Syntax breaking changes

Temporal properties do not need the = in their declaration.

property = eventually(x > 1)

becomes

property eventually(x > 1)

Multiple columns index

This release includes two changes:

1. Unique index can be set on multiple columns
2. Updates do not fail when no row is affected, this mimics the behavior of sql instead of ORM

Unique Index

This release includes:

• Support for unique index on a single column
• Support count() aggregate on select query
• Use parenthesis for temporal operators instead of ocnfusing token: eventually(), always() and never()
• Support for if do ... else ... end

Deadlock detection

Included in this release:

• fixed a bug when updating twice the same row in a transaction
• handle intermediate read correctly
• deadlock detection: deadlocks stopped the model, now entremets displays the cycle of locks that introduced the deadlock
