Market 
- Another new product category has been added to MetaTrader 
AppStore following trading and financial magazines - Books. Now, you can
 purchase the works of well-known traders and analysts along with 
trading robots and indicators. The range of books is increasing daily.
 
  
 
 Just like MetaTrader 5 applications, books can be purchased at 
MQL5.community Market as well as directly via MetaTrader 5 terminal. All
 books are accompanied by descriptions and screenshots:
 
  
 
 
 Before making a purchase, you can download a preview - the first few
 pages of a book. The exact number of available pages is defined by a 
seller.
 
 To buy a book, you should have an MQL5.com account and the necessary
 amount of funds on it. The account data should be specified at the 
Community tab of the terminal settings:
 
  
 
 Click Buy on the book's page to purchase it. Purchase confirmation dialog appears:
 
  
 
 To continue, agree to the rules of using the Market service and 
enter your MQL5.community password. After that, the specified amount of 
funds will be withdrawn from your account and the book will be 
downloaded. Buy button will be replaced by Open one.
 
 Book files are downloaded to My Documents\MQL5 Market\Books\. The download may be performed in two formats:
 
 - MQB - this protected format is used for paid books.  When 
purchasing and downloading a book file, it is encoded so that it can be 
opened only on the PC it has been downloaded to. Generation of an 
encoded copy is called activation. Each book can be activated at least 5
 times on different hardware. Book sellers can increase the number of 
activations at their sole discretion.
- PDF - this format is used for free books and previews. After downloading, such file can be moved and viewed on other devices.
 
 The special component called MetaViewer has been added to MetaTrader
 5 terminal allowing users to view book files. MetaViewer is a 
convenient application for viewing books and magazines in MQB and PDF 
formats. Keyboard arrows are used to turn over the pages: left and right
 arrows - for page-by-page navigation, while up and down arrows - for 
scrolling.

MQL5 Language
- Changed StringSplit function operation. Previously, ";A;" 
string was split into NULL and "A" substrings using ';' separator. Now, 
it is split into "","A" and "" substrings.
- Fixed checking and tracking parameter and operand constancy.
Trading Signals
- Added additional checks for the allowed trading modes at a
 symbol when copying signals. If a signal arrives at a subscriber's 
account but only closing of positions is allowed at that symbol, this 
will no longer cause complete termination of signals copying and forced 
closing of all positions. Now, if a signal for position opening arrives 
at a subscriber's account, the platform perceives that as the command to
 synchronize subscriber's and provider's accounts. A signal for position
 closing is handled as usual.
Strategy Tester
- Added interface translations into French, Japanese and
 Arabic. Updated translations into German, Italian, Polish, Portuguese, 
Russian, Spanish, Turkish and Chinese.

 Previously, the tab characters were ignored and string content was 
displayed with no spaces.
Fixed errors reported in crash logs.
