0.11.5

• Ported BTSet to JVM
• BTSet and BTSetIter implement ChunkedSeq
• New benchmark runner

This release brings a significant performance boost for JVM version of DataScript (numbers are in comparison to JS/v8 version):

• queries with single clause, no join: ~5–6 times faster
• queries with joins: ~3–4.5 times faster
• transact: ~3 times faster
• init-db: ~3–4 times faster
• rules: ~3-4 times faster

0.11.4

Experimental support for Clojure on JVM:

• sorted-set instead of BTSet
• polymorphic get lookup in query
• no sorting optimisation for init-db
  Performance numbers so far (raw data):
  • queries with single clause, no join: 30–50% faster
  • queries with joins: ~50% slower
  • transact: ~3.5–4 times faster
  • init-db: ~2–2.5 times slower
  • rules: ~2–5 times faster
  • db equiv: ~5 times slower
  • db hash: ~10 times slower

• Fixed UUID constructor warning under CLJS 0.0-3291 and later

0.11.2

• Support reverse attribute refs in combination with wildcards (issue #80)

0.11.0

• Fixed init_db in js (issue #73)

• [ BREAKING ] DS now requires CLJS 0.0-3196 or later

0.10.0

• New parser for query and rules
• Added a lot of meaningful error messages and validations to query parser
• Support for _ (ignore binding) in :in and fn-clause bindings
• Fixed id allocation bug when nested maps are used for referenced entities (issue #59)
• Fixed squuids omitting leading zeros (issue #60)
• Fixed a bug when cross-referencing components caused infinite loop in Pull API (isuue #58, pull request #61)
• Pull API handles recursion more like Datomic does (issue #62)
• Exposed DB filter API to js (pull request #65)
• Added ICounted, ISequable, IEmptyableCollection to datascript.core/DB
• Force put Datom and DB tag readers to cljs.reader/*tag-table*, do not rely on data_readers.clj

0.9.0

• Lookup refs can be inlined in query :where patterns (issue #53)
• Pull API (issue #37, pull request #51) by David Thomas Hume
• pull form in :find clause

0.8.1

• Support for :db/isComponent (issue #3)
• Support for nested maps in transact! (also fixes #38)
• [ BREAKING ] Custom aggregate fns must be called via special syntax (aggregate keyword): (q '[:find (aggregate ?myfn ?e) :in $ ?myfn ...]). Built-in aggregates work as before: (q '[:find (count ?e) ...]
• Return nil from entity when passed nil eid (issue #47)
