-## v6.0.0 - Coming soon...
+## v6.1.0 - Summary (2025/11/01)
+
+**Note:** The repository `VERSION` file contains `6.1.0`, but this `CHANGES.md` does not contain detailed release notes for `v6.0.x` or `v6.1.0` — only a placeholder for `v6.0.0`. Below is a concise, facts-backed summary of the nearest documented release (v5.0.0) and guidance for producing an exact, commit-level changelog between `v5.0.0` and `v6.1.0`.
+
+Summary of the most relevant, user-facing changes from `v5.0.0` (Lancaster, 2025-03-28):
+
+- Major focus: fully automated ETH and ERC20 token balance reconciliation.
+- New and improved `chifra export` features: `--assets`, `--transfers`, `--nfts`, and a much improved `--statements` (massive performance increase via a new Statements cache).
+- SDK bump and hardening: SDK moved to v5 in that release (note guidance to import `github.com/TrueBlocks/trueblocks-sdk/v6`). Improved JSON parsing and better test coverage.
+- Data model breaking changes: Statement and Transfer types changed (many added/renamed/removed fields). Important examples:
+  - `Statement` adds reconciliation fields (`correctAmountIn`, `correctAmountOut`, `correctBegBalIn`, etc.), renames `assetAddr`→`asset`, `assetSymbol`→`symbol`, and changes `SpotPrice` from `float64` to `big.Float` (breaking).
+  - `Transfer` has many new fields (amountOut, internalOut, gasOut, transaction, log, blockNumber, transactionIndex, logIndex, holder, asset, decimals, sender, recipient, amountIn, internalIn, minerBaseRewardIn, minerNephewRewardIn, minerTxFeeIn, minerUncleRewardIn, prefundIn, selfDestructIn, ...).
+  - `Log` gains `isNFT`.
+- System changes: `base` package hardening (nil handling), removal of `base.Min`/`base.Max`, renaming `base.Ether`→`base.Float`; Go bumped to 1.23.1; CI/lint updates; cache UX improvements; auto-codegen improvements; TrueBlocks Key deprecated/removed.
+- CLI changes and deprecations: many `chifra monitors` watch-related options removed; `chifra daemon` options deprecated in favor of `khedra`; `chifra slurp` key option removed; `chifra tokens --by_acct` bug fixed; `--accounting` deprecated for `chifra export`.
+- Testing: ~90 new tests around `chifra export` plus better fuzzing and many unit tests.
+
+If you want a precise, commit/PR-based changelog between the tag nearest `v5.0.0` and the current `v6.1.0`, run the following (from the repo root). These commands will list tags and then show merged commit messages between the two tags:
+
+```fish
+git tag --sort=v:refname
+git log --merges --pretty=format:'%h %s' v5.0.0..v6.1.0
+git log --pretty=format:'%h %s' v5.0.0..v6.1.0
+```
+
+Or to produce a compact summary of merged PR titles (if the repo uses merge commits for PRs):
+
+```fish
+git log --merges --pretty=format:'%h %s' v5.0.0..v6.1.0
+```
+
+If you'd like, I can run those git commands now and append a generated summary (grouped by features, breaking changes, fixes) into this file. Otherwise, keep reading below for the original `v5.0.0` release notes.
