upcoming
- faster intersections (and) in some cases thanks to @gssiyankai
version 0.4.9
- Moved select method in the right interface
- Fixed possible bug due to arrayOffset
- Fixed potential issue with trim() on array container
- Added Flyweight iterators to minimize stress on garbage collector when iterating over many long bitmaps (Borislav Ivanov)
version 0.4.8
- Fixed poor hash functions
- Abstraction of common functions across packages
version 0.4.7
- Fixed silly bug in ImmutableRoaringBitmap.xor
version 0.4.6
- Optimized binary search for some common insertion cases
- Reverse iterators
version 0.4.5
- Fixed rare cast of iterator overflow (sethp-jive)
version 0.4.4
- Implemented Rank and Select functions
- Implemented limit
version 0.4.3 (October 25th, 2014)
- Fixed rarely occuring bugs having to do with serialization.
version 0.4.2 (October 24th, 2014)
- Removing unnecessary and buggy toImmutableRoaringBitmap method. Users of previous versions of the library should not use this method.
version 0.4.1 (October 20th, 2014)
- Semantics of the ImmutableRoaringBitmap modified: the input ByteBuffeer is sliced and thus unchanged
version 0.4.0 (September 23rd, 2014)
- Format change to reduce Java RAM memory usage
version 0.3.7 (August 12th, 2014)
- Roaring classes are no longer final
- Added a few convenience methods for fast aggregation using Iterator inputs
version 0.3.6 (June 13th, 2014)
- We can now serialize ImmutableRoaringBitmap.
- Memory usage of ImmutableRoaringBitmap was reduced.
version 0.3.5 (June 12th, 2014)
- Added clone method to iterators
version 0.3.4 (May 23rd, 2014)
- Fixed bug in horizontal_or
version 0.3.3 (May 23rd, 2014)
- Given ImmutableRoaringBitmap an isEmpty method.
- optimized horizontal_or
version 0.3.2 (May 21st, 2014)
- Enabled and fixed iterators.
version 0.3.1 (May 21st, 2014)
- Minor correction to JavaDocs
version 0.3.0 (May 20th, 2014)
- Significant redesign of the classes in the org.roaringbitmap.buffer to reduce heap memory usage
- Some classes were renamed: MappeableRoaringBitmap is now MutableRoaringBitmap
version 0.2.2 (May 14th, 2014)
- fixed typo in documentation
version 0.2.1 (May 13th, 2014)
- adding "isEmpty" methods
- improved AND aggregate between many bitmaps
- implemented horizontal (memory conscious) XOR and OR aggregates between many bitmaps
version 0.2.0 (May 7th, 2014)
- renamed classes in the buffer package to avoid clashes
- fixed a hashCode bug (Dave Hardcastle)
version 0.1.5 (May 1st, 2014)
- improved documentation
version 0.1.4 (April 28st, 2014)
- fixed serialization bug (Björn Sperber)
version 0.1.3 (April 21st, 2014)
- minor cleaning (Rory Graves)
version 0.1.2 (April 15th, 2014)
- serialization format should not be the same for both org.roaringbitmap.RoaringBitmap
and org.roaringbitmap.buffer.RoaringBitmap
- Performance of org.roaringbitmap.buffer.RoaringBitmap should not be on par with
org.roaringbitmap.RoaringBitmap when the buffer is backed by an array
version 0.1.1 (March 28th, 2014)
- made serialized format slightly more concise:
added the serialize/deserialize methods throughout
to bypass Java serialization overhead
- added the serializedSizeInBytes() method for users who
wish to query the memory usage
version 0.1.0 (March 21th, 2014)
- Another fix for serialization
- Introduction of the org.bitmap.buffer package for memory-mapped bitmaps
version 0.0.2 (March 12th, 2014)
- Serialization fix (Jon Alvarado)
version 0.0.1 (March 3rd, 2014)
- First public release
