         * 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 Its configuration parameter is obsolete.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 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.
         * 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

         * NHibernate Linq internals have undergone some minor changes which may breaks 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

         * 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.

         * Sessions concrete classes constructors have been changed. (It is not expected for them to be used

         * 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

         * 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 fetch with TimeSpan instead of
           DateTime.
+        * ODBC: String parameter length will no more be specified by the OdbcDriver.
