Bug Fixes

• #1314 Fix a bug in Subscriber's Future impl.

Improvements

• documentation improved

Improvements

• #1164 widen some trait bounds on trees and batches

New Features

• #1151 Send is implemented for Iter
• #1167 added Tree::first and Tree::last functions
  to retrieve the first or last items in a Tree, unless
  the Tree is empty.

Bug Fixes

• #1159 dropping a Db instance will no-longer
  prematurely shut-down the background flusher
  thread.
• #1168 fixed an issue that was causing panics during
  recovery in 32-bit code.
• #1170 when encountering corrupted storage data,
  the recovery process will panic less often.

New Features

• #1146 added TransactionalTree::generate_id

Improvements

• #1133 transactions and writebatch performance has been
  significantly improved by removing a bottleneck in
  the atomic batch stability tracking code.

New Features

• #1136 Added the TransactionalTree::flush method to
  flush the underlying database after the transaction
  commits and before the transaction returns.

Improvements

• #1132 implemented Fromsled::Error for io::Error to
  reduce friction in some situations.

Breaking Changes

• #1131 transactions performed on Trees from different
  Dbs will now safely fail.
• #1131 transactions may now only be performed on tuples
  of up to 14 elements. For higher numbers, please use
  slices.

Breaking Changes

• #1125 the backtrace crate has been made optional, which
  cuts several seconds off compilation time, but may cause
  breakage if you interacted with the backtrace field
  of corruption-related errors.

Bug Fixes

• #1128 Tree::pop_min and Tree::pop_max had a bug where
  they were not atomic.

New Features

• #1116 IVec::subslice has been added to facilitate
  creating zero-copy subsliced IVecs that are backed
  by the same data.

Bug Fixes

• #1120 Fixed a use-after-free caused by missing ref keyword
  on a Copy type in a pattern match in IVec::as_mut.
• #1108 conversions from Box<[u8]> to IVec are fixed.
