  1. Release 1.2 2011-05-16
  2. ----------------------
  3. Fixes for larger databases (tested up to one billion 100-byte entries,
  4. i.e., ~100GB).
  5. (1) Place hard limit on number of level-0 files. This fixes errors
  6. of the form "too many open files".
  7. (2) Fixed memtable management. Before the fix, a heavy write burst
  8. could cause unbounded memory usage.
  9. A fix for a logging bug where the reader would incorrectly complain
  10. about corruption.
  11. Allow public access to WriteBatch contents so that users can easily
  12. wrap a DB.
