Breaking Changes

• Images will be loaded from an external source (e.g. http://example.com/img.png) only if the reader is explicitly set to allow it via $reader->setAllowExternalImages(true). We do not believe that loading of external images is a widely used feature.
• Deletion of items deprecated in Release 4. See "removed" below.
• Move some properties from Base Reader to Html Reader. PR #4551
• DefaultValueBinder will treat integers with more than 15 digits as strings. Issue #4522 PR #4527

Removed

• Theme public constants COLOR_SCHEME_2013_PLUS_NAME (use COLOR_SCHEME_2013_2022_NAME) and COLOR_SCHEME_2013_PLUS (use COLOR_SCHEME_2013_2022).
