Please upgrade testnet validators to the latest commit in testnet branch (`5380e6f`).
This update makes backward-incompatible change to block.tlb: ConfigParam 43, in particular size_limits_config_v2#02 constructor. Note, however, that this constructor was never used in both testnet/mainnet yet.

Please upgrade testnet validators to the latest commit in testnet branch (e985ac0).

Also please update Mytonctrl to commit 7e90e26 via command:

update master

If previously you used mytonctrl2 branch, this command will switch back to master: mytonctrl2 is now merged to master. For MTC on master branch it will just update mtc.

In case of any issues check updated documentation and contact us.

Upd: mtc commit changed from 47275a9 to 7e90e26

It is also expedient to update MTC to latest commit of master: e85a541

Note, that this upgrade introduce changes to account storage in block.tlb:
In particular StorageUsed and StorageInfo are changed from

storage_used$_ cells:(VarUInteger 7) bits:(VarUInteger 7) 
  public_cells:(VarUInteger 7) = StorageUsed;
storage_info$_ used:StorageUsed last_paid:uint32 due_payment:(Maybe Grams) = StorageInfo;

to

storage_used$_ cells:(VarUInteger 7) bits:(VarUInteger 7) = StorageUsed;
storage_extra_none$000 = StorageExtraInfo;
storage_extra_info$001 dict_hash:uint256 = StorageExtraInfo;
storage_info$_ used:StorageUsed storage_extra:StorageExtraInfo last_paid:uint32
              due_payment:(Maybe Grams) = StorageInfo;

Previously public_cells were always zero thus old data is parseable under new rules, however once storage_extra_info will be activated new data won't be parsed by old indexers and parsers. It is expected that new scheme will be activated in testnet in early May and in mainnet in June. Please be prepared.
