Release notes

1.5.8
Bugfix: using multipleStatements in mySql could sometimes cause an error when updates are run right before a select.
Improved performance on limit when relating to other tables.
Using uuid instead of node-uuid
Updated all dependencies but generic-pool to latest. (Generic-pool has some breaking changes in latest. I will update it in next release.)
1.5.7
Bugfix: getById.exclusive and tryGetById.exclusive did not lock if row was cached.
Improved performance on tryGetFirst.
1.5.6
Raw sql filters can accept sql both as string and as function. E.g. var filter = {sql: function() {return 'foo > 1';}}.
1.5.5
Optional locks for getMany, tryGetFirst and tryGetById. Instead of calling getMany(params) just call getMany.exclusive(params). Same syntax goes for tryGetFirst and tryGetById. This will result in SELECT FOR UPDATE.
Bugfix: bulk deletes now accepts raw sql filters too.
