-- Improved library performance,
-- Breaking change: changed default font from Calibri to an open-source Lato,
-- Default font files are included with the nuget package, making it safe to deploy on any environment,
-- Default font files are significantly smaller, so output document files should be smaller too (up to 20x reduction in size),
-- When requested font is not available on the runtime environment, library provides list of available fonts,
-- Fixed a rare layout overflow exception with the Inlined element,
-- Fixed a memory leak connected to the HarfBuzz library.

+## Please share with the community
+
+As an open-source project without funding, I cannot afford advertising QuestPDF in a typical way. Instead, the library relies on community interactions. Please consider sharing a post about QuestPDF and the value it provides. It really does help!

 QuestPDF is an open-source .NET library for PDF documents generation.
 
-It offers a layout engine designed with a full paging support in mind. The document consists of many simple elements (e.g. border, background, image, text, padding, table, grid etc.) that are composed together to create more complex structures. This way, as a developer, you can understand the behavior of every element and use them with full confidence. Additionally, the document and all its elements support paging functionality. For example, an element can be moved to the next page (if there is not enough space) or even be split between pages like table's rows. All of it done with predictable and discoverable Fluent API.
-
-## Installation
-
-The library is available as a nuget package. You can install it as any other nuget package from your IDE, try to search by `QuestPDF`. You can find package details [on this webpage](https://www.nuget.org/packages/QuestPDF/).
