+# DNS Seed Testing Tool
+
+A standalone utility to test DNS seed servers for the Rincoin network.
+
+## Overview
+
+This tool queries DNS seed servers using the same methods as the Rincoin Core client, making it ideal for:
+- Testing your own DNS seeder implementation
+- Verifying DNS seed configuration
+- Debugging connectivity issues
+- Monitoring DNS seed health
+
+## Building
+
+### Quick Build
+
+```bash
+./build-test-dns-seeds.sh
+```
+
+### Building with Rincoin Core
+
+If you're building the full Rincoin Core:
+
+```bash
+./autogen.sh
+./configure
+make
+# The tool will be built as: src/test-dns-seeds
+```
+
+### Manual Build
+
+If you need to build manually:
+
+```bash
+g++ -std=c++17 -O2 -Wall -Wextra -I. -Isrc \
+    src/test-dns-seeds.cpp \
+    src/netbase.cpp \
+    src/netaddress.cpp \
+    src/chainparams.cpp \
+    [... other required source files ...] \
+    -lpthread -lboost_system -lboost_filesystem -lboost_thread \
+    -o test-dns-seeds
+```
+
+## Usage
+
+### Basic Usage
+
+Test all configured mainnet DNS seeds:
+```bash
+./test-dns-seeds
+```
+
+Test testnet seeds:
+```bash
+./test-dns-seeds -testnet
+```
+
+### Advanced Options
+
+```
+Usage: test-dns-seeds [options]
+
+Options:
+  -testnet              Test testnet seeds instead of mainnet
+  -regtest              Test regtest seeds instead of mainnet
+  -maxips=<n>           Maximum number of IPs to request from each seed (default: 256)
+  -seed=<hostname>      Test only a specific seed (can be used multiple times)
+  -servicebits=<hex>    Query for specific service bits (default: 0x0)
+  -timeout=<n>          Connection timeout in seconds (default: 5)
+  -verbose              Show detailed output
+  -help                 Display help message
+```
+
+### Examples
+
+Test a specific DNS seed:
+```bash
+./test-dns-seeds -seed=seed.rincoin.net
+```
+
+Test with specific service bits (e.g., NODE_NETWORK = 0x1):
+```bash
+./test-dns-seeds -servicebits=1
+```
+
+Get verbose output showing all returned IP addresses:
+```bash
+./test-dns-seeds -verbose
+```
+
+Test multiple specific seeds:
+```bash
+./test-dns-seeds -seed=seed1.rincoin.net -seed=seed2.rincoin.net
+```
+
+Limit the number of IPs requested:
+```bash
+./test-dns-seeds -maxips=50
+```
+
+## Output
+
+The tool provides:
+- Status of each DNS seed query (success/failure)
+- Number of addresses returned by each seed
+- Sample of returned IP addresses (first and last 5)
+- Summary statistics:
+  - Total seeds tested
+  - Success rate
+  - Total addresses returned
+  - Average addresses per seed
+
+### Exit Codes
+
+- `0`: All tests passed successfully
+- `1`: All DNS seed queries failed
+- `2`: Some DNS seed queries failed
+
+### Example Output
+
+```

+
+✓ All DNS seeds are working correctly!
+```
+
+## How It Works
+
+The tool mimics the DNS seed resolution logic from Rincoin Core's `ThreadDNSAddressSeed()` function:
+
+1. Reads DNS seed hostnames from chainparams (just like the Core client)
+2. Optionally prepends service bit filter (e.g., `x1.seed.rincoin.net`)
+3. Performs DNS lookup using `LookupHost()` (same function as Core)
+4. Displays all returned IP addresses
+5. Provides success/failure statistics
+
+## Testing Your DNS Seeder
+
+When developing a DNS seeder, use this tool to verify:
+
+1. **Basic Connectivity**: Can the seed hostname be resolved?
+   ```bash
+   ./test-dns-seeds -seed=your-seed.example.com
+   ```
+
+2. **Service Bit Filtering**: Does your seeder support service bit queries?
+   ```bash
+   ./test-dns-seeds -seed=your-seed.example.com -servicebits=1
+   ```
+
+3. **Response Size**: Are you returning an appropriate number of addresses?
+   ```bash
+   ./test-dns-seeds -seed=your-seed.example.com -verbose
+   ```
+
+4. **Network-Specific Seeds**: Test each network separately
+   ```bash
+   ./test-dns-seeds -seed=your-seed.example.com  # mainnet
+   ./test-dns-seeds -seed=your-seed.example.com -testnet
+   ```
+
+## Troubleshooting
+
+### "DNS lookup failed"
+- Check that the hostname is correct and resolvable
+- Verify your DNS server is accessible
+- Try with `-verbose` for more details
+
+### "Seed responded but returned no addresses"
+- Your seeder is online but has no peers to return
+- Check your seeder's peer database
+- Verify your seeder is actually crawling the network
+
+### Build errors
+- Ensure you have built Rincoin Core first (`./configure && make`)
+- Check that all dependencies are installed
+- Try the quick build script: `./build-test-dns-seeds.sh`
+
+## Integration with CI/CD
+
+You can integrate this tool into your CI/CD pipeline:
+
+```bash
+#!/bin/bash
+# Check DNS seeds health
+./test-dns-seeds -timeout=10
+if [ $? -ne 0 ]; then
+    echo "DNS seed check failed!"
+    exit 1
+fi
+```

+<#
+.SYNOPSIS
+    LOCAL, TESTING-ONLY build of Rincoin Core Windows (x64) binaries, on Windows,
+    using Docker + the MinGW-w64 cross toolchain.
+
+.DESCRIPTION
+    Requires only Docker Desktop (no WSL distro and no local compiler needed).
+
+    >>> These binaries are for LOCAL TESTING / VERIFICATION ONLY.           <<<
+    >>> They are UNSIGNED and NOT reproducible. Do NOT publish them or use  <<<
+    >>> them for official releases — use the project's release process for  <<<
+    >>> that (contrib/build_release.sh in a clean, reproducible env).       <<<
+
+    Everything expensive is cached and reused between runs:
+      * the MinGW dependency build (depends/) and the compiled objects live
+        in a Docker named volume, so the slow first build (~30-60 min) is a
+        one-time cost; later builds are incremental and fast;
+      * ccache is persisted in its own volume.
+
+    Nothing is added to the git repo: output goes to release-builds-local/
+    (git-ignored) and all caches are Docker volumes outside the tree.
+
+.PARAMETER Clean
+    Remove the cached build/deps/ccache volumes and previous output, then
+    rebuild from scratch.
+

+<#
+.SYNOPSIS
+    Run the CI ASan/UBSan build + tests LOCALLY in Docker, reproducing the
+    GitHub Actions "asan+ubsan" leg so you can iterate without commit/push/wait.
+
+.DESCRIPTION
+    Mirrors ci/test/00_setup_env_native_asan.sh exactly: ubuntu:20.04, clang,
+    system libraries (NO_DEPENDS), CPPFLAGS='-DARENA_DEBUG -DDEBUG_LOCKORDER',
+    --with-sanitizers=address,integer,undefined, and the same ASAN/UBSAN/LSAN
+    runtime options + in-tree suppression files. If it passes here it should
+    pass the asan+ubsan CI leg.
+
+    Requires only Docker Desktop. The build tree, object files and ccache live
+    in Docker named volumes, so the first run is slow (~15-25 min) and later
+    runs are incremental and fast. Nothing is written into the repo or git.
+
+.PARAMETER Suite
+    Run only one Boost unit-test suite from the main test binary (fast path),
+    e.g. -Suite scriptpubkeyman_tests. Builds incrementally, then runs just
+    that suite. Omit to run the full 'make check'.
+
+.PARAMETER Check
+    Force a full 'make check' (all unit tests, incl. libmw) even if -Suite is
+    given. This is the default when -Suite is not specified.
+
+.PARAMETER Jobs
+    Parallel build/test jobs. Defaults to the container's CPU count.
+
+.PARAMETER Clean
+    Remove the cached build + ccache volumes, then rebuild from scratch.
+
+.EXAMPLE
+    contrib\test-asan-local.ps1 -Suite scriptpubkeyman_tests   # fast iterate
+    contrib\test-asan-local.ps1                                 # full make check

-Notable changes
-===============
+## Unreleased — current development
 
-Important Security Updates
---------------------------
+No consensus rules change in this line; it is maintenance and infrastructure
+work only. Highlights so far:
 
-This release contains fixes for the following security vulnerabilities:
+- **Reverted the v1.1.0-rc1 RinHash "activations table."** The JSON-driven,
+  code-generated consensus table has been removed. RinHash Argon2d parameters
+  are hard-coded again (`t=2, m=64, lanes=1, salt="RinCoinSalt"`); the PoW
+  output is unchanged. The per-network peer-protocol-version floor is retained
+  as plain `Consensus::Params` constants (see
+  [`doc/rincoin-parameters.md`](rincoin-parameters.md) §5).
+- **Small correctness fixes:** add missing `<stdexcept>` include; use
+  `CHECK_NONFATAL` instead of `assert` for the MWEB HogEx `vout` invariant so a
+  construction-time violation cannot abort the node.
+- **Network identity:** the internal IPv6 prefix is now derived from
+  `SHA256("rincoin")` (`FD 2D DD 82 F5 C8`) instead of the inherited
+  Litecoin-derived value, with matching `net`/`netbase` test vectors.
+- **Continuous integration:** a GitHub Actions workflow runs the upstream
+  container-based CI harness with two legs — a plain unit+functional build and
+  an ASan/UBSan build. The gate is headless (core unit tests + functional
+  suite); Qt GUI test vectors are a separate follow-up. Each run publishes a
+  downloadable `test-results-<leg>` artifact.
+- **Test suite made green:** rebranded the `bitcoin-util` test fixtures to
+  `rincoin-tx` with Rincoin addresses, dropped the stale Litecoin smoke
+  benchmark from `make check`, and added UBSan suppressions for the intentional
+  wrapping arithmetic in the crypto primitives.
+- **Fixed a signed-integer overflow in the MWEB fee calculation** (`CFeeRate`):
+  `mweb_weight * BASE_MWEB_FEE` now saturates instead of overflowing on
+  pathological weights. Caught by UBSan; the result is unchanged for any valid
+  transaction (real MWEB weights are far below the saturation bound).
+- **Fixed a missing `cs_main` lock in `CChainState::InitCoinsDB`.** The MWEB
+  coins-view initialization reads the best block and coins DB, which require
+  `cs_main`; the lock was not taken, so `DEBUG_LOCKORDER` (sanitizer) builds
+  aborted during test setup. Behavior is unchanged in release builds.
+- **Further sanitizer fixes:** held `cs_wallet` in the MWEB stealth-address
+  unit test (matching production callers, so `DEBUG_LOCKORDER` no longer
+  aborts), and suppressed the intentional wrapping in Boost's `hash_combine`
+  used by libmw aggregation.
+- **Local build helpers (developer tooling, not shipped):**
+  `contrib/build-windows-local.ps1` (Docker + MinGW cross-build on Windows) and
+  `contrib/build-linux-local.sh` (native, ccache-accelerated), plus
+  `contrib/test-asan-local.ps1` / `.sh`, which reproduce the CI ASan/UBSan leg
+  in Docker (with a fast single-suite mode) so sanitizer issues can be caught
+  locally without commit/push. All are for local testing only and keep their
+  outputs and caches out of the repository.
+- **Docs:** added [`doc/rincoin-parameters.md`](rincoin-parameters.md) and this
+  consolidated history.

+## v1.0.5 — unit-test correctness & sync
+
+- Fixed all unit tests that still referenced Litecoin (LTC) constants so they
+  use Rincoin (RIN) parameters throughout.
+- Header-synchronization optimization for faster initial headers download.
+- DNS-seed logging improvements.
+
+## v1.0.4 — maintenance
+
+- Fixed MWEB file operations failing on Windows with non-ASCII data paths.
+- DNS-seed updates and additional seeders.
+- Qt: shift+click range selection in the coin-control dialog.
+- Updated checkpoints and build tooling; assorted build fixes.
+
+## v1.0.2 / v1.0.3 — RinHash v2 (rolled back)
+
+These releases introduced **RinHash v2**. It was **not adopted by the network**
+and was subsequently **rolled back**; the RinHash v1 proof-of-work remains in
+force. These versions are listed here only for historical completeness.
+
+## v1.0.1 — maintenance
+
+- Version bump and minor fixes over v1.0.0 (icons, chainparams touch-ups,
+  max-supply information).
+
+## v1.0.0 (= Litecoin v0.21.4) — Rincoin base
+
+The initial Rincoin Core baseline, forked from Litecoin `v0.21.4`, introducing
+the RinHash proof-of-work and Rincoin network identity. It carried the upstream
+security backports present in Litecoin `v0.21.4`, including:
+
+- **CVE-2024-35202** — remote DoS via `blocktxn` message handling (backported
+  from Bitcoin Core).
+- **Mutated-blocks propagation** fix (backported from Bitcoin Core).
+- **miniupnp** infinite-loop / OOM fix (backported).
+- Default `-peerblockfilters`/`-blockfilterindex` to off when pruning is
+  enabled, plus functional-test fixes.

+# Rincoin Network & Consensus Parameters (Test Reference)
+
+This document is the single, authoritative reference for the Rincoin-specific
+constants that the code and the test suites depend on. It exists for
+**transparency**: every value below is either taken directly from
+`src/chainparams.cpp` or derived from first principles (a documented formula or
+the genesis block), so that maintainers, auditors, and external users can
+verify it **independently** rather than trusting a test to compare a value with
+itself.
+
+> When a test hard-codes a Rincoin-specific value (a genesis hash, an address
+> prefix, the internal IPv6 prefix, …), the expected value must be the one
+> documented here and derivable from the chain or a stated formula — not simply
+> whatever the current build happens to output.
+
+Source of truth: [`src/chainparams.cpp`](../src/chainparams.cpp) is authoritative
+for all network parameters. Values here are for reference and review.
+
+---
+
+## 1. Proof of Work — RinHash
+
+RinHash is the Rincoin PoW function, applied to the 80-byte block header:
+
+```
+SHA3-256( Argon2d( BLAKE3(block_header) ) ) < target
+```
+
+Argon2d parameters (see [`src/crypto/rinhash.cpp`](../src/crypto/rinhash.cpp)):
+
+| Parameter | Value      | Notes                          |
+| --------- | ---------- | ------------------------------ |
+| `t_cost`  | `2`        | iterations                     |
+| `m_cost`  | `64`       | memory, in KiB                 |
+| `lanes`   | `1`        | parallelism                    |
+| `salt`    | `RinCoinSalt` | ASCII                       |
+
+Canonical PoW test vector: see `rinhash_canonical_pow_vector` in
+[`src/test/rinhash_tests.cpp`](../src/test/rinhash_tests.cpp).
+
+## 2. Block subsidy & timing
+
+| Parameter                | Value                    |
+| ------------------------ | ------------------------ |
+| Initial block subsidy    | `50 RIN`                 |
+| Halving interval         | `210,000` blocks         |
+| Target block spacing     | `60` seconds             |
+| PoW target timespan      | `33` hours               |
+| Difficulty algorithm     | legacy retarget until block `30,000`, Dark Gravity Wave (DGW) per-block thereafter (mainnet) |
+
+> The mainnet emission schedule is the standard halving-by-`210,000` schedule.
+> No customized-halving consensus change is in force. Any future change to the
+> emission schedule will be documented here and shipped as an explicit,
+> community-reviewed consensus change.
+
+## 3. Per-network parameters
+
+All hashes are big-endian as displayed by `getblockhash`/`getbestblockhash`.

+| Subsidy halving interval      | `210,000` |
+
+### Testnet
+
+| Parameter            | Value |
+| -------------------- | ----- |
+| Genesis block hash   | `00009d5fbc8579e8b4292f1bab22437d9468c0cc615cb5b0242d8159b31760ad` |

+
+## 4. Internal IPv6 prefix (ADDRv1)
+
+Non-IP peers (Tor/I2P/CJDNS/internal) embedded in ADDRv1 use a chain-specific
+6-byte prefix. Rincoin derives it the same way Bitcoin/Litecoin do, from the
+coin name:
+
+```
+INTERNAL_IN_IPV6_PREFIX = 0xFD || SHA256("rincoin")[0:5]
+                        = FD 2D DD 82 F5 C8
+```
+
+Independently verifiable, e.g.:
+
+```sh
+printf 'rincoin' | sha256sum
+# 2ddd82f5c8...  → prefix = FD 2D DD 82 F5 C8
+```
+
+Defined in [`src/netaddress.h`](../src/netaddress.h); exercised by
+`cnetaddr_serialize_v1/v2`, `cnetaddr_unserialize_v2` in
+[`src/test/net_tests.cpp`](../src/test/net_tests.cpp) and
+`netbase_lookupnumeric` in
+[`src/test/netbase_tests.cpp`](../src/test/netbase_tests.cpp).
+
+## 5. Peer-protocol-version floor
+
+A per-network minimum peer protocol version becomes effective at a set height.
+Below the floor, peers are disconnected during the version handshake.
+
+| Network  | Floor height | `min_peer_protocol_version` |
+| -------- | ------------ | --------------------------- |
+| mainnet  | `840,000`    | `70018` |
+| testnet  | `4,200`      | `70018` |
+| regtest  | `600`        | `70018` |
+| preview  | `600`        | `70018` |
+
+Configured as plain constants in `Consensus::Params`
+(`nMinPeerProtoVersionFloorHeight`, `nMinPeerProtoVersionFloor`); see
+`rinhash_peer_proto_floor_params` in
+[`src/test/rinhash_tests.cpp`](../src/test/rinhash_tests.cpp).
+
+---
+
+## How to obtain / re-derive these values
+
+- **Genesis hashes / merkle roots**: start a node on the target network and run
+  `rincoin-cli getblockhash 0` and `getblock <hash>`; or read the `assert(...)`
+  lines in `CMainParams` / `CTestNetParams` / `CRegTestParams` in
+  `src/chainparams.cpp`.
+- **Coinbase txid of genesis** (used by `RPCNestedTests`): for a single-tx
+  block the coinbase txid equals the block's merkle root (mainnet:
+  `8590c085…c47cdad`).

+# Rincoin Core v1.1.0 Release Notes
+
+**Release Date:** *to be set on tag*
+**Base Commit:** `b52c87778` (master / v1.0.5 line)
+**Branch:** `release-v1.1.0-community-maintenance`
+
+---
+
+## Overview
+
+v1.1.0 is a **community-maintenance and infrastructure release**. It does
+not change the consensus rules in force on mainnet today. Instead it lands
+the framework that future RinHash and consensus parameter changes will
+travel through, ships one narrow forward-looking overlay (a peer-protocol-
+version floor at the per-network activation-0 height), and folds in
+operational/tooling improvements that have accumulated since v1.0.5.
+
+Highlights:
+
+- **RinHash activations table** — a single JSON consensus table
+  (`src/consensus/rinhash_consensus.json`) drives a code-generated header,
+  a runtime resolver (`Consensus::Params::GetRinHashEffectiveAt`), and a
+  CI guard (`gen_rinhash_consensus.py --check`) preventing JSON↔code
+  drift. See `doc/rinhash-activations.md`.
+- **Peer-protocol-version floor at activation 0** —
+  `min_peer_protocol_version = 70018` becomes effective at heights
+  `840000` (mainnet, 4th halving), `4200` (testnet), `600` (regtest), and
+  `600` (preview). From those heights onward, v1.1.0 nodes disconnect
+  peers that have not advertised at least `nVersion = 70018` during the
+  version handshake.
+- **`PROTOCOL_VERSION` bump 70017 → 70018** to advertise the activations
+  table handshake.
+- **Previewnet (`preview` chain)** — a fourth chain dedicated to
+  rehearsal, with its own magic, ports, address prefixes, and HRPs but
+  reusing testnet's genesis. Activated via `-preview`.
+- **HogEx empty-vin fix** — `CheckTransactionInputs` and the MWEB miner
+  no longer reject HogEx transactions for having an empty `vin`, the
+  required shape for the MWEB peg-out aggregator transaction.
+- **Splash and logo** restored to the v1.0.1 assets after a regression
+  that landed in the v1.0.4 line.
+
+## Backward Compatibility
+
+v1.1.0 does not change the consensus rules currently in force on mainnet.
+Block validation, PoW, transaction format, subsidy rules, chain selection,
+existing blocks, wallets, and datadirs remain compatible with the v1.0.x
+line. The new peer-protocol floor is scheduled for the activation height
+and affects network reachability, not historical block validity.
+
+---
+
+## Major Changes
+
+### 1. RinHash Activations Table
+
+A small, auditable, JSON-driven framework for height-indexed consensus
+parameter changes.
+
+- **Authoritative table:** `src/consensus/rinhash_consensus.json` —
+  per-network `init` baseline plus an ordered list of `activations[]`
+  overlays.
+- **Schema:** `src/consensus/rinhash_consensus.schema.json` — validated
+  during code generation.
+- **Generator:** `python3 src/consensus/gen_rinhash_consensus.py` produces
+  `src/consensus/rinhash_consensus_data.h`. CI runs it with `--check`;
+  PRs that hand-edit the header without regenerating fail the build.
+- **Build wiring:** `src/Makefile.am` invokes `--check` as part of the
+  default build target.
+- **Runtime resolver:** `Consensus::Params::GetRinHashEffectiveAt(int height)`
+  returns the `RinHashEffective` (Argon2d parameters + the
+  `min_peer_protocol_version` floor) in force at any height.
+- **Last-write-wins per field:** overlays specify only the fields they
+  change; everything else inherits from the most recent prior overlay or
+  the `init` baseline.
+
+See `doc/rinhash-activations.md` for the full design and a worked example
+of adding a new overlay.
+
+### 2. Peer-Protocol-Version Floor at Activation 0
+
+The v1.1.0 activation-0 overlay sets `min_peer_protocol_version = 70018`
+at the per-network activation heights below. From those heights forward,
+peers advertising `nVersion < 70018` are disconnected during the version
+handshake (`net_processing.cpp`, VERSION handler).
+
+| Network  | Activation-0 height | Floor  |
+|----------|---------------------|--------|
+| mainnet  | 840000              | 70018  |
+| testnet  | 4200                | 70018  |
+| regtest  | 600                 | 70018  |
+| preview  | 600                 | 70018  |
+
+Below the activation height the floor is dormant (`0`); the existing
+`MIN_PEER_PROTO_VERSION = 31800` continues to be the only floor enforced.
+
+### 3. `PROTOCOL_VERSION` Bumped to 70018
+
+`src/version.h` advertises `PROTOCOL_VERSION = 70018` to signal support for
+the RinHash activations table. v1.0.x peers (`70017`) remain interoperable
+with v1.1.0 peers everywhere except after activation-0, where they will be
+disconnected during the version handshake.
+
+### 4. Previewnet (`preview` Chain)
+
+A fourth chain dedicated to rehearsal mining and integration drills,
+ported from work originally landed under `customized-halving`:
+
+- `-preview` command-line flag, `[preview]` config section.
+- P2P magic `rinp` (`0x72 0x69 0x6E 0x70`); ports `49555` (P2P),
+  `49556` (RPC).
+- Bech32 HRPs `prin` / `prmweb`; base58 prefixes `56` (PUBKEY),
+  `118` (SCRIPT), `219` (SECRET); ext-key prefixes `0x03E25D80` /
+  `0x03E25946`.
+- Reuses testnet's genesis verbatim — simplifies sync and tooling.
+- Activation-0 overlay matches regtest (height `600`, floor `70018`).
+
+### 5. MWEB HogEx Empty-vin Fix
+
+`src/consensus/tx_check.cpp` now exempts HogEx transactions from the
+"transaction has no inputs" check, and `src/mweb/mweb_miner.cpp` asserts
+the HogEx structural invariant before block assembly so a malformed
+HogEx fails fast rather than producing an invalid block. This restores
+the ability to mine MWEB blocks that contain a HogEx aggregator
+transaction with an empty `vin` (its specified shape).
+
+### 6. Splash and Logo Restored
+
+`src/qt/res/icons/{rincoin.png, rincoin_splash.png, bitcoin.ico,
+bitcoin_testnet.ico}` are restored to their v1.0.1 (`5cf3d4a113`) form,
+reverting an unintended asset change that landed in the v1.0.4 line.
+
+---
+
+## RPC Changes
+
+- **New:** `getrinhashparams` — returns the `effective` RinHash
+  parameters and `min_peer_protocol_version` floor at the current tip,
+  plus a `next_change` block describing the next scheduled overlay (if
+  any).
+- **Extended:** `getblockchaininfo` now contains a top-level `rinhash`
+  object with the same `effective` payload, suitable for explorers and
+  health dashboards.
+
+## P2P Changes
+
+- `PROTOCOL_VERSION = 70018`. The bump is non-disruptive on its own; the
+  associated peer floor is gated on the per-network activation-0 height.
+
+## Testing
+
+- **Unit tests** (`src/test/rinhash_tests.cpp`): canonical PoW vector,
+  init-only dormancy, mainnet/testnet/regtest/preview activation-0
+  boundaries, height-aware `GetPoWHash` overload, pending-salt rejection.
+- **Functional test** (`test/functional/feature_min_peer_proto_floor.py`):
+  regtest end-to-end — pre-activation low-version peer accepted, post-
+  activation low-version peer disconnected, post-activation peer at the
+  floor accepted.
+- **Codegen guard** (`gen_rinhash_consensus.py --check`): wired into the
+  build; fails PRs whose JSON and generated header are out of sync.
+
+---
+
+## Upgrade Procedure
+
+Node operators, miners, and exchange/explorer integrators should plan a
+coordinated upgrade before mainnet block `840000`. From that height
+onward, peers still running v1.0.x will be unable to maintain connections
+to v1.1.0 peers.
+
+- **Wallet users:** standard upgrade — replace binaries, restart.
+  No datadir migration required; no reindex required.
+- **Miners:** upgrade ahead of mainnet height `840000`. After activation,
+  v1.0.x miners will be unable to maintain peer connections.
+- **Pools / explorers / exchanges:** plan a window before mainnet height
+  `840000`; consume `getrinhashparams` if you wish to surface the
+  upcoming change to users.
+
+## Known Issues
+
+- Customised halving, alternative Argon2d parameter sets, and any new
+  transaction-level consensus rules are explicitly out of scope for
+  v1.1.0 and remain subjects for separate, community-reviewed proposals.
+

+Thanks to everyone who contributed to this release, including the
+upstream Litecoin and Bitcoin Core developers whose work this builds on.
