DDlog v0.49.0

[0.49.0] - Oct 4, 2021

New features

• Rust compilation option checked_weights for the code generated by
  DDlog, which will crash DDlog programs at runtime if they overflow the
  weights attached to data values. This may be preferable to generating
  incorrect results.

• Add queryIndex Java API (#1093)

Bug fixes

• Closures that depend on generic types generate invalid Rust (#1072).

FlatBuffers

• Upgrade to FlatBuffers v2.0.0. The previous version of FlatBuffers used in
  DDlog is not compatible with recent OS X releases.

SQL-to-DDlog compiler

• Add support for identity views for input tables in DDlogJooqProvider (#1094)
• Translate vector-type fields properly in DDlogJooqProvider (#1089)
• Expose DDlogJooqProvider DSLContext (#1086)
• Windows and Joins work when columns have alias (#1087)
