This announcement concerns fixes for problems that were introduced
with Postfix 3.2. Older releases are unaffected.
Fixed in Postfix 3.2 and later:
* Extension propagation was broken with "recipient_delimiter = .".
This change reverts a change that was trying to be too clever.
* The postqueue command would abort with a panic message after it
experienced an output write error while listing the mail queue.
This change restores a write error check that was lost with the
Postfix 3.2 rewrite of the vbuf_print formatter.
* Restored sanity checks for dynamically-specified width and precision
in format strings (%*, %.*, and %*.*). These checks were lost with
the Postfix 3.2 rewrite of the vbuf_print formatter.
