** Task
* #2200 Release 5.2.6
* #2199 Upgrade AsyncGenerator to 0.8.2.12
** Tests

Build 5.2.5
=============================
Release notes - NHibernate - Version 5.2.5
5 issues were resolved in this release.
** Bug
* #2075 Missing cast when comparing a guid and string columns in SAP SQL Anywhere
* #2046 Fix nullable Guid ToString is not translated correctly on some dialects
* #2043 System.Reflection.TargetException when an interface is used as class mapping proxy definition
* #2040 Incorrect SQL when comparing a guid and string column in Sql Server
** Task
* #2086 Release 5.2.5
Build 5.2.4
=============================
Release notes - NHibernate - Version 5.2.4
3 issues were resolved in this release. The dialect change has the side effect of
re-enabling a hack used by NHibernate.Spatial, allowing Spatial users to upgrade
to NHibernate 5.2.x. See NHibernate.Spatial#104.
##### Possible Breaking Changes #####
* Using DML on an entity collection was applying the changes without
filtering according to the entity. It will now throw a
NotSupportedException.
** Bug
* #2020 Throw for DML on filter
* #2011 Use a statically resolved dialect when building the session factory
** Task
* #2030 Release 5.2.4
As part of releasing 5.2.4, a missing 5.2.0 possible breaking change has been added about
property-ref on null values. See 5.2.0 possible breaking changes.
Build 5.2.3
=============================
Release notes - NHibernate - Version 5.2.3
1 issue was resolved in this release.
** Bug
* #1964 Unable to serialize session because SerializationFieldInfo is not marked as serializable
Build 5.2.2
=============================
Release notes - NHibernate - Version 5.2.2
3 issues were resolved in this release.
** Bug
* #1953 Query space invalidation doesn't work for bulk actions
* #1269 NH-3069 - Cannot use Session.Lock with Version column on abstract base class
** Task
* #1957 Release 5.2.2
Build 5.2.1
=============================
Release notes - NHibernate - Version 5.2.1
5 issues were resolved in this release.
** Bug
* #1928 JoinAlias on JoinQueryOver fails
* #1920 ISession.Get may fail with a null exception
* #1918 Property-ref on many-to-one with composite id fails
** Task
* #1932 Release 5.2.1
* #1927 Add missing possible breaking change
As part of releasing 5.2.1, a missing 5.2.0 possible breaking change has been added about duplicated columns
in mapping. See 5.2.0 possible breaking changes.
Build 5.2.0
=============================
Release notes - NHibernate - Version 5.2.0
157 issues were resolved in this release.
##### Possible Breaking Changes #####
* Entities having many non-readonly properties (including many-to-one) mapped to
the same column will no more silently ignore the trouble till an insert or update
is attempted. They will now cause the session factory built to fail. When
mapping many properties to the same column, all of them excepted at most one
should be mapped with `insert="false" update="false"`.
* Mappings mixing column elements and formula elements were taking into account
only the formula elements. They will now take into account all elements.
* Mappings mixing column elements and/or formula elements with a column attribute
or a formula attribute were silently ignoring the attribute. They will now throw.
* Mappings mixing a column attribute and a formula attribute were silently doing
some best effort logic, either considering this as a two columns mapping, the
second one being the formula (most cases), or only taking into account the
formula (case of the `<element>` mapping). They will now throw.
* NHibernate StringType has gained case-sensitivity and culture parameters.
Previously it was ignoring parameters. This type may change its behavior
for any mapping having defined parameters for this type. See #1833.
* Mapping a dynamic component with a Hashtable property instead of an
IDictionary is no more supported.
* Querying a dynamic entity as a Hashtable instead of an IDictionary is no more
supported.
* A collection mapped with a `property-ref` will no more support being accessed
when the referenced property is null. It will throw. Previously, the collection
was not throwing but was always loaded empty.
* With PostgreSQL, a HQL query using the bitwise xor operator "^" or "bxor"
was exponentiating the arguments instead. It will now correctly apply the xor
operator. (# operator in PostgreSQL SQL.)
* Auto-generated constraint names will not be the same than the ones generated
with previous NHibernate versions under .Net Framework. (Under .Net Core those
names were anyway changing at each run.) The new ones will be the same
whatever the runtime used for generating them.
* Some generated PK names may change, if a table name has a quoting symbol at
precise 13th character.
* The WcfOperationSessionContext has been removed from .Net Core and .Net
Standard builds. See #1842.
* Some classes, which were not serializing the session factory, do now serialize it.
In case of cross-process serialization/deserialization, these session factories
will need to be properly named, by setting the session_factory_name setting in the
configuration used to build them. This may mainly affect users of a distributed
second level cache, if their cache implementation uses binary serialization.
Affected classes are: CacheKey, CollectionKey, EntityKey and EntityUniqueKey.
* Some types cache representations have changed. Out-of-process second level
caches should be cleared after upgrading NHibernate, if some of those types
were cached. The concerned types are: CultureInfoType, TypeType, UriType,
XDocType, XmlDocType.
* Dialect.GetIdentitySelectString was called by the entity persisters with
inverted parameter values: the table name in the column parameter, and the
column name in the table parameter. No built-in dialects were using the
parameter values. External dialects which were using it inverted (causing issues
to collection persisters, which have always supplied them correctly) needs
to be accordingly adjusted.
* Users providing through an IObjectFactory some custom logic for instantiating
value types will now need to supply their own result transformer if they were
using AliasToBeanResultTransformer with value types, or their own entity
tuplizer if they were using value types as entities.
* Users providing through an IObjectFactory some custom logic for instantiating
their custom session contexts will have to implement
ICurrentSessionContextWithFactory and add a parameterless public constructor
to their custom context, and move their custom instantiation logic from
IObjectsFactory.CreateInstance(Type, object[]) to
IObjectsFactory.CreateInstance(Type).
* Various *Binding classes of NHibernate will now always have their protected
dialect field null. (These classes are not expected to be derived by users,
as there is no way to use custom descendants with NHibernate.)
* AbstractPersistentCollection.AfterInitialize does no more perform queued
operations. Queued operations are now run by a later call to a new method,
ApplyPendingOperations. Concrete custom implementations relying on the queued
operations to be done by their base AfterInitialize will need to be changed
accordingly.
** Bug

Build 5.1.0
=============================
Release notes - NHibernate - Version 5.1.0
** Highlights
* NHibernate has gained two new target frameworks: .Net Core 2.0 and .Net Standard 2.0. NHibernate NuGet package
provides them, along with the .Net framework 4.6.1 build.
For these new frameworks, some additional specificities or limitations apply:
* Binary serialization is not supported - the user shall implement serialization surrogates for System.Type,
FieldInfo, PropertyInfo, MethodInfo, ConstructorInfo, Delegate, etc.
* SqlClient, Odbc, Oledb drivers are converted to ReflectionBasedDriver to avoid the extra dependencies.
* CallSessionContext uses a static AsyncLocal field to mimic the CallContext behavior.
* System transactions (transaction scopes) are untested, due to the lack of data providers supporting them.
* 114 issues were resolved in this release.
##### Possible Breaking Changes #####
* Since Ingres9Dialect is now supporting sequences, the enhanced-sequence identifier generator will default to
using a sequence instead of a table. Revert to previous behavior by using its force_table_use parameter.
* Some overridable methods of the Dialect base class and of MsSql2000Dialect have been obsoleted in favor of
new methods. Dialects implementors need to override the replacing methods if they were overriding the
obsolete ones, which are:
* Dialect.GetIfNotExistsCreateConstraint(Table table, string name), replaced by
GetIfNotExistsCreateConstraint(string catalog, string schema, string table, string name).
* Dialect.GetIfNotExistsCreateConstraintEnd(Table table, string name), replaced by
GetIfNotExistsCreateConstraintEnd(string catalog, string schema, string table, string name).
* Dialect.GetIfExistsDropConstraint(Table table, string name), replaced by
GetIfExistsDropConstraint(string catalog, string schema, string table, string name).
* Dialect.GetIfExistsDropConstraintEnd(Table table, string name), replaced by
GetIfExistsDropConstraintEnd(string catalog, string schema, string table, string name).
* MsSql2000Dialect.GetSelectExistingObject(string name, Table table), replaced by
GetSelectExistingObject(string catalog, string schema, string table, string name).

** Known BREAKING CHANGES from NH4.1.1.GA to 5.0.0
NHibernate now targets .Net 4.6.1.
Remotion.Linq and Antlr3 libraries are no more merged in the NHibernate library,
and must be deployed along NHibernate library. (NuGet will reference them.)
Classes and members which were flagged as obsolete in the NHibernate 4.x series have been dropped.
Prior to upgrading, fix any obsolete warning according to its message. See NH-4075 and NH-3684 for a list.
##### Possible Breaking Changes #####
* All members exposing some System.Data types have been changed for the corresponding System.Data.Common
types. (IDbCommand => DbCommand, ...)
* The Date NHibernate type will no more replace by null values below its base value (which was year 1753).
Its base value is now DateTime.MinValue. Its configuration parameter is obsolete.
* NHibernate type DateTimeType, which is the default for a .Net DateTime, does no longer cut fractional
seconds. Use DateTimeNoMsType if you wish to have fractional seconds cut. It applies to its Local/Utc
counterparts too.
* LocalDateTimeType and UtcDateTimeType do no more accept being set with a value having a non-matching kind,
they throw instead.
* DbTimestamp will now round the retrieved value according to Dialect.TimestampResolutionInTicks.
* When an object typed property is mapped to a NHibernate timestamp, setting an invalid object in the
property will now throw at flush instead of replacing it with DateTime.Now.
* Decimal type registration now correctly handles maximal precision. For most dialects, it is 28, matching
the .Net limit. Values in mappings above maximal precision will be reduced to maximal precision.
* Default cast types do no more resolve string to 255 length and decimal to its default precision/scale for
the dialect. They resolve to 4000 length string and (28, 10) precision/scale decimals by default, and are
trimmed down according to dialect. Those defaults can be overridden with query.default_cast_length,
query.default_cast_precision and query.default_cast_scale settings.
* Future queries with data provider not actually supporting them (not supporting mutliple queries in a single
SQL command) are no more immediately executed at the .Future call. They are executed only when directly
enumerated or when their IFutureEnumerable.GetEnumerable method is called. (This aligns them with the behavior
of FutureValue.)
* Dialects are now configurable. If you instantiate a dialect directly, make sure you call its Configure
method, with as argument the properties of a NHibernate Configuration object. You may use instead
Dialect.GetDialect methods, which configure the dialect before returning it.
* Transaction scopes handling has undergone a major rework. See NH-4011 for full details.
** More transaction promotion to distributed may occur if you use the "flush on commit" feature with
transaction scopes. Explicitly flush your session instead. Ensure it does not occur by disabling
transaction.use_connection_on_system_prepare setting.
** After transaction events no more allow using the connection when they are raised from a scope
completion.
** Connection enlistment in an ambient transaction is now enforced by NHibernate by default.
** The connection releasing is no more directly triggered by a scope completion, but by later
interactions with the session.
* AdoNetWithDistributedTransactionFactory has been renamed AdoNetWithSystemTransactionFactory.
* Subcriteria.UniqueResult<T> for value types now return default(T) when result is null, as was
already doing CriteriaImpl.UniqueResult<T>.
* AliasToBeanResultTransformer property/field resolution logic has changed for supporting members
which names differ only by case. See NH-3693 last comments for details.
* Linq inequality implementation has been changed for supporting null, meaning that a "a != b" expression
will now be considered matching if one side is null, while previously due to SQL null semantic it was
considered non-matching. See NH-3100.
* Linq extension methods marked with attribute LinqExtensionMethod will no more be evaluated
in-memory prior to query execution when they do not depend on query results, but will always be
translated to their corresponding SQL call. This can be changed with a parameter of the attribute.
* Linq Query methods are now native members of ISession and IStatelessSession instead of being
extension methods.
* Linq provider now use Remotion.Linq v2, which may break Linq provider extensions, mainly due to names
changes. See https://github.com/nhibernate/nhibernate-core/pull/568 changes to test files for examples.
* NHibernate Linq internals have undergone some minor changes which may break custom Linq providers due
to method signature changes and additional methods to implement.
* IMapping interface has an additional Dialect member. ISessionFactoryImplementor has lost it, since it
gains it back through IMapping.
* IDriver.ExpandQueryParameters and DriverBase.CloneParameter take an additional argument.
* NullableType, its descendent (notably all PrimitiveType) and IUserType value getters and setters now
take the session as an argument. This should mainly impact custom types implementors.
* EmitUtil is now internal and has been cleaned of unused members.
* ContraintOrderedTableKeyColumnClosure has been renamed ConstraintOrderedTableKeyColumnClosure.
* enabledFilter parameter has been removed from IProjection.ToSqlString and ICriterion.ToSqlString methods.
* Proxy factory and proxy cache now use TypeInfo instead of System.Type. This should be transparent for
most users.
* Exceptions which were based on ApplicationException are now based on Exception: HibernateException,
ParserException and AssertionFailure. The logger factory which could throw a bare ApplicationException
now throws an InstantiationException instead.
* ThreadSafeDictionary class has been removed. Use System.Collections.Concurrent.ConcurrentDictionary
instead.
* Entity mode switching capability, which had never been fully implemented, is dropped.
* BytecodeProviderImpl, intended for .Net Framework 1 and broken, is dropped.
* Sessions concrete classes constructors have been changed. (It is not expected for them to be used
directly.)
* Obsolete setting interceptors.beforetransactioncompletion_ignore_exceptions is dropped.
* SQL Server 2008+ dialects now use datetime2 instead of datetime for all date-time types, including
timestamp. This can be reverted with sql_types.keep_datetime setting.
* SQL Server 2008+ timestamp resolution is now 100ns in accordance with datetime2 capabilities, down from
10ms previously. This can be reverted with sql_types.keep_datetime setting.
* Oracle 9g+ dialects now use timestamp(7) for all date time types, instead of timestamp(4).
* Oracle 9g+ timestamp resolution is now 100ns in accordance with timestamp(7) capabilities, down from
100µs previously.
* Oracle: Hbm2dll will no-more choose N- prefixed types for typing Unicode string columns by default.
This can be changed with oracle.use_n_prefixed_types_for_unicode setting, which will furthermore
control DbCommand parameters typing accordingly. See NH-4062.
* SqlServerCe: the id generator "native" will now resolve as table-hilo instead of identity.
* Firebird: timestamp resolution is now 1ms.
* PostgreSQL: if Npgsql v3 or later is used, time DbParameters will be fetched as TimeSpan instead of
DateTime.
* DB2 & Oracle lite: decimal type registration was hardcoding precision as 19 and was using length as
scale. It now uses precision and scale from mapping when specified, and disregards length.
* Ingres & Sybase ASA: decimal type registration was hardcoding precision as 18 and was using length as
scale. It now uses precision and scale from mapping when specified, and disregards length.
* ODBC: String parameter length will no more be specified by the OdbcDriver.
