+# What's new in babel 3.84
+<span style="color:red;">⚠</span> There are some issues with the
+new `\MakeUppercase` and `\MakeLowercase`. For further details, see:
+[Localization of \MakeUppercase and \MakeLowercase broken](https://github.com/latex3/babel/issues/189)
+## Encodings with pdftex and `\babelprovide`
+With `pdftex`, when a language is loaded with `\babelprovide`,
+selectors now set the font encoding based on the list provided when
+loading `fontenc`. This mechanism has been devised primarily for
+words or short texts in other languages loaded on the fly (although
+with RTL scripts you still need `bidi=default`), and it’s, in some
+sense, the equivalent in this engine of the automatic setting of
+language and script in `xetex` and `luatex`.
+The rules for the assigned encoding are the following:
+* If the valid encodings as set in the `ini` file contain the main font
+  encoding, use this one.
+* Otherwise, select the first encoding set in the `ini` file and
+  declared with `fontspec`.
+You can customize its behaviour in several ways:
+* Disable it altogether with `\babeladjust{ encoding.select = off }`.
+* Modify the encoding list in the `ini` file with
+  `identification/encodings =` in `\babelprovide` with a space
+  separated list, by order of preference (of course, this is not
+  possible with locales loaded on the fly).
+A simple example is the following:
+\usepackage[T2A, LGR, T5, T1]{fontenc}
+English \foreignlanguage{greek}{Ελληνικά} English.
+Български \foreignlanguage{vietnamese}{Tiếng Việt} български.
+## New option `layout=counters*` 
+The option `layout=counters` redefines some counters for they to be
+printed in the correct order. Sadly, the added macros are written to
+the `idx` files, which break `makeindex`. The option `counters*` attempts
+to remove the conflicting macros in the following way:
+* `pdftex` and `xetex` pre-expand `\thepage` just before it’s written by
+  the output routine, so that the expanded string doesn’t include them.
+  This means the modified `\thepage` is written to the `aux` file, too.
+* `luatex` processes the string to be written with a callback, only when
+  `\indexentry` is present.
+## Fixes
+* With 'select.write = omit' the main language wasn’t selected
+  in the aux file.
+* Incorrect link box in end of line if it is preceded by a non-Arabic
+  character (#207). Note that, very often, directions in labels and the
+  like must be overriden, because the bidi algorithm knows nothing
+  about the ‘semantics’ of text. This can be done with `\mbox` and
+  `\babelsublr`.
