Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Deprecating Safe Haskell, or heavily investing in it?
The most recent real case I remember is https://github.com/haskell/mtl/issues/110, which could ended badly.

Type class subsets
Splitting mtl classes into algebraic and non-algebraic components (url) Factor MonadReader into Ask (algebraic) and Local (non-algebraic) classes Factor MonadWriter into Tell (algebraic) and Listen/Pass (non-algebraic)

[ANN] mtl-2.3.1-rc1
It was the example from the ticket which works fine because there is no restriction that the argument to ContT r is a Monad

Draft mtl-2.3 migration guide
I don't think so, but here is a list of upcoming changes in mtl-3.0.
What are some alternatives?
monad-control - Lift control operations, like exception catching, through monad transformers
parallel - a library for parallel programming
capability - Extensional capabilities and deriving combinators
motor - Type-safe effectful state machines in Haskell
record - Anonymous records
recursion-schemes - Generalized bananas, lenses and barbed wire
eveff - Efficient Haskell effect handlers based on evidence translation.
safe-exceptions - Safe, consistent, and easy exception handling
mtl-unleashed - MonadReader and MonadState without the functional dependencies
machines - Networks of composable stream transducers
control-monad-free - Free monads and monad transformers
