NotifyRecentInfoUpdate and NotifyQuotesUpdate methods of DataSourceBase use PostMessage Windows API calls instead of SendMessage. PostMessage is asynchronous and this change prevents blocking plugin threads by the main AmiBroker UI thread.
QuotationList class provides ICollection interface
Note: because of ICollection interface "public virtual void Remove(Quotation quote)" method signature changed to "public virtual bool Remove(Quotation quote)" This may require to recompile custom data sources.
Quotation.Merge can merge negative Volume data.

AmiBroker.Data.QuotationList class supports mixed intraday and EOD quotes. Inheritance from List is removed. Indexer and all other needed methods are still available.
AmiBroker.Data.QuotationList.Add() is depricated
AmiBroker.Data.QuotationList.Merge() method collects and builds intraday quotes of proper periodicity. E.g. 5 min bar data can be built by passing in RT tick data as they arrive in the data stream. If an intraday quote is passed in, it is either added as the last intraday quote (added to the end of the quote list or inserted before the EOD quote if EOD exists) or merged into the last intraday quote based on the time of the quote and periodicity of the list. If an EOD quote is passed in, it is inserted ot if the EOD quote already exists, it is updated. Intraday quotes must be passed in in their order. EOD quotes can be passed in any order.
AmiBroker.Data.QuotationList.MergeEod() method collects and builds EOD quotes. Intraday quote is merged into the EOD quote for the trading date. EOD quote is inserted or if the EOD quote already exists, it is updated. Intraday quotes must be passed in in their order. EOD quotes can be passed in in any order.
AmiBroker.Data.AmiDate struct supports EOD quotes.
New const properties: FutureMask, EodMask
New properties: IsEod, IsFuture
Obsolete properties: IsFuturePad
Explicit casting to and from DateTime can handle EOD quotes. Time part of the DateTime of an Eod quote is 23:59:59.999
AmiBroker.Data.QuotationArray.Merge() function's logic is fixed to handle huge number of quotes (more then the size of the array and earlier than the first quote in the array)
AmiBroker.Data.Quotation class has a ToString() method for better debugging support.
AmiBroker.Data.Quotation class has a Merge() method to merge H, L, C, V data of two quotes.
Unmanaged dll files in Assemblies folder are handled more gracefully. An error message of " is not a .NET plug-in assembly. HResult: " is written to the instance log instead of BadImageFormatException.
64 bit version
The very same .NET plug-in dlls can be used for both 32 bit and 64 bit AmiBroker. There is no need to develop different dlls.
.NET for AmiBroker (x64) is available only in Developer and Standard Edition and uses the same license keys as 32 bit version.
Interactive Brokers data source (AmiBroker.DataSources.IB.dll)
It can download 1 year of historical data of any time period.
It can download historical and capture real time quotes of any type of securities (stocks, options, futures, etc.)
Interactive Brokers data source plug-in is updated to have compatible symbology with IB.dll (original AmiBroker data plug-in)
Logging of IB/TWS messages and trace messages can be disables.
New Symbol format has changed to support all security types:
// SYMBOL FORMAT:
// symbol[-exchange[-security type[-currency[:data specifier]]]]
//
// SYMBOL:
// TWS ticker symbol in symbol mode. Right click on the TWS page, select Contract Dispaly Mode menu, select Symbol Mode menu.
// Some symbol includes spaces. Spaces must be retained. E.g.: "YM SEP 11". Must include all 4 spaces!
//
// EXCHANGE:
// See IB site. E.g.: SMART, NASDAQ, NYSE, IDEALPRO, IDEAL, etc.
//
// SECURITY TYPES:
// STK = Stock, OPT = Option, FUT = Future, IND = Index, FOP = FutureOption, CASH = Cash, BAG = Bag, BOND = Bond,*/
//
// CURRENCY:
// use 3 letter currency specifiers. E.g.: USD, EUR, AUD, etc.
//
// DATA SPECIFIERS:
// A = Ask, B = Bid, BA = Bid and Ask, T = Trades, M = Midpoint
//
// DEFAULTS:
// exchange: SMART
// security type: STK
// currency: USD
// data specifier: MIDPOINT for CASH; TRADES for all other
//
// E.g:
// --- FOREX ---
// EUR.USD-IDEALPRO-CASH:M
// EUR.USD-IDEALPRO-CASH
//
// --- STOCK ---
// MSFT-SMART-STK-USD:T
// MSFT-SMART-STK-USD

// YM SEP 11-ECBOT-FUT
Instance logging
The CLR host component created a new log file in the ".NET for AmiBroker\Logs" folder for each running instance of AmiBroker. All the startup messages and user code log messages are written to these files. Log file (.csv) can be easily parsed in any text editor or in Excel. Log files older then 10 days are automatically deleted.
.NET plug-ins (IndicatorBase.DotNetLog static method) and AFL scripts (DotNetLog method) can send log messages to these files.

AFL editor can show .NET plug-in method signature. AFL signatures are generated automatically from ABParameter attributes or .NET plug-in method signatures. E.g.:
MyFunc2(Description of param1, Description of param2 = 5)
MyFunc1(String, String)
A single Setup utility is created for all software editions.
Installed software edition can be changed any time by running the setup utility.
No need to restart the computer after installation.
