Web Client:

• Breaking change: expressions are now executed without waiting for all variables in them.
• Breaking change. The type Variable and other related types (such as StringVariable) are now classes, not interfaces. In most cases, all the code will work the same way, but in rare cases it may break something. Also note that it is now possible to check variable type with the instanceof, which works as a type-guard in TypeScript (getValue() will return a value with the correct type). Previously, this was not possible because only getType existed, and TypeScript would not use it as a type-guard.
• Breaking change: private methods in DivKit instance was removed. This methods was not typed and was not documented.
• Breaking change: added arrows for pager on the desktop platform. There are new customization options for these arrows. Also note that the platform can be configured using the render method.

• Added try operator !: for expressions.
• Undeclared variables would not cause expressions to fail (even without getting their values) (revert change from version 23.4.0). The error would still occur if the expression actually evaluated an undeclared variable.

• Fixed an issue with the expressions support inside transition_change property.
• Fixed an SSR error that occured when rendering a card with a list of timers.
• Empty containers (without items) is now allowed.

• text component with an empty text property is now allowed.
• Fixed an issue with whitespace near brackets () in expressions.
• Added a new experimental method setData. This method allows you to quickly redraw the DivKit card using a new json, much more efficiently than directly destroying and recreating it again.
• Fixed possible errors in integer calculation for the functions getArrayInteger, getIntegerFromArray, getArrayOptInteger, getOptIntegerFromArray, getDictInteger, getIntegerFromDict, getDictOptInteger, getOptIntegerFromDict, copySign.
• Fixed an issue with a separators in container in the ssr mode.

Web Client:

Breaking changes:

• The setVariable / GetVariable methods have been removed (these methods were deprecated long time ago before opensource, in web version 1.11.0)
• DivKit now uses BigInt internally if it is supported by the current platform. This also means that variable methods such as subscribe can now return bigint values instead of number (and accept such values in json). integer values in expressions are now limited to 64 bits instead of 32, and the minimum/maximum value for integer variables has been changed. Note that outside of expressions, DivKit restricts values to 32-bit integers, as was the case in previous versions. Also note that the js builtin methods, such as JSON.parse, return a simple number, so these values may lose accuracy outside the logic of DivKit. Make sure that your values are in the range -2^53 — 2^53 or a custom json parsing function is used

• doubletap_actions and longtap_actions are now supoorted in actionable components
• Support for the appearance_animation in image
• Support for the restrict_parent_scroll property in tabs, gallery and pager
• Root states are now properly supported Changes and fixes:
• Updated the wrap_content logic, this would lead to a different layout in some corner-cases
• Boolean values from exressions are now correctly converted to the string false / true in the text block
• The layout of the slider has been changed to sync with other platforms, now the text offset will not change the size of the component. Also now there may be more than 20 ticks
• Updated color functions according to the latest changes. Now several of them would return the type color instead of string (rgb, rgba, setColorRed and others)
• Components will now correctly unregister when destroyed, so recreated elements will work properly (for example, actions to change the current element in the gallery, nested state elements and others)
• Fixed logic of expression processing Previously, if a string was considered an "expression", it was processed as it, otherwise it would be used as a simple string. But sometimes this check worked incorrectly and processed expressions as a string. This is now fixed. It also means that some strings will now require proper escaping, so be sure to check this in your project (previously,these strings "just worked" without escaping because they were not treated as expressions)
• Now elements with custom actions can be focused, as it was with simple URLs. This would result to better accessibility in such cases (these elements also accept the keyboard input!)
• Fixed the visibility of the gallery arrows on desktops in several cases
• Fixed a case wheretransition_in, transition_out and transition_change incorrectly discarded the alpha component property
• Component actions will now wait for the result of each of them. This means that you can create an array using 2 actions: one to change the state, and the second to change the created component inside the state
