AutoHotkey 2.0.21 + Portable

Fixed memory out-of-bounds access during RegEx compilation.

Fixed externally-released modifiers to not be "restored" post-Send.

Fixed modal dialog boxes suppressing InputHook events.

Fixed key-up erroneously being suppressed after key-repeat presses it down in some cases.

Fixed Critical Error when loading large icons with no alpha channel.

Fixed MouseGetPos to make Control blank and not throw if ClassNN cannot be determined.

Fixed FileSelect to validate Options.

Fixed unexpected Catch/Else/Finally/Until not being flagged as an error in some cases.

Fixed Try/Catch/Else/Finally not executing Finally if Else returns.

Fixed execution of if-else-if-else-if containing fat arrow functions.

Fixed A_Clipboard silently exiting when GetClipboardData returns NULL.

Fixed a.b[c] := d to invoke the getter for a.b if there is no setter.

Implemented an optimization to the WinText parameter by Descolada. [PR #335]

Changed UnsetError message to suggest a global declaration instead of appending "(same name as a global)" after the variable name.

Changed VarUnset warning message for consistency with UnsetError.

Fixed the increment/decrement operators to throw UnsetError if the var is unset, not TypeError.

Fixed OwnProps to assign the property name safely in cases where a property deletes itself.

Fixed breakpoints to work in arrow functions under a control flow statement without a block.

Fixed debugger to break at the line of the call when stepping out of a function. (This behaviour was added in Revision 31 and broken by v1.1.30.00.)

Stepping out of a function which was called as a new thread now breaks at the line which was interrupted, instead of waiting until the next line is reached.

Fixed debugger to not delete temporary breakpoints which are ignored while evaluating DBGp property_get or context_get.

Fixed DBGp property_get failing to retrieve properties due to incorrect paging (since v2.0.14).

Fixed DBGp property evaluation causing Try without Catch to fail (since v2.0.14).

Fixed <base> debugger pseudo-property leaking a reference (since v2.0.14).

Changed Hotkey function to throw ValueError if Options contains an invalid option.

Fixed InputHook to respect the +S option for Backspace when acting as undo.

Fixed debugger to safely handle property deletion during enumeration.

Fixed OLE clipboard content (e.g. error dialog text) being lost on exit.

Fixed detection of invalid suffix on a hotkey, such as Hotkey "a pu".

Fixed DllCall AStr* arg type to copy back only if address changes.

Fixed #Include to correctly "close" any built-in variable it reads (no known impact on real-world scripts).

Fixed WinTitles with two different ahk_id values to yield no match.

When I run the portable x64 version I get the following error:

Script file not found.
C:UsersUserDownloadsAutoHotkey_2.0.12AutoHotkey64.ahk

How to solve?
Thanks

Fixed Gui GetPos/GetClientPos when Gui has an owner window or +DPIScale.

Fixed Until preventing subfolder recursion in file loops.

Fixed DllCall to throw when arg type is UStr.

Fixed a memory leak occurring for each regex callout.

Fixed Send erroneously releasing a modifier due to a race condition. For example, ~LAlt::Send "{Blind}x" intermittently released LAlt if some other keyboard hook was installed more recently than the script's own hook.

Fixed icon loader to prefer higher bit-depth when multiple bitmaps of the same size are present.

Fixed SendInput failing to release LCtrl if it had already released RAlt and the layout does not have AltGr.

Fixed key-up hotkeys not firing if the key repeats after modifiers change. For example, F1::Send "{Ctrl down}" should allow F1 up:: to execute when the key is released even though Ctrl is down, but was not allowing it after key-repeat occurs.

Fixed an error message to refer to #HotIf rather than #IfWin. [PR #327]

Fixed OwnProps erroneously skipping properties with optional parameters.

Fixed inconsistent behaviour of cloned dynamic properties.

OwnProps not skipping cloned properties which require parameters.
Parameters not being passed recursively to parameterless properties (i.e. to allow a.b[c] to evaluate as (a.b)[c]).
Fixed SysGetIPAddresses causing a Critical Error when the network subsystem is non-functional; e.g. in Windows safe mode.

Changed ControlGetFocus to return 0 when focus can't be determined, such as when a console window is active.

Added a workaround for the first shown menu not accepting keyboard input on Windows 10.

Fixed the Add method (Gui) to support the ShortDate option for DateTime controls.

Fixed a reference counting error with multi-level function nesting.

Fixed #include <x> causing a load-time crash if used inside a function.

Fixed ListView.Opt("NoSort").

Fixed a memory leak occurring when an object with no own properties is cloned.

Fixed #include and FileInstall (non-compiled) to compare file names ordinally, not linguistically.

Fixed crashing when a named function hotkey is used after #HotIf.
Fixed numeric literals ending with a dot to not cause line continuation.
Fixed pre-increment/decrement to work with chained array indexing.
Fixed OnNotify/OnCommand applying styles only applicable to OnEvent.
Fixed FileExist/DirExist leaking handles when emptydir* is used.
Fixed DirExist leaking handles when only files match.

Fixed stacking of hotstrings with the X option.
Fixed debugger not listing local vars if the function is at the bottom of the stack.
Fixed Gui threads to show on the debugger's call stack.
Fixed some combinations of &/ByRef causing stack overflow in ExitApp.

Fixed ByRef parameters erroneously assigning the default value to the caller's VarRef if unset.

Fixed some issues affecting suppressed Alt/Ctrl/Shift/Win hotkeys, such as:

*LCtrl:: blocked LCtrl from the active window, but sending Alt-key combinations would fail because the system thinks Ctrl is down, and would therefore send WM_KEYDOWN instead of WM_SYSKEYDOWN.
*LAlt:: caused the system to forget any prior {LAlt DownR}, so a remapping such as LCtrl::LAlt would not behave correctly while LAlt is physically down, even though LAlt was suppressed.
Other potential issues where the system's low-level tracking of a modifier key doesn't match up with the logical state.
Fixed some issues affecting continuation sections:

Escape sequences in the Join option were translated twice, causing ```` to become one literal ` instead of two, ``n to become a linefeed, and similar.
`" or `' produced a literal backtick and ended the string, instead of producing a literal quote mark, if the continuation section was enclosed in quotes of the same type and lacked the ` option.
Optimized the automatic escaping of quote marks and backtick in continuation sections.

Fixed breakpoint_list (debugger) returning duplicates on lines containing fat arrow functions.

Fixed +BackgroundDefault failing to override the Gui's BackColor property.

Fixed MouseClickDrag to allow X1 and Y1 to be omitted.

Fixed mouse AltTab hotkeys not suppressing execution of a prefix hotkey, such as 1:: for 1 & WheelDown::AltTab. (Broken by v2.0.4)

Fixed hook hotkeys not recognizing modifiers which are pressed down by SendInput.

Fixed A_AhkPath to not be reliant on the case/format of the command line used to launch the process.

Fixed heap corruption during window searches involving groups. (Broken by v2.0.6)

Launcher

Fixed #Requires not being detected if followed by a comment other than ; prefer xxx. (Broken by v2.0.6)

Fixed syntax detection misinterpreting multi-line auto-replace hotstrings.

Window Spy

Changed font to Segoe UI size 9, consistent with Dash.

SHA256 hash

Fixed some ambiguity with COM calls, such as x.y acting as x.y().

Fixed breakpoint on control flow statement being "hit" when a fat arrow function on the line below it returns.

Fixed Default : to not merge with the line below it. This prevented Default : from being used at the end of a Switch block, and caused any subsequent line to take the line number of the Default.

Optimized ProcessGetPath, ProcessSetPriority and ProcessClose to not scan through all processes when given a valid PID, even if access to the process is denied.

Fixed inability of LWin::Alt to be used to activate some Alt key combos.

Fixed TypeError thrown by x is y to say "Class" rather than "Object".

Fixed WinTitle to support criteria longer than 1023 characters.

Fixed issues when &ref is used on different aliases of the same variable.

Fixed optional parameter default expressions (other than simple literal values) preventing the use of assume-global/assume-static.

Fixed Hotkey("a", "b") to use the original function of "b", not "a". [PR #318]

Fixed FileSetAttribute crash when used in a File Reading Loop. [PR #323]

Fixed duplicate Gui control name errors to correctly abort the thread.

Fixed DateTime/MonthCal Range option not applying minimum value.

Fixed s[x] => x and other single-line properties starting with "s".

Fixed a bug with deleting a breakpoint on a static line containing =>.

Fixed Button control not becoming default when clicked.

Fixed PixelSearch to unset X when pixel is not found.

Fixed hotstring with escape sequence causing next line to be skipped.

Fixed WinTitle ignoring character 1 when "ahk_" is at character 2.

Fixed remapping to utilize right-hand modifier already being down. For example, +x::+y will no longer release RShift to press LShift.

Changed error message for a == b && c() and similar cases to avoid alluding to legacy =.

Improved error message for some cases of unintended line continuation.

Fixed reserved words to be permitted as method names, as documented.

Fixed duplicate onmessage calls for some keyboard messages.

Fixed inter-referenced closures being deleted prematurely.

Fixed SetFont to permit leading spaces in the Options parameter.

Fixed sending of {ASC nnnn}.

Fixed a.base := a to throw an error.

Fixed x.y := unset causing crashes or undefined behaviour.

Fixed GuiControl.Move() to be relative to the GUI's client area even when the GUI is not its parent.

Fixed Menu Add overwriting items which were appended by Menu Insert.

Fixed Short DllCall arg type and undefined behaviour for invalid types.
Fixed (non-string) file version number for AutoHotkey binaries.
Fixed parameter type errors to show the correct parameter number.
