+summary:            Fast, light, robust Ethereum implementation
+description:        |
+  Parity's goal is to be the fastest, lightest, and most secure Ethereum
+  client. We are developing Parity using the sophisticated and cutting-edge
+  Rust programming language. Parity is licensed under the GPLv3, and can be
+  used for all your Ethereum needs.

Thibaut Sardan	7fbcdfeed4	Backports for beta 2.2.5 (#10047 ) * bump beta to 2.2.5 * Fix empty steps (#9939) * Don't send empty step twice or empty step then block. * Perform basic validation of locally sealed blocks. * Don't include empty step twice. * Strict empty steps validation (#10041) * Add two failings tests for strict empty steps. * Implement strict validation of empty steps. * ethcore: enable constantinople on ethereum (#10031) * ethcore: change blockreward to 2e18 for foundation after constantinople * ethcore: delay diff bomb by 2e6 blocks for foundation after constantinople * ethcore: enable eip-{145,1014,1052,1283} for foundation after constantinople * Change test miner max memory to malloc reports. (#10024) * Fix: test corpus_inaccessible panic (#10019) If system uptime is less than the duration in the test, thread will panic due to: 'overflow when subtracting duration from instant'. Changed duration to 20 seconds to make it unlikely the test will fail due to this condition. Since no operations that carry a similar risk of panic occur outside of the tests, it doesn't seem warranted to depend on an external crate to fix this. * Bump crossbeam.
