+includes new letters and some corrections:
 
-Notes
------
-[^1]: https://github.com/akryukov/oldstand
+1. Small capitals for Roman, Greek and Cyrillic letters, in all three
+   styles, Regular, Italic and Bold have been added. Small capitals,
+   which are missing from *Old Standard*, were already in use a
+   century ago in fine books which used font faces very similar to
+   *Old Standard*. Typical use cases of small capitals were headers,
+   current headings and in some books proper names.
+2. The letter G with caron above, that is: Ǧ (`U+01E6`, uppercase) and
+   ǧ (`U+01E7`, lowercase) has been added. It is the only character
+   missing from *Old Standard* that is needed in some of the accepted
+   standards of romanization of classical Arabic.[^2]
+3. Additionaly, *Old Standard T* corrects `+ss06` feature provided by
+   *Old Standard*. This feature is supposed to distinguish between
+   regular and ‘curly’ beta (β/ϐ) and to print ‘curly’ beta (`U+03D0`)
+   in medial position. This feature works in most cases with *Old
+   Standard*. However, it fails if the beta is preceded by a vowel
+   with an acute accent taken from the *Greek extended* Unicode block.
+
+### Why *Old Standard T*?
+At the time of writing, *Old Standard* was last updated six years
+ago. Nevertheless, the letter `T` stands for *Transient*, which means
+that *Old Standard T*, should only stay as long as what it features is
+not included in *Old Standard*.
