At the risk of piling on, I too am having problems with Org Capture
templates that haven't changed in a long time. The sample below used to
function like:

   1. I would call it from org-capture, select the “af” template
   2. I would get prompted for a date from file+datetree+prompt and I would
   select the date
   3. I would get prompted for the week number from the
   ~%^{prompt|%<%Y-W%V>}~ clause. This would default to the current week in
   ISO format (2015-W49). I would change it or not (usually not)
   4. The ISO week entered from that prompt would get substituted into the
   AR_DATE property in multiple places.

The two big differences with release_8.3.2-381-gb7ee96 are

   1. The substitution for %Y and %V does not happen before the prompt in
   step 3; I get a default value of [%<%Y-W%V>]
   2. Even if I manually type the ISO week string (2015-W09) it no longer
   gets substituted into the AR_DATE properties via %\1

I maintain some of my more complex capture templates in standalone files
and reference the file in org-capture-templates

(setq org-capture-templates (quote (
                                    ("a" "Templates for Agile Results")

                                    ("af" "Friday Afternoon Weekly Close /
Reflection"
                                     entry
                                     (file+datetree+prompt
"~/Documents/OrgMaster/org/Agile_Results.org")
                                     (file
"~/.init/emacs/org-capture-templates/friday.reflection.org_template")
                                     :jump-to-captured t :immediate-finish
t))))

The
file "~/.init/emacs/org-capture-templates/friday.reflection.org_template"
contains:

#+begin_example
  ,* Friday Reflection %^{prompt|%<%Y-W%V>}
  :PROPERTIES:
  :AR_DATE:  %\1
  :VISIBILITY: all
  :END:
  %u
  ,** Three Things Going Well
  + %?

  ,** Three Things to Improve

 :Weekly_Win_Review:
  :PROPERTIES:
  :AR_DATE:  %\1
  :VISIBILITY: all
  :END:
  %<[%Y-%m-%d %a %H:%M]>
  - What got in my way? How might I do it differently? Review each of my
target Monday
    Vision Outcomes; What did I get done or did not get done?
