In the past, incorrect usage would not be caught, leading to difficult bugs. This means that incorrect usage of FreeAndNil will now cause a compiler error. Procedure FreeAndNil ( const Obj : TObject ) inline The new default is 1MB, but the method has an additional parameter you can use to provide a specific buffer size depending on the copy operation you are doing (source and target streams). This can be very inefficient for copying large streams. The CopyFrom function of TStream used to have a fixed constant buffer for copying data (set to 60K).We have removed some dependencies blocking certain console apps to run on WindowsServerCore.Optimized assigning a sorted StringList to another StringList.The Items property of TJSONArray is now a default array property, allowing you to write myJArray rather than myJArray.Items.JSON reading optimization: TJSONReader is now 50% faster.New TCustomIniFile methods WriteInt64 and ReadInt64.
