Added

• Added documentation on config system quirks. (#1224)
• Added nengo.utils.network.activate_direct_mode function to make it easier to activate direct mode in networks where some parts require neurons. (#1111, #1168)

Fixed

• The matrix multiplication example will now work with matrices of any size and uses the product network for clarity. (#1159)
• Fixed instances in which passing a callable class as a function could fail. (#1245)
• Fixed an issue in which probing some attributes would be one timestep faster than other attributes. (#1234, #1245)
• Fixed an issue in which SPA models could not be copied. (#1266, #1271)
• Fixed an issue in which Nengo would crash if other programs had locks on Nengo cache files in Windows. (#1200, #1235)

Changed

• Integer indexing of Nengo objects out of range raises an IndexError now to be consistent with standard Python behaviour. (#1176, #1183)
• Documentation that applies to all Nengo projects has been moved to https://nengo.github.io/. (#1251)
