	=== LMD ScriptPack 4.X ===		=== LMD ScriptPack 4.X ===

	[+] New PascalScript language is added. 100% Vcl native implemenation without external dlls. The PascalScript engine includes optimizing compiler to byte code and very fast byte-code interpreter. The PascalScript language is the dynamic Variant based script language that support most of the Delphi Pascal expressions and statements, procedure/function declarations, const/var/out parameters, global/locla variables and conatants. The PascalScript provides extended support of exception handling, e.g. raise, try-except and try-finally statements; real Delphi exceptions are raised internally that allows to testing exception class in handler, e.g. on E: EZeroDivide do. The PascalScript engine CodeObject implements the secret interface (in addition to IDispatch) that allows very fast interoperations between interconnected script controls; and also this interface allows to make transparent exception flowing between interconnected script controls. Native script operators such as 'is', 'in', '@' and set constructors, e.g. [akLeft,akTop], is able to work with imported from Delphi objects, instead of provided to ActiveX scripts special functions (e.g. SetMake, SetEmpty, ClassIs, EventMake, ect.).<br>

	[+] New three stage initialization of script control. Prepare, Open and Close methods and State property are added. So, the new 'Prepared' intermediate state become available. In this state all source code is already parsed, but no global code is executed yet. also the CodeObject is acessible in this state. This allows to make circular dependencies between script controls even in case when global code is used. In simple cases the call to Prepare method can be ommitted. Also the ACloseOnRuntimeError parameter is added to Open method to allow to leave script control opened in case on runtime errors while global code execution.

	~~[-] The notion of last script error has been complitelly removed from the script pack.~~

	[+] New exception formatting has been added instead of last-script-error concept. Now the script control includes the encoded source (reference to script control), error line and position information directly into exception message (e.g. in string form). The LMDDecodeErrorMessageInfo procedure allows to decode this information for advanced applications.

	[+] New extremely optimized Delphi memory manager proxy allows to detect wrapped object destructions. So, all subsequent access to IDispatch object wrapper will report 'Object has been destroyed' exception, instead of unsafe AccessViolation. This is especially actual for working with exceptions in PascalScript, because the exception objects are automatically destroyed by the interpreter.

	[+] New prepared expressions/statements feature is added to optimize Eval and ExecuteStatement methods. If the same expression/statement need to be executed many times then it is more efficient to Prepare it first and then use Eval and ExecuteStatement overloadeds methods that takes prepared objects as parameters. Note: the real efficiency gain will be only in the PascalScript because all other ActiveX scripts does not support ths feature internally.

	~~== LMD SyntaxEdit RoadMap ==~~
	* Nearest release (end of this January)
	[http://bts.lmd.de/mantis/view.php?id=567 Spellcheck support] using Addict (or other spellchecker using Windows RichEdit '''EM_*''' messages). <br> See [http://msdn2.microsoft.com/en-us/library/aa924582.aspx MSDN page on those messages]
	** [http://bts.lmd.de/mantis/view.php?id=570 Issue] with cursor position (and other significant TLMDEditView parameters) saving when it switches from/to different Documents. <br> Very useful for tabbed editing.
	** [http://bts.lmd.de/mantis/view.php?id=541 Back unindent] feature that aligns the cursor with the previous indentation level from the preceding line when pressing the 'Backspace' key
	** New word wrap [http://bts.lmd.de/mantis/view.php?id=569 mode] to wrap the text at the window width. <br> When window is resized, wrap is automatically adjusted to the new window width.
	** Cursor through tabs [http://bts.lmd.de/mantis/view.php?id=540 mode] so tabs can optionally be traversed with one right or left press of the cursor keys, regardless of tab width. <br> Visual Studio-like behaviour.
	** New option for cursor not to move beyond end of line.
	** New option in ViewSettings - Current line highlight enabling/disabling
	** Documentation update for features listed above, and implemented before, but undocumented.
	** And, hopefully, fix for [http://bts.lmd.de/mantis/view.php?id=542 replace issue] (it requires some structural changes in TLMDEditView)

	* Next release (approx., end of February)
	** Saving line+character position in items TLMDEditDocument.Bookmarks items (now, they are bound to line starts)
	** Custom colorization for Document's text postprocessing/highlighting (syntax errors, Firefox-like found text highlight etc). <br> Now, it exists in prototype, but, it requires optimization for large texts. <br> Planned API (functions in TLMDEditView/TLMDEditDocument):
	*** procedure AddCustomStyle(AStart, ACount: Integer; AStyle: TLMDEditViewStyle); <br> Adds custom style on some text range, over parsed syntax colorization.
	*** procedure RemoveCustomStyle(AStart, ACount: Integer; AStyle: TLMDEditViewStyle); <br> Removes given custom colorization layer from given text range.
	*** procedure ClearCustomStyles; <br> Removes all custom style layers from View.
	*** Here, TLMDEditViewStyle is object in View's CustomStyles collection. It contains color and font style.
	** New editor commands (sedDeleteToLineEnd, sedDeleteLine) etc. <br> All keybindings for commands now customizable with TLMDEditView.CustomKeyBindings collection. <br> Feel free to propose your commands... <br> Also, here i think on integration of standard VCL actions system with LMDEditView.CustomKeyBindings collection. <br> Feel free to send your ideas about that integration...
	* Releases after end of February will be focused on Parser improvements. <br> Here i plan:
	** Folding support for Ptyhon-like (indentation-based) languages
	** Visual syntax schemes editor
	** Improvements in syntax folding
	** Ability to generate names for folds, for syntax outline creation
	** Create separate Parser component for parsing/colorization external controls like TRichEdit etc.
