What

A ## Compatibility section in the README, after Installation:

• The node releases the SDK is tested against: supra_node_v11.7.2 (Mainnet and Testnet) and
  supra_node_v12.0.0.rc7 (Devnet). These are the releases the three networks' public RPC nodes run today. The SDK
  calls /rpc/v3 only.
• A table of the methods and parameters that need a v12 node, with what a v11.7.2 node does instead:
  account_history / iter_account_history, the settlement value of transaction_type, the release field of
  version(), and sequence_number=0 for a sponsored sender without an account. Each row comes from the method's
  docstring on master.
• Pointers to the existing README sections and docstrings for the other differences: where an account holds SUPRA,
  how a feed ends, and the error for a missing account.

The section names no SDK version; the 0.2.0 release PR adds it.

Test run behind the statement

On master e795c09, unchanged, against fresh localnets of each release (chain ID 255):

	supra_node_v12.0.0.rc7	supra_node_v11.7.2
make test-unit with SUPRA_RPC_URL (node-backed tests included)	397 run, 0 failed, 0 skipped	397 run, 0 failed, 0 skipped
make examples (all 14)	passed (see below)	passed
examples/fungible_asset.py	migration step skipped (SUPRA already in the primary store)	migration step ran, then transfer and account_fa_transactions

On rc7 the first make examples run exited with a failure in your_coin, whose traceback was not captured. The rc7
node's error log is empty and its access log has no unexpected status. Two further full runs (all 14; and 13 with
EXAMPLES_EXCLUDE=faucet from a funded key) and your_coin on its own passed.

Checks

make fmt-check, make lint, make typecheck, make test-unit (397 tests, OK, 26 node-backed skipped),
make test-spec (248 scenarios), make build: pass.
