2.0.0

Time for a new major version!

This release contains changes that could break/change the behaviour of some existing locust files (but probably not many).

User ramp up/down and User type selection is now controlled by the master instead of autonomously by the workers

This has allowed us to fix some issues with incorrect/skewed User type selection and undesired stepping of ramp up. The issues were especially visible when running many workers and/or using LoadShape:s. This change also allows redistribution of Users if a worker disconnects during a test. This is a major change internally in Locust so please let us know if you encounter any problems (particularly regarding ramp up pace, User distribution, CPU usage on master, etc)

Other potentially breaking API changes

• Change the default User weight to 1 instead of 10 (the old default made no sense)
• Fire test_start and test_stop events on workers too (previously they were only fired on master/standalone instances)
• Workers now send their version number to master. Master will warn about version differences, and pre 2.0-versions will not be allowed to connect at all (because they would not work anyway)
• Update Flask dependency to 2.0
