For clarity: the hanging indent filter above inserts `\item` in front of every entry, and requires the definition of a  `references` environment in a template:

~~~
\newenvironment{references} {\list{}{% hanging indent, src/myfilters/addRefEnvItem.hs
    \leftmargin1.5em%
    \itemindent-\leftmargin%
    \itemsep0.5ex%
    \parsep0pt%
    }}
    {\endlist}
~~~

I wonder whether the latex writer itself shouldn’t insert such a `references` environment by default. Hanging indent is required by many styles anyway but could be redefined as necessary.

Even better, pandoc(-citeproc) could parse the CSL `hanging` and `second-field-align` flags, and inject appropriate formatting instructions into the `references` environment.

addItem x = [RawBlock (Format "latex") "\\item", x]

… but it has stopped working after the latest updates. What are the adjustments needed?

The bibliography was never part of a template and still
isn't.  It is inserted directly into the document body.

There are various ways to achieve what you want.  One is
write a simple filter that can run after pandoc-citeproc.
It would intercept a Div with id = references, and
add the needed raw latex commands to the beginning and end
of its contents.
