UX/Dash

Added an optional check for AutoHotkey updates, disabled by default. [based on AutoHotkey/AutoHotkeyUX#11 by kczx3]
Fixed errors being raised when arrow keys are used in the Help Files menu. [AutoHotkey/AutoHotkeyUX#24 by iPhilip]
Fixed install-version.ahk to delete the temporary ".staging" directory after installing an upgrade.
Fixed Help Files menu to be displayed at the button, not at the mouse cursor.
Changed "New script" to add the file to recent files.

Changed how key-up events are correlated to key-down events for the purpose of determining whether to suppress key-up. A key-down with SendLevel between 1 and 7 now only correlates with a key-up of the same level. When #InputLevel 1 is in effect, this fixes Right::Send "{Right}" not suppressing key-up, RShift::RAlt interfering with RAlt::RShift and vice versa. Events with SendLevel 8 and above are still grouped with non-sent events for practical reasons.

Fixed WinExist("A",,,"B") to not exclude windows which have no controls.

Fixed custom combo hotkeys with neutral modifiers (e.g. Alt & Esc::) [broken by v2.0.22].

Fixed key-up hotkeys to fire consistently when the key is used as both a prefix and a suffix (e.g. a & b::, b & a:: and a up::).

Fixed timers interrupting MsgBox after the timeout starts but before the window is shown, such as if SetTimer(MsgBox, -10) is used immediately before MsgBox(1,,"T1").

Removed the undocumented effect that a hotkey with the </> prefix had on the corresponding modifier key; e.g. <^a:: causing LCtrl:: to fire on release, inconsistent with the documentation. Always firing on press provides greater consistency and flexibility. The modifier key itself was suppressed since v2.0.20. Neutral modifiers such as Ctrl:: always fire on release, and similar behaviour can be implemented with A_PriorKey and ~LCtrl up::.

Changed error dialogs to use msftedit.dll instead of riched20.dll to fix the following issues:

• Hanging when inspected by UI Automation.
• Broken characters and inconsistent fonts when the error message includes certain character sets (e.g. emoji, Chinese or Arabic).

Fixed errors within __Delete being suppressed if a Try/Catch is active.

Fixed CallbackCreate to validate ParamCount.

Fixed detection of DllCall(... "str",&var:={} ...) as an error.

Fixed CapsLock:: to suppress even if CapsLock is used as a prefix key.

Fixed neutral Ctrl/Alt/Shift hotkeys to not suppress the key [broken by v2.0.20].

Fixed fire-on-release behaviour of neutral Ctrl/Alt/Shift hotkeys when a key-up variant is turned on but disabled by #HotIf.

Fixed CapsLock & 1:: to revert CapsLock state even if another prefix key is pressed before CapsLock is released.

Fixed L/R modifier key-up not being suppressed in some cases where key-down was suppressed.

Fixed L/R modifier key-up to be passed through if ~ is used even if key-down was suppressed.

Fixed L/R modifier hotkeys to fire on press even if the corresponding neutral modifier is present; e.g. LCtrl:: with Ctrl::.

Fixed corruption of unquoted continuation sections with trailing spaces.

Fixed file stream I/O to flush cached writes if the file hasn't been closed when the process exits.

Fixed `; in contination sections with the ` (literal escape) and C (comment) options.

Cleaned up some code within the keyboard/mouse hook.
