[Agda] [ANNOUNCE] Agda 2.5.2 release candidate 1

[Sergei Meshveliani]

I have tested  Agda-2.5.1.2.20161216

on  docon-A-0.04,  ghc-7.10.2, MAlonzo 

by type-checking, compiling, and running several test/demo programs. 

The results are correct. 
It shows the same performance (in type checking, compilation, running)
as Development Agda of October 4.  

For future
----------
Concerning developing an algebraic library, the main problem remains: 
the type check performance (by space*time).

There is known a simple example with folding a certain binary operation,
which shows exponential explosion for the type check cost.
And  --sharing  fixes this explosion.

Still  --sharing  does not improve the cost of type-checking docon-A
(it make the cost greater).

It looks like there is something related to deeply nested records
representing generic algebraic structures. 
I tried to make this depth smaller by reorganizing the architecture.
But this is a messy work, and I doubt about how much will this
complicate the program, and also whether this will reduce the type check
cost. 

Regards,

------
Sergei
