[Unison-hackers] Unison stable version, bugfix release (2.27.157)

[Benjamin Pierce]

A new stable version of Unison has been released, incorporating a  
number of miscellaneous bugfixes from Jerome Vouillon.  The new  
version, 2.27.157, is compatible with the old stable version  
(2.27.57).  Package maintainers are encouraged to switch to the new  
version.

Best,

       Benjamin
