplugin to v1.0.7.
- Update libloadorder to v10.0.4.
0.12.0 - 2017-11-03
===================
Added
-----
- Support for light master (``.esl``) plugins.
- :cpp:any:`LoadCurrentLoadOrderState()` in :cpp:any:`loot::GameInterface` to
expose load order cache management to clients, as libloadorder no longer
internally manages it.
- :cpp:any:`loot::SetLoggingCallback()` to allow clients to handle the LOOT
API's logging statements themselves.
- Logging of libloadorder error details.
Changed
-------
- :cpp:any:`LoadPlugins()` now loads the current load order
state before loading plugins.
- Added a `condition` string field to :cpp:any:`SimpleMessage`.
- Replaced libespm dependency with esplugin v1.0.6. This significantly improves
safety and sorting performance, especially for large load orders.
- Updated libloadorder to v10.0.3. This significantly improves safety and the
performance of load order operations, at the expense of exposing cache
management to the client.
- Replaced Boost.Log with spdlog v0.14.0, removing dependencies on several other
Boost libraries in the process.
- Updated libgit2 to v0.26.0.
- Update Boost to v1.65.1.
Removed
-------
- ``DatabaseInterface::EvalLists()`` as it was superseded in v0.11.0 by the
ability to evaluate conditions when getting general messages and individual
plugins' metadata, which is more efficient.
- ``SetLoggingVerbosity()`` and ``SetLogFile()`` as they have been superseded
by the new :cpp:any:`loot::SetLoggingCallback()` function.
- The ``loot/yaml/*`` headers containing LOOT's internal YAML conversion
functions are no longer exposed alongside the API headers.
- The ``loot/windows_encoding_converters.h`` header is no longer exposed
alongside the API headers.
Fixed
-----
- Formatting in metadata documentation.
- Saving metadata wrote entries in an inconsistent order.
- Clang build errors.
0.11.1 - 2017-06-19
===================
Fixed
-----
- A crash would occur when loading an plugin that had invalid data past its
header. Such plugins are now just silently ignored.
- :cpp:any:`loot::CreateGameHandle()` would not resolve game or local data paths
that are junction links correctly, which caused problems later when trying to
perform actions such as loading plugins.
- Performing a masterlist update on a branch where the remote and local
histories had diverged would fail. The existing local branch is now discarded
and the remote branch checked out anew, as intended.
0.11.0 - 2017-05-13
===================
Added
-----
- New functions to :cpp:class:`loot::DatabaseInterface`:
- :cpp:any:`WriteUserMetadata()`
- :cpp:any:`GetKnownBashTags()`
- :cpp:any:`GetGeneralMessages()`
- :cpp:any:`GetPluginMetadata()`
- :cpp:any:`GetPluginUserMetadata()`
- :cpp:any:`SetPluginUserMetadata()`
- :cpp:any:`DiscardPluginUserMetadata()`
- :cpp:any:`DiscardAllUserMetadata()`
- :cpp:any:`IsLatestMasterlist()`
- A :cpp:any:`loot::GameInterface` pure abstract class that exposes methods for
accessing game-specific functionality.
- A :cpp:any:`loot::PluginInterface` pure abstract class that exposes methods
for accessing plugin file data.
- The :cpp:any:`loot::SetLoggingVerbosity()` and :cpp:any:`loot::SetLogFile()`
functions and :cpp:any:`loot::LogVerbosity` enum for controlling the API's
logging behaviour.
- An :cpp:any:`loot::InitialiseLocale()` function that must be called to
configure the API's locale before any of its other functionality is used.
- LOOT's internal metadata classes are now exposed as part of the API.
Changed
-------
- Renamed ``loot::CreateDatabase()`` to :cpp:any:`loot::CreateGameHandle()`, and
changed its signature so that it returns a shared pointer to a
:cpp:any:`loot::GameInterface` instead of a shared pointer to a
:cpp:any:`loot::DatabaseInterface`.
- Moved :cpp:any:`SortPlugins()` into :cpp:any:`loot::GameInterface`.
- Some :cpp:any:`loot::DatabaseInterface` methods are now const:
- :cpp:any:`WriteMinimalList()`
- :cpp:any:`GetMasterlistRevision()`
- LOOT's internal YAML conversion functions have been refactored into the
``include/loot/yaml`` directory, but they are not really part of the API.
They're only exposed so that they can be shared between the API and LOOT
application without introducing another component.
- LOOT's internal string encoding conversion functions have been refactored into
the ``include/loot/windows_encoding_converters.h`` header, but are not really
part of the API. They're only exposed so that they can be shared between the
API and LOOT application without introducing another component.
- Metadata is now cached more efficiently, reducing the API's memory footprint.
- Log timestamps now have microsecond precision.
- Updated to libgit2 v0.25.1.
- Refactored code only useful to the LOOT application out of the API internals
and into the application source code.
Removed
-------
- ``DatabaseInterface::GetPluginTags()``,
``DatabaseInterface::GetPluginMessages()`` and
``DatabaseInterface::GetPluginCleanliness()`` have been removed as they have
been superseded by ``DatabaseInterface::GetPluginMetadata()``.
- The ``GameDetectionError`` class, as it is no longer thrown by the API.
- The ``PluginTags`` struct, as it is no longer used.
- The ``LanguageCode`` enum, as the API now uses ISO language codes directly
instead.
- The ``PluginCleanliness`` enum. as it's no longer used. Plugin cleanliness
should now be checked by getting a plugin's evaluated metadata and checking
if any dirty info is present. If none is present, the cleanliness is unknown.
If dirty info is present, check if any of the English info strings contain the
text "Do not clean": if not, the plugin is dirty.
- The LOOT API no longer caches the load order, as this is already done more
accurately by libloadorder (which is used internally).
Fixed
-----
- Libgit2 error details were not being logged.
- A FileAccessError was thrown when the masterlist path was an empty string. The
API now just skips trying to load the masterlist in this case.
- Updating the masterlist did not update the cached metadata, requiring a call
to :cpp:any:`LoadLists()`.
- The reference documentation was broken due to an incompatibility between
Sphinx 1.5.x and Breathe 4.4.
0.10.3 - 2017-01-08
===================
Added
-----
- Automated 64-bit API builds.
Changed
-------
- Replaced ``std::invalid_argument`` exceptions thrown during condition evaluation with ``ConditionSyntaxError`` exceptions.
- Improved robustness of error handling when calculating file CRCs.
Fixed
-----
- Documentation was not generated correctly for enums, exceptions and structs exposed by the API.
- Added missing documentation for ``CyclicInteractionError`` methods.
0.10.2 - 2016-12-03
===================
Changed
-------
- Updated libgit2 to 0.24.3.
Fixed
-----
- A crash could occur if some plugins that are hardcoded to always load were missing. Fixed by updating to libloadorder v9.5.4.
- Plugin cleaning metadata with no ``info`` value generated a warning message with no text.
0.10.1 - 2016-11-12
===================
No API changes.
0.10.0 - 2016-11-06
===================
Added
-----
* Support for TES V: Skyrim Special Edition.
Changed
-------
* Completely rewrote the API as a C++ API. The C API has been reimplemented as
a wrapper around the C++ API, and can be found in a `separate repository`_.
* Windows builds now have a runtime dependency on the MSVC 2015 runtime
redistributable.
* Rewrote the API documentation, which is now hosted online at `Read The Docs`_.
* The Windows release archive includes the ``.lib`` file for compile-time linking.
* LOOT now supports v0.10 of the metadata syntax. This breaks compatibility with existing syntax. See :doc:`the syntax version history <../metadata/changelog>` for the details.
* Updated libgit2 to 0.24.2.
Removed
-------
* The ``loot_get_tag_map()`` function has no equivalent in the new C++ API as it
is obsolete.
* The ``loot_apply_load_order()`` function has no equivalent in the new C++ API
as it just passed through to libloadorder, which clients can use directly
instead.
Fixed
-----
* Database creation was failing when passing paths to symlinks that point to
the game and/or game local paths.
* Cached plugin CRCs causing checksum conditions to always evaluate to false.
* Updating the masterlist when the user's ``TEMP`` and ``TMP`` environmental variables point to a different drive than the one LOOT is installed on.

0.9.2 - 2016-08-03
==================
Changed
-------
* libespm (2.5.5) and Pseudosem (1.1.0) dependencies have been updated to the
versions given in brackets.
Fixed
-----
* The packaging script used to create API archives was packaging the wrong
binary, which caused the v0.9.0 and v0.9.1 API releases to actually be
re-releases of a snapshot build made at some point between v0.8.1 and v0.9.0:
the affected API releases were taken offline once this was discovered.
* ``loot_get_plugin_tags()`` remembering results and including them in the
results of subsequent calls.
* An error occurred when the user's temporary files directory didn't
exist and updating the masterlist tried to create a directory there.
* Errors when reading some Oblivion plugins during sorting, including
the official DLC.
0.9.1 - 2016-06-23
==================
No API changes.
0.9.0 - 2016-05-21
==================
Changed
-------
* Moved API header location to the more standard ``include/loot/api.h``.
* Documented LOOT's masterlist versioning system.
* Made all API outputs fully const to make it clear they should not be
modified and to avoid internal const casting.
* The ``loot_db`` type is now an opaque struct, and functions that used to take
it as a value now take a pointer to it.
Removed
-------
* The ``loot_cleanup()`` function, as the one string it used to destroy
is now stored on the stack and so destroyed when the API is unloaded.
* The ``loot_lang_any`` constant. The ``loot_lang_english`` constant
should be used instead.
0.8.1 - 2015-09-27
==================
Changed
-------
* Safety checks are now performed on file paths when parsing conditions (paths
must not reference a location outside the game folder).
* Updated Boost (1.59.0), libgit2 (0.23.2) and CEF (branch 2454) dependencies.
Fixed
-----
* A crash when loading plugins due to lack of thread safety.
* The masterlist updater and validator not checking for valid condition
and regex syntax.
* The masterlist updater not working correctly on Windows Vista.
0.8.0 - 2015-07-22
==================
Added
-----
* Support for metadata syntax v0.8.
Changed
-------
* Improved plugin loading performance for computers with weaker multithreading
capabilities (eg. non-hyperthreaded dual-core or single-core CPUs).
* LOOT no longer outputs validity warnings for inactive plugins.
* Updated libgit2 to v0.23.0.
Fixed
-----
* Many miscellaneous bugs, including initialisation crashes and
incorrect metadata input/output handling.
* LOOT silently discarding some non-unique metadata: an error will now
occur when loading or attempting to apply such metadata.
* LOOT's version comparison behaviour for a wide variety of version string
formats.
0.7.1 - 2015-06-22
==================
Fixed
-----
* "No existing load order position" errors when sorting.
* Output of Bash Tag removal suggestions in ``loot_write_minimal_list()``.
0.7.0 - 2015-05-20
==================
Initial API release.
