## Executive Summary (TL;DR)
Cypress v0.11.0. Source highlight: *Released 09/13/2015*

## Improvements
- Removed special logic for *Angular* which tapped into its digest cycle for queueing commands. This had unpredictable results when there was n `interval` set, and is now superseded by the new queueing system anyway (which is more performant).

## Bug Fixes
- Commands which precede assertions will now look downstream at those assertions and not resolve until their subject's state passes all ssertions. Previously this was **sort of** implemented using *Command Options* and the `eventually` flag, but now this is the default ehavior. *Command Options* only worked on DOM-based subjects, and now the new assertion verification works on everything else (including RL-based commands, etc). What this means is that Cypress can predict what you are requesting an
- Action commands will now insert an artificial delay after resolving to enable modern JavaScript frameworks time to *flush* their run loops. snapshots are delayed until after the action, resulting in more accurate snapshots because JavaScript frameworks would not process these DOM vents until `N` milliseconds after they occurred. This has the unfortunate side effect of *decreasing* performance by about *5-10%* but the and result is that it is much easier to debug and Cypress is less prone to flak
- The algorithm for replaying aliased commands is now much more accurate, handles stale element references better, and will not replay commands which have a side effect (like action commands). The end result is Cypress will now almost always find the desired element by determining the minimum number of re-queries and is not susceptible to stale element references. Additionally using assertions on aliased elements now works (where previously using a *Command Option* on an alias would just be ignore
- `Sinon's` formatting of failed `spy` or `stub` calls is horrendously non-performant and would sometimes choke the CPU for several seconds. his formatting has been completely removed and will be replaced by something less insane later on. At the moment you can still use the built n Cypress debugging (clicking on a command log, etc) to see what the actual values were. Fixes #18.
- Cypress now overrides chai's `match` chainer and provides a specific error message when a non `regex` value is provided. Fixes #58.
