GeoGig 1.0-RC4 Release Notes

December 19, 2016.
These are the release notes for the fourth GeoGig release candidate.
Five important things happended since 1.0-RC3 besides several bug fixes:

  • First and foremost, the developer's team got three new memebers. Join us
    to congratulate (and thank!) David Blasby, Morgan Thompson, and Alex Goudine
    for becoming geogig committers and help us drive this project further and farther.
  • We have cleared out all of our Intellectual Property checks on all our
    dependencies and have now LocationTech blessing to perform
    a sponsored release!
    Thanks to LocationTech, Eclipse Foundation's geospatial branch for their
    continued support and commitment to the success of this and the other projects
    under it's umbrella.
  • The new RevTreeBuilder infrastructure became mainstream. It replaces the
    legacy tree builder in order to generate revision trees faster, create no
    garbage in the objects database (the old one left dangling tree objects
    increasing the database size unnecessarily), and perhaps more importantly,
    enables the use of the same infrastructure to build spatial and attribute
    indexes on revision graphs (yes, you'll be able to index all your data
    history, stay tunned).
  • The PosgreSQL storage backend is now WAL and replication safe, by moving
    to use B-Tree indexes instead of Hash indexes. Thanks David Blasby for the
    thorough performance testing.
  • The default storage backend for local repositories now uses Rocksdb.
    It's faster than the old BerkeleyDB Java Edition database, and produces
    smaller databases on disk.
    The BerkeleyDB storage backend was taken off the official build, but Boundless
    still provides a separate plugin download, so if you have existing repositories
    just download the bdbje plugin and unzip it
    under your <geogig installation directory>/lib/ folder.
    We are really really close to a first 1.0 official release now! Maybe even for Christmas!
