• Need to add on annotated property @SerialName("myProperty") the @MongoProperty annotation: see https://litote.org/kmongo/object-mapping/#workaround-around-typed-queries-and-serialname

• #213 Unnecessary suspend modifier for 'CoroutineCollection.aggregate'

• #198 commitTransactionAndAwait() -> No value received via onNext for awaitSingle
• #200 getting compilation error on version 4.0.0 (doc update)

This version is using the 4.0 java driver version and is a breaking changes release. Please consult http://litote.org/kmongo/about/#upgrading-to-4x-from-312x before upgrading.

Also in this release:

• #190 Nullable args in documentation
• #191 .json not translating Pattern correctly

• #182 Native Custom codec is not used for update
• #184 Use Kotlin 1.70 with kotlinx.serialization 0.20.0
• Add Maven wrapper

• #175 String to BigDecimal deserialize
• #176 Expose KMongoSerializationRepository
• #177 Add ClientSession methods to RxJava2 implementation
• #181 Add positional operator shortcuts
• Object in polymorphic serializer throw Exception
• Support elemMatch for nullable iterable
• Check parent classes for Id property

• #161 add String.from and MongoOperator.from extensions for typed queries
• #162 generation for id property type not supported
• #165 typed queries: support of lookup operator
• Support nullable collection properties by "/"

The kotlinx.serialization mapping is now considered production ready. Look at the performance benchmark.

• #141 Remove kotlin-reflect dependency (see documentation )
• #154 register custom serializers for kotlinx.serialization
• #156 propagate create index exception in ensureIndex
• #157 Filter for enum value fails with Can't find a codec for class
• #158 improves kotlinx.serialization performance
• #159 kotlinx.serialization: support update without null properties

Thanks to the great kbson library of @jershell, KMongo now supports kotlinx serialization mapping!

This is an alpha release with some known limitations:

• You need to add the https://dl.bintray.com/jershell/generic repository in your configuration (see https://github.com/jershell/kbson/issues/8)
• no @BsonId support
• reflection is still used in some cases
• update with updateOnlyNotNullProperties = true is not yet supported (see https://github.com/jershell/kbson/issues/5)
• Maps with non primitive keys are not yet supported (see https://github.com/jershell/kbson/issues/6)
• Sets are not yet supported (see https://github.com/jershell/kbson/issues/7)
• no benchmark yet

Please report any issue ! :)
