• split stake in distribution !8051 (merged)
• add stake operation for bakers !8120 (merged)
• do not freeze deposits automatically !8087 (merged)
• add parameter baking_edge staking_over_baking_limit !8744 (merged)
• change denunciation rewards: roll/(baking_edge+1) !8939 (merged)
• turn slashing into percentages !8753 (merged)
• store slashed percentage per baker (associative list: cycle -> percentage) !8828 (merged)
• add parameter max_costaking_baker_count = 5 !8766 (merged)
• remove Set_deposits_limit !8831 (merged)
• add storage: costaking_balance: implicit -> pseudotokens
• add storage: uncostaking_requests: implicit -> (costaking bakers * (tez * cycle) list) list
  • on unstake
    • merge head if same cycle
    • auto-withdraw
  • on withdraw:
    • if element is older than preserved_cycle + slashing_period
      • compute real tez value using aforementioned slashed percentages
• update RPC balance
• change storage: staking_balance: tez (deposits), pseudotokens
• add baker pseudo-operation update_delegate_parameters: #5746 (closed)
• use costaking_limit when computing distribution
• rewards: #5790 (closed)

Behind feature flag:

• freeze rewards !8091 (merged)
• apply staking_over_delegation_edge: #5791 (closed)
• stake for non-bakers
  • check costaking_limit (cap to max)
  • reduce spendable balance
  • increase baker staking_balance
  • allocate pseudotokens
  • update costaking_balance (as specified above)
• unstake
  • decrease baker staking_balance
  • compute pseudotokens
  • decrease costaking_balance
  • add a unstaking request
• withdraw

Bonus:

• remove Drain_delegate, or update it
