 * [`FPDF.write_html()`](https://py-pdf.github.io/fpdf2/fpdf/fpdf.html#fpdf.fpdf.FPDF.write_html): now parses `<title>` tags to set the [document title](https://py-pdf.github.io/fpdf2/fpdf/fpdf.html#fpdf.fpdf.FPDF.set_title). By default, it is added as PDF metadata, but not rendered in the document body. However, this can be enabled by passing `render_title_tag=True` to `FPDF.write_html()`.

 ### Fixed
 * support for `align=` in [`FPDF.table()`](https://py-pdf.github.io/fpdf2/Tables.html#setting-table-column-widths). Due to this correction, tables are now properly horizontally aligned on the page by default. This was always specified in the documentation, but was not in effect until now. You can revert to have left-aligned tables by passing `align="LEFT"` to `FPDF.table()`.
 * `FPDF.set_text_shaping(False)` was broken since version 2.7.8 and is now working properly - [issue #1287](https://github.com/py-pdf/fpdf2/issues/1287)
