Plan for GHC 9.2

[Simon Peyton Jones]

Ben

Can we get record dot syntax into 9.2?

* Shayne is really nearly there in !4532; he has been working
  hard and recently.
* It depends on my !4981 (was 4722) which fixes some bugs and
  I'm keen to commit.


So, is it ok in principle to pull to trigger on !4981, and hopefully !4532?

|  tl;dr. Provisional release schedule for 9.2 enclosed. Please discuss,
|         especially if you have something you would like merged for
|  9.2.1.
|  
|  Hello all,
|  
|  With GHC 9.0.1 at long-last out the door, it is time that we start
|  turning attention to GHC 9.2. I would like to avoid making the mistake
|  made in the 9.0 series in starting the fork in a state that required a
|  significant amount of backporting to be releaseable. Consequently, I
|  want to make sure that we have a fork schedule that is realistic given
|  the things that need to be merged for 9.2. These include:
|  
|   * Update haddock submodule in `master` (Ben)
|   * Bumping bytestring to 0.11 (#19091, Ben)
|   * Finishing the rework of sized integer primops (#19026, John
|  Ericson)
|   * Merge of ghc-exactprint into GHC? (Alan Zimmerman, Henry)
|   * Merge BoxedRep (#17526, Ben)
|   * ARM NCG backend and further stabilize Apple ARM support? (Moritz)
|   * Some form of coercion zapping (Ben, Simon, Richard)
|   * Tag inference analysis and tag check elision (Andreas)
|  
|  If you see something that you would like to see in 9.2.1 please do
|  holler. Otherwise, if you see your name in this list it would be great
|  if you could let me know when you think your project may be in a
|  mergeable state.
|  
|  Ideally we would strive for a schedule like the following:
|  
|      4 February 2021:   We are here
|         ~4 weeks pass
|      3 March 2021:      Release branch forked
|         1 week passes
|      10 March 2021:     Alpha 1 released
|         3 weeks pass
|      31 March 2021:     Alpha 2 released
|         2 weeks pass
|      14 April 2021:     Alpha 3 released
|         2 weeks pass
|      28 April 2021:     Alpha 4 released
|         1 week passes
|      5 May 2021:        Beta 1 released
|         1 week passes
|      12 May 2021:       Release candidate 1 released
|         2 weeks pass
|      26 May 2021:       Final release
|  
|  This provides ample time for stabilization while avoiding deviation
|  from the usual May release timeframe. However, this would require that
|  we move aggressively to start getting the tree into shape since the
|  fork would be less than four weeks away. I would appreciate
|  contributors'
|  thoughts on the viability of this timeline.
|  
|  Cheers,
|
