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).
** Bug
* #1606 NHibernate 5 precision maximum on decimal reduced vs. NHibernate 4

http://nhibernate.info/doc/nhibernate-reference/index.html
** 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.

=============================
Release notes - NHibernate - Version 4.1.2.GA
** Bug
* #1355 NH-3928 - Random invalid SQL generated when using bitwise operators
Build 4.1.1.GA
=============================
##### Notes #####
The [NH-3904] has been reverted in favor of [NH-2401]: users now required to explicitly specify
custom user type via MappedAs method if they want to use IUserType/ICompositeUserType type
parameters in Linq queries, or implement generators the way they take the types into account.
** Sub-task
* [NH-3940] - Revert NH-3904
** Bug
* [NH-3929] - ExpressionParameterVisitor selects wrong CustomType for ConstantExpression (Linq)
* [NH-3941] - MappedAs() does not work
Build 4.1.0.GA
=============================
##### Possible Breaking Changes Since 4.0 #####
Proxies for classes that used lazy fields (not collections)
would have any exceptions from the entity wrapped in TargetInvocationException. This
wrapping exception have now been removed. Where relevant, you should instead catch
the original exception type you throw.
For LINQ queries, the startAt parameter and the return value for string.IndexOf() are
now correctly translated from .Net's 0-based indexing to SQL's 1-based indexing. LINQ
queries that are written to expect SQL semantics for IndexOf() will likely need to be
adjusted (NH-3846, NH-3901).
Example: A LINQ query should now use 'x=>x.Name.IndexOf("a") == -1' to pick objects where
the name doesn't contain the letter "a".
** Bug
* [NH-3885] - ThreadSafeDictionary is not threadsafe
Build 4.1.0.CR1

Build 4.0.0.GA
=============================
** Known BREAKING CHANGES from NH3.3.3.GA to 4.0.0.GA
NHibernate now targets .Net 4.0. Many uses of set types from Iesi.Collections have
now been changed to use corresponding types from the BCL. The API for these types
are slightly different.
Support for persistent non-generic collections removed. Use the generic counterparts instead.
##### Possible Breaking Changes #####
* IDeleteEventListener, IEventSource: Use generic ISet<> instead of non-generic in method signatures.
* SqlString.Parts removed. Use SqlString.Count and SqlString.GetEnumerator().
* IPersistentCollection.GetSnapshot() now returns object instead of ICollection. The snapshot should be opaque to outside code.
* Removed IsDiscriminatorFormula, DiscriminatorFormula and GenerateSelectString from UnionSubclassEntityPersister class.
* Removed ManagedWebSessionContext. Any configuration files which use the "managed_web" session context should now use "web"
* SybaseASADialect removed: Use SybaseSQLAnywhere10Dialect instead.
* ASA10ClientDriver, ASAClientDriver and SQLiteDriver removed: Use SybaseSQLAnywhereDriver, SybaseAsaClientDriver, SQLite20Driver instead.
* Removed Classic HQL Parser.
* Removed IQueryTranslatorFactory2. It's methods were pulled up to IQueryTranslatorFactory. Method CreateQueryTranslators accepting string as first argument marked as Obsolete.
* IQueryExpression.Translate now has second boolean argument 'filter'
* Added several methods which accepts IQueryExpression to ISessionImplementor, which is duplicating methods which accepts string.
* Miss-spelled AdoNetWithDistrubtedTransactionFactory removed: Use AdoNetWithDistributedTransactionFactory instead
* HqlDistinctHolder removed: Use HqlExpressionSubTreeHolder instead
* DisableLogFormattedSql method removed: the default is disabled
* ISession.SaveOrUpdateCopy removed: Use Merge instead
* Oracle and MySQL: The atan2 and power functions now return double (instead of single) for consistency with other dialects.
* Removed FirebirdDriver. It was the same as FirebirdClientDriver since 3.2, and the latter have been the default since then.
* Removed bunch of unused methods on *Helper classes
* Static fields on NHibernateUtil are declared as their exact class
From NH4.0.0.Alpha1 to 4.0.0.Alpha2:
Fixed mapping by code behaviour when map child subclasses (see NH-3135 and NH-3269)
The constructor of AbstractComponentTuplizer now behaves like AbstractEntityTuplizer in the way
that it doesn't create the instantiator any more. Custom component tuplizers that derive
directly from AbstractComponentTuplizer need to add this line of code in their constructor:
instantiator = BuildInstantiator(component);
From NH4.0.0.Alpha2 to 4.0.0.CR1:
The interface IEnhancedProjection was removed and its methods moved to IProjection.
Two other overloads of the GetColumnAliases() methods was removed from IProjection.
* [NH-2290] Invalid hql parenthesis expansion in generated sql
Unary minus before parentheses in HQL lost the parentheses when translated
to SQL and therefore the wrong value was returned. This use of unary minus is now
implemented in the mathematically correct way.
