https://release.debian.org/migration/testing.pl?package=tarantool:

Trying to update tarantool from 1.6.3.539.g211672f-1 to
1.6.7.551.ga5bafc5-1 (candidate is 25 days old):

+ tarantool/amd64 unsatisfiable Depends: binutils (<< 2.25.90.20151126)
+ missing build on XXX: tarantool-common (from 1.6.3.539.g211672f-1)

* use fiber_wakeup() in fiber_yield_timeout()
  to make sure we don't fiber_call() a fiber which
  is perhaps already in cord->ready list.
* don't use diag_create() in fiber_new() if the fiber is
  recycled, this may leak a leftover exception in the
  diagnostics area
* replace rlist_del(&fiber->state) with an assert,
  and fix the places in which a ready fiber can
  be called without first having been removed from the
  ready list.

Fixed small submodule and attached

Now OutOfMemory exception is used everywhere, ER_MEMORY_ISSUE is left only for error code

* clear diag in fibers, avoid leaks, reused fibers start with clean diag
* the following policy is now enforced: the active fiber must be removed
    from cord->ready, to prevent spurious wakeups due to fiber_wakeup-s in
    the past
* reset fiber->f when fiber is awaiting to be reused in fiber loop,
    instant crash if woken by mistake

Move xdir_scan() outside recover_remaining_wals().
In recovery_follow_f, the function invoked in local hot standby
mode or remote recovery, only invoke xdir_scan() if we're at the
end of the current log (or have no log file at all).

I've checked that packages actually work on Fedora Rawhide (systemd) and
CentOS 6 (sysvinit). It should be safe to switch our builds to the new
spec and remove old one after fixing problems with tarantool/build [2][3].
