* Not backported to 4.2.z.  It's not clear to me what the situation on
  4.2 is.  Also not clear to me what sort of updates would trigger
  this issue; whether it is all *-> into broken releases?  Just 4.2 ->
  broken 4.3?  Broken 4.2 -> any 4.3?  For now I'll just assume that
  4.2 is not affected and * -> broken 4.3 is the only vulnerable case.

* 4.2.z: https://bugzilla.redhat.com/show_bug.cgi?id=1801826 Closed WONTFIX.
         https://bugzilla.redhat.com/show_bug.cgi?id=1810136 s380x NEW
  Not sure if that's "does not affect 4.2.z" or "not important enough
  to fix on 4.2.z".

Also, no need to talk about these in the channel YAML files, since we
aren't tombstoning the releases (we discovered the bug after marking
the releases supported by tagging them into fast channels).

Also block * -> 4.3 for 4.3 before 4.3.5, now that we have the Multus
bug to worry about.  4.2 -> 4.3.1 had been blocked before, although
that block was lifted in c641bbd (channels/fast-4.2: Promote 4.2.18
(and 4.2.18+amd64 to fast-4.3), 2020-02-19, #60).  This isolates the
two 4.3 RCs, but we don't commit to providing updates out of candidate
releases anway.  If we get pushback on that (unlikely now that 4.3 has
been GA for so long), we can add rc -> 4.3.6 update edges or some
such.

* autoscaler and machine-API operator both removed their metrics port
  in 4.2 -> 4.3 [1].  So 4.2 clusters which update to 4.3 < 4.3.5 will
  hit this.

* ingress operator removed its metrics port in 4.1 -> 4.2 [2], so 4.1
  clusters which update to 4.2 < 4.2.21 will hit this.

  Not sure if that's "does not affect 4.2.z" or "not important enough
  to fix on 4.2.z".

* It's not clear to me that this is a regression.  Does this actually
  affect update edges at all?

Also, no need to talk about these in the channel YAML files, since we
aren't tombstoning the releases (we discovered the bug after marking
the releases supported by tagging them into fast channels).

Also block * -> 4.3 for 4.3 before 4.3.5, now that we have the Multus
bug to worry about.  4.2 -> 4.3.1 had been blocked before, although
that block was lifted in c641bbd (channels/fast-4.2: Promote 4.2.18
(and 4.2.18+amd64 to fast-4.3), 2020-02-19, #60).  This isolates the
two 4.3 RCs, but we don't commit to providing updates out of candidate
releases anway.  If we get pushback on that (unlikely now that 4.3 has
been GA for so long), we can add rc -> 4.3.6 update edges or some
such.

  14:ec856fba4d [release-4.3] Bug 1808429: UPSTREAM: 88251: Partially fix incorrect configuration of kubepods.slice unit by kubelet
  16:b3bfb5a8f7 Created by command:

* 4.2.z: https://bugzilla.redhat.com/show_bug.cgi?id=1801826 Closed WONTFIX.
         https://bugzilla.redhat.com/show_bug.cgi?id=1810136 s380x NEW
  Not sure if that's "does not affect 4.2.z" or "not important enough
  to fix on 4.2.z".

* This doesn't seem to be a regression, and doesn't seem to be
  update-specific.  UpgradeBlocker was dropped from the 4.3 bug in
  [3].  So I'm just removing references to this series from
  blocked-edges.

Also, no need to talk about these in the channel YAML files, since we
aren't tombstoning the releases (we discovered the bug after marking
the releases supported by tagging them into fast channels).

Also block * -> 4.3 for 4.3 before 4.3.5, now that we have the Multus
bug to worry about.  4.2 -> 4.3.1 had been blocked before, although
that block was lifted in c641bbd (channels/fast-4.2: Promote 4.2.18
(and 4.2.18+amd64 to fast-4.3), 2020-02-19, #60).  This isolates the
two 4.3 RCs, but we don't commit to providing updates out of candidate
releases anway.  If we get pushback on that (unlikely now that 4.3 has
been GA for so long), we can add rc -> 4.3.6 update edges or some
such.

* autoscaler and machine-API operator both removed their metrics port
  in 4.2 -> 4.3 [1].  So 4.2 clusters which update to 4.3 < 4.3.5 will
  hit this.

* ingress operator removed its metrics port in 4.1 -> 4.2 [2], so 4.1
  clusters which update to 4.2 < 4.2.21 will hit this.

* Not backported to 4.2.z.  It's not clear to me what the situation on
  4.2 is.  Also not clear to me what sort of updates would trigger
  this issue; whether it is all *-> into broken releases?  Just 4.2 ->
  broken 4.3?  Broken 4.2 -> any 4.3?  But we don't need to bottom
  that out, because of the next point.

* The impact is only a minute or so of unreachable workloads, after
  which the issue resolves automatically.  The UpgradeBlocker was
  dropped from the 4.3 bug in [3].  So I'm just removing references to
  this series from blocked-edges.

* Not backported to 4.2.z.  It's not clear to me what the situation on
  4.2 is.  Also not clear to me what sort of updates would trigger
  this issue; whether it is all *-> into broken releases?  Just 4.2 ->
  broken 4.3?  Broken 4.2 -> any 4.3?  But we don't need to bottom
  that out, because of the next point.

* The impact is only a minute or so of unreachable workloads, after
  which the issue resolves automatically.  The UpgradeBlocker was
  dropped from the 4.3 bug in [3].  So I'm just removing references to
  this series from blocked-edges.

  Not sure if that's "does not affect 4.2.z" or "not important enough

* This doesn't seem to be a regression, and doesn't seem to be
  update-specific.  UpgradeBlocker was dropped from the 4.3 bug in
  [4].  So I'm just removing references to this series from
  blocked-edges.

Also, no need to talk about these in the channel YAML files, since we
aren't tombstoning the releases (we discovered the bug after marking
the releases supported by tagging them into fast channels).

Also block * -> 4.3 for 4.3 before 4.3.5, now that we have the Multus
bug to worry about.  4.2 -> 4.3.1 had been blocked before, although
that block was lifted in c641bbd (channels/fast-4.2: Promote 4.2.18
(and 4.2.18+amd64 to fast-4.3), 2020-02-19, #60).  This isolates the
two 4.3 RCs, but we don't commit to providing updates out of candidate
releases anway.  If we get pushback on that (unlikely now that 4.3 has
been GA for so long), we can add rc -> 4.3.6 update edges or some
such.

Block 4.2 -> 4.3 for 4.3 before 4.3.5 because of the port bug.  4.2 ->
4.3.1 had been blocked before, although that block was lifted in
c641bbd (channels/fast-4.2: Promote 4.2.18 (and 4.2.18+amd64 to
fast-4.3), 2020-02-19, #60).  I think 1161d00's broader .* blocks
(which I'm relaxing to 4.2.* blocks) on the earlier 4.3 releases were
because the Multus bug affects all updates.  But since the Multus bug
is no longer a blocker, we can restore 4.3->4.3 edges.
