 - Fonts:
-  - Added AddFontDefaultVector(): a new embedded scalable font!
-    Based on ProggyVector by Tristan Grimmer, the same author as our good-old ProggyClean.
-    The font data was carefully subsetted, trimmed and compressed so the embedded
-    data is ~18 KB. Embedding a scalable default font ensures that Dear ImGui can
-    be easily and readily used in all contexts, even without file system access.
-    As always you can opt-out of the embedded font data if desired. A sizing tweak
-    was also applied to ensure the new font is a closer match to the classic font.
+  - Added AddFontDefaultVector(): a new embedded monospace scalable font: ProggyForever!
+    From https://github.com/ocornut/proggyforever:
+      "ProggyForever is an MIT-licensed partial reimplementation of the ProggyVector
+       font (originally by Tristan Grimmer), which itself is a vector-based
+       reinterpretation of the ProggyClean bitmap font that happily served as
+       Dear ImGui default font for over 10 years." [...]
+      "I commissioned Thiebault Courot to recreate this, applied various minor tweaks
+       and fixes, and reworked his editing pipeline toward shipping FontForge source
+       files so we can allow and track future changes."
+    - TL;DR; there was no strictly MIT-licensed matching font. We made it!
+    - The font data was carefully subsetted, trimmed and compressed so the embedded
+      data is ~14 KB. Embedding a scalable default font ensures that Dear ImGui can
+      be easily and readily used in all contexts, even without file system access.
+    - As always you can opt-out of the embedded font data if desired.
   - AddFontDefault() now automatically selects an embedded font between
     the classic pixel-looking one and the new scalable one.
+    Prefer calling AddFontDefaultVector() or AddFontDefaultBitmap() explicitely.
   - Fixed an issue related to EllipsisChar handling, while changing
     font loader or font loader flags dynamically in Style->Fonts menus.
   - imgui_freetype: fixed overwriting ImFontConfig::PixelSnapH when hinting

 We embed fonts in the code so you can use Dear ImGui without any file system access.
-If you use either of those fonts in your shipping product you should include their license as part of your software (see below for links).
 If you don't use them you can set `IMGUI_DISABLE_DEFAULT_FONT` in your [imconfig.h](https://github.com/ocornut/imgui/blob/master/imconfig.h) file to ship binaries without the fonts and save about ~26 KB.

 Omar: "I first discovered the IMGUI paradigm at [Q-Games](https://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it."
