Highlights
==========

SquashFUSE now multi-threaded
-----------------------------

`ch-run`’s FUSE loop is now multi-threaded, which should improve performance
for SquashFS format images (#1157).

CDI now runs `ldconfig(8)` automatically
----------------------------------------

When a shared library (i.e., `*.so` file) is injected into a container,
`ldconfig(8)` must usually be run inside the container to make it available.
The Container Device Initiative (CDI) standard has no notion of either
injected file types or `ldconfig(8)`, relying on CDI spec file authors to
include a hook program that runs it, something provided only by some vendors.
Previously, `ch-run` interpreted the nVidia version of this hook as the signal
to run `ldconfig(8)`. Now, as an extension to the standard, it runs
`ldconfig(8)` if any injected files end in `.so` with optional version number,
eliminating the need for a hook (#2082).
