 Package: release-notes 
 Severity: wishlist 
  
 During the trixie cycle, the tzdata package reduced the set of timezone 
 files that it ships, moving many of them to tzdata-legacy on the basis 
 that the upstream tz project considers them to be for backward 
 compatibility: 
  
 tzdata (2023c-8) unstable; urgency=medium 
  
   [...] 
   * Ship only timezones in tzdata that follow the current rules of 
 geographical 
     region (continent or ocean) and city name. Move all legacy timezone 
 symlinks 
     (that are upgraded during package update) to tzdata-legacy. This 
 includes 
     dropping the special handling for US/* timezones. (Closes: #1040997)

 People ran into this at the time (#1051973, #1056908), and the response 
 was to add a NEWS.Debian entry: 
  
 tzdata (2023d-1) unstable; urgency=medium 
  
     From 2023c-8 on the tzdata package ships only timezones that follow the 
     current rules of geographical region (continent or ocean) and city name. 
     All legacy timezone symlinks (old or merged timezones mentioned in the 
     upstream backward file) were moved to tzdata-legacy. This includes the 
     US/* timezones. 
  
     Please install tzdata-legacy in case you need the legacy timezones or to 
     restore the previous behavior. This might be needed in case the system 
     provides timezone-aware data over the network (e. g. SQL databases).

 That's fine as far as it goes, but 
 https://rachelbythebay.com/w/2025/09/11/debtz/ points out that it would 
 be a good idea to mention this in the release notes.  I agree: it's the 
 sort of thing that can cause weird symptoms in various packages after 
 the upgrade, and if you didn't carefully read through all the 
 NEWS.Debian entries at the time then you might not think to look in 
 tzdata for (say) a PostgreSQL problem. 
  
 Thanks,
