The README advertised mainnet, testnet and regtest without saying that
only the CLI can use the test networks, which also ship without bootstrap
servers or checkpoints.
With proof of work skipped, chaining headers from a checkpoint up to a
transaction's block proves nothing: a server can fabricate a header and
fake headers after a real checkpoint. The header must now hash-chain up to
the nearest checkpoint at or above its height, whose hash is hardcoded.
This also anchors heights below the first checkpoint. The cached anchor
state is renamed AnchoredDownTo and caches without it are re-verified
once. Blocks above the newest checkpoint remain a documented limit.
See ADR 0040.
After connecting, the Send tab offers Fast/Normal/Economy rates from the
server's fee estimates (never below the relay fee, implausible values
ignored). A manual rate below the relay fee is refused before building and
a fee above 1% of the amount is flagged in the preview. See ADR 0039.
The password no longer has to be a command-line argument: it can come from
--password-env, --password-stdin or a no-echo prompt (--password still works
but warns). Plaintext storage is now an explicit opt-in (--no-encryption)
instead of the result of a forgotten flag. See ADR 0038.
Adding a contact now checks the address against the wallet's network and
rejects duplicates; whitespace in a pasted address is removed. Before, any
string was stored and the error only surfaced at send time.
Address rows and the address detail sheet no longer carry the WIF of
every listed address for the whole session. The key is derived after the
password gate and dropped when hidden, when the sheet closes or when the
wallet closes. See ADR 0037.
After the handshake the wallet checks server.features genesis_hash and,
when the profile has checkpoints, the header at the highest checkpoint
not above the server's tip (mainnet shares Bitcoin's genesis, so the
checkpoint is what tells the chains apart). A server on another chain is
refused with WrongChainException and the next candidate is tried. Used by
the GUI, peer discovery, the CLI and the server probe. See ADR 0036.
A hostile server could stream an endless line with no newline and exhaust
the client's memory. A single reply is now capped at 16 MiB (configurable
via maxLineBytes in ConnectAsync); on excess the connection fails with
InvalidDataException. See ADR 0035.
A server that stops answering without closing the socket left a running
sync waiting forever. Requests now fail with TimeoutException after 30 s
(10 s for the handshake, both configurable in ConnectAsync) and the
connection is marked dead so the app reconnects. See ADR 0034.
On Italian/German systems "1.5" was read as 15 sat/vB. The Send form,
the Donate form and the CLI now share CoinAmount.TryParseFeeRate
(invariant culture, '.' or ',' as decimal separator, range (0, 1000]).
Donate and the CLI report an invalid rate instead of silently using 1.
Fills in the CHANGELOG.md entry for the watch-only address-only import
mode, progressive Merkle verification, transaction size-limit fix, and
Android sync-reconnect fixes since 1.0.0, and bumps <Version>/versionCode
across the App and Android head csproj files ahead of the tag.
Fills in the CHANGELOG.md entry for the checkpoint-anchoring security fix,
fuzzing infrastructure and its findings, OP_RETURN/coinbase-tag decoding,
and localization fixes since 0.9.1 (see previous commits), and bumps
<Version>/versionCode across the App and Android head csproj files ahead
of the tag.
Fills in the CHANGELOG.md entry for the test-suite expansion and bug fixes
since 0.9.0 (see previous commits), and bumps <Version>/versionCode across
the App and Android head csproj files ahead of the tag.
Technical changelog covering the full history from the initial commit,
grouped by subsystem (Core/Chain, Crypto, Net, Spv, Storage, Wallet, App UI,
Android, CLI, Build, Testing, Docs) rather than raw commit order, since this
is the first release.
