Several bugs encountered in 579. So far:
1. Using Tools->Options->Email tab, I configured it with my usual settings that work fine on 509, but click "Test" and it fails. Journal says "login to smtp... failed", but I'm certain it's correct server/login/password. No Email is a BIG bug for me.
2. Old scripts that use PlaySound ( For example: 'PlaySound("alert2");' ) don't work. The .ex4 files are NOT forward compatible. They work if recompiled.
3. This one is almost cosmetic, so no big deal: My code has global variables that are repeated as arguments in function definitions, so I get a proper warning:
declaration of 'gvar' hides global declaration at line 9
The bug is that it isn't on "line 9" but rather on "line 18". The hyperlink to the error works, and the correct line# and char# is listed to the right of the error message.
Service tickets filed for each.
FYI, as another user reported, my production "P4L Clock" program doesn't work anymore. Re-compiling wasn't the fix. Fortunately, there is a solution. In 509, the label objects -- regardless of the order in which they were created -- drew on the chart in alphabetical order. I took advantage of that to create labels that were merely rectangles that covered up the price bars beneath it, to give me a blank slate in the corner, so to speak. Then I put labels on top of my background label(s). I controlled the 1st letter of the labels ObjectName to get it to display properly.
The alphabetical phenomenon is "broken" in 579. Labels appear to draw in the order in which the objects were created. Therefore, I have to create the background labels first, and the labels that go on top afterwards. So far it seems to work.
My expert displays a vertical list with earnings of each order,
And the end result of the Equity, by function comment ().
The results are normalized to a decimal.
But randomly fails function NormalizeDouble and function DoubletoStr .
And it shows a long list of 15 decimal, in this format:
23.499999999999999 or 23.400000000000001
Great work MetaQuotes.
Congrats to the guy who decided to upgrade MT4.
Yes there are still some bugs, but this is the right way.
I've converted my 4k lines software in new version and it works fine.

It was fixed. Please wait for the next build.
Build 579
Still doing the same (the indicator has to be attached to the chart when you restart the terminal - it happens when it is attached to the chart and the terminal is restarted) Here is one simpler example (that displays the value of such a string parameter to the chart - just attach it and restart terminal).
We are investigating this issue.
If any one is still interested with weird behaviour... this time it is about indicators.
Have you written something into servicedesk about this issue?
If you haven't, please write it including sources and step-by-step description.

No, I did not, the first one I do not care, I always use the strict option, the second I will take care of in code as well and the third issue appeared only in the 577 alone and was cured in 578.
Ah, well spotted, thanks. I would consider moving to be processing . . . I guess I'll have to test it.
The files, directories and subdirectories in the basic structure will be copied recursively, so do not worry. I tested it.
Before upgrade:
experts\files\12\a.csv
experts\files\12\b.csv
experts\files\12\99\1.csv
experts\files\12\99\2.csv
experts\files\12\99\3.csv
After upgrade:
MQL4\Files\12\a.csv
MQL4\Files\12\b.csv
MQL4\Files\12\99\1.csv
MQL4\Files\12\99\2.csv
MQL4\Files\12\99\3.csv
The same applies to all other standard files and directories inside old experts\ directory.
I've Windows 7, UAC turned off. I guess the same applies to UAC on, but it has to be tested by someone else.
Maybe I'm misunderstanding . . . MetaQuotes CEO said . . . "old ex4/mq4 files will work, " if the .hst format has changed how can this statement be true ?
"All old EX4 will work in the new MetaTrader 4 terminal".
This is clearly not true. Not only will those calling offline charts not work, but other EAs I've got are not working either, not in as old .ex4. and certainly not when recompiled with the new (now at 582 ver).
So much language has changed, and old language is not being recognized.
Where is all this documented, e.g., 'extern' appears to be replaced by 'input', start replaced by 'ontick'.
Where is the documentation for all this? e.g. change this to this?
