Hi folks,

A new version erofs-utils 1.3 is available at:
git:// tags/v1.3

It mainly includes the following changes:
   - support new big pcluster feature together with Linux 5.13+;
   - optimize buffer allocation logic (Hu Weiwen);
   - optimize build performance for large directories (Hu Weiwen);
   - add support to override uid / gid (Hu Weiwen);
   - add support to adjust lz4 history window size (Huang Jianan);
   - add a manual for erofsfuse;
   - add support to limit max decompressed extent size;
   - various bugfixes and cleanups;

One notable update is that it now supports EROFS big pcluster [1][2],
which allows compressing variable-sized data into more than 1 fs block
by using fixed-sized output compression [3]. It can be used for some
(sub)-files with specific data access patterns (such as oneshot data
segments which need better compression ratio and thus better sequential

Note that users can write their own per-(sub)files big pcluster
strategies to adjust pclustersize in time according to file type static
analysis or historical tracing data in z_erofs_get_max_pclusterblks().
And default strategies will be developed and built-in laterly in the

btw, I've heard more in-market products shipped with EROFS, for example
OPPO [4] and Coolpad [5] with some public news plus more in-person
contacts from time to time. It's always worth trying and feedback or
contribution is welcomed.
