+This files describes API changes in /dataformat/ download system,
+information provided here is intended especially for developers.
+
+=== 3.11.1 ===
+* Optional $callback for the following \core\dataformat methods now receive a second argument to define
+  whether the current format writer supports HTML:
+  - download_data()
+  - write_data()
+  - write_data_to_filearea()
+
+=== 3.9 ===
+* The following methods have been added to the base dataformat class to allow instances to export to a local
+  file. They can be overridden in extending classes to define how files should be created:
+  - start_output_to_file()
+  - close_output_to_file()
+* Calls to the following dataformat plugin methods have been removed:
+  - write_header()
+  - write_footer()
+* The following methods have been added to the base class to allow instances to define support for exporting
+  HTML content, with additional support for defining how images should be embedded:
+  - supports_html()
+  - export_html_image_source()
+* Dataformat writers should also call the following method to ensure data is properly formatted before being
+  written, which takes into account prior methods defining support for HTML:
+  - format_record()
+
+=== 3.4 ===
+* In order to allow multiple sheets in an exported file the functions write_header() and write_footer() have
+  been removed from core dataformat plugins and have been replaced.
+  - write_header() has been replaced with the two functions start_output() and start_sheet().
+  - write_footer() has been replaced with the two functions close_output() and close_sheet().
+  For backwards compatibility write_header() and write_footer() will continue to work but if used will
+  trigger the function error_log().
+
+=== 3.1 ===
+* Added new plugin system with low memory support for csv, ods, xls and json
