-Release 2.0.0
-=============
-
-* A new class `RDF::Changeset` has been added. This is meant to replace any
-  previous use of `RDF::Transaction`, which in fact used to in RDF.rb 1.x
-  represent more of a buffered changeset than a genuine transaction scope.
-
-  - Instead of `RDF::Transaction.execute`, use `RDF::Changeset.apply`.
-  - Instead of `RDF::Transaction#execute`, use `RDF::Changeset#apply`.
-
-* The `RDF::Transaction` class has been substantially revamped, including
-  some minor backwards-incompatible changes. These changes will mostly
-  affect repository implementors, not so much general RDF.rb users.
-
-  The changes reflect the expanded purpose of the class: instead of being a
-  mere buffered changeset (for which, see `RDF::Changeset`), transactions
-  are now intended to provide a proper ACID scope for repository queries and
-  mutations.
-
-  We always now also carefully distinguish between read-only and read/write
-  transactions, in order to enable repository implementations to take out the
-  appropriate locks for concurrency control. Note as well that transactions
-  are now read-only by default; mutability must be explicitly requested on
-  construction in order to obtain a read/write transaction.
-
-  In case repository implementations should be unable to provide actual ACID
-  guarantees for transactions, that must be clearly indicated in their
-  documentation. Similarly, implementations should throw an exception when
-  appropriate in case they don't provide write transaction support.
-
-  - `RDF::Transaction#initialize` now takes the target repository as its
-    first argument. Transactions are now always tied to a specific
-    repository instance, instead of being free-floating objects as they used
-    to be (for that, see `RDF::Changeset`).
-
-  - `RDF::Transaction` now mixes in `RDF::Queryable` and `RDF::Enumerable`,
-    enabling quad-pattern matches and BGP queries to execute in a proper
-    transaction scope.
-
-  - The `RDF::Transaction#context` accessor, and its aliases, have been
-    removed. Transactions aren't necessarily scoped to a single graph only.
-
-  - There is a new `RDF::Transaction#repository` accessor for retrieving the
-    target repository object that the transaction operates upon.
-
-  - There is a new `RDF::Transaction#buffered?` predicate for testing
-    whether the changeset that constitutes a transaction is available for
-    introspection. Particular repository implementations may support both
-    options and permit the user the choice on transaction construction.
-
-  - The `RDF::Transaction#inserts` and `#deletes` methods are deprecated.
-    Instead, there is a new `RDF::Transaction#changes` accessor to retrieve
-    an `RDF::Changeset` instance, which contains corresponding methods.
-    For unbuffered transactions, `#changes` returns `nil`.
-
-* Enumerables vs. Enumerators
-
-  - `RDF::Queryable#query` and `RDF::Query#execute` did not return an enumerable, which may be an enumerator. Most internal uses return an Array now, which aides performance for small result sets, but potentially causes problems for large result sets. Implementations may still return an Enumerator, and Enumerators may be passed as arguments.
-  - `RDF::Enumerable#statements`, `#quads`, `#triples`, `#subjects`, `#predicates`, `#objects`, and `#contexts` now return an array rather than an Enumerator.
