------------------------------+--------------------
 When a plugin has release confirmations are enabled, we store some
 metadata about each release that is made.

 This metadata is specific to release confirmations, and is not related to
 the 'previous versions' metadata.

 When RC is first enabled, we pull in all previously-known releases into
 the history metadata.

 When a new release is made while RC is active, we add it to that
 metadata.[[BR]]
 If RC is not enabled, we don't add metadata.

 Some plugins have enabled RC, and then had it deactivated, and later have
 re-enabled it. When this happens, the metadata ends up being out-of-sync,
 as we haven't stored any releases into the data while it was disabled, and
 because there was previous data, we haven't filled it generated data.

 For example:

 1. Release 1.0, 1.1, and 1.2
 2. Enable RC. Metadata has 1.0-1.2.
 3. Release 1.3, and 1.4.
 4. Disable RC. Metadata has 1.0~1.4
 5. Release 1.5, and 1.6.
 6. Re-enable Release Confirmation. Metadata still only has 1.0~1.4.
 7. Release 1.7. Metadata now has 1.0~1.4 + 1.7

 This causes some plugin authors to be concerned at step 6, as they're
 afraid that they won't get confirmation notices for the upcoming 1.7
 release.

 This also causes some data issues as now they don't have the 1.5+1.6
 releases showing up in their release history.

 Ideally, we should either:
  - Always add releases made by plugins to metadata, regardless of RC.
  - If RC metadata is present, add metadata upon new known releases.
  - Discard data upon it being disabled, or, when re-enabled fill in any
 releases made while it was deactivated.

 This is slightly complicated by releases from trunk, which RC does not
 support, so the metadata may be incomplete for those "releases". (See
 also, #6380)
