Release Notes

Operator settings applied to the chaincode container are catalogued in Chaincode Environment Variables.

2026-09-01: substrate v2.236.0

• substrate: A context migration can no longer invoke another registered migration — the nested call now raises at the migration's entry point and names both migrations. Previously the rule was only documented, and a nested migration that hit cache silently made the outer fresh step look cached, so a transaction ran more steps than max_fresh_steps_per_tx allowed
• substrate: New nested-migration lint check in shirotester lint and the editor extension moves the same failure to authoring time — it flags a migration body that reaches run-ctx-migrations, run-migration-to-completion or the ctx-migrations registry, directly or through a helper in the same file. It is structural, so it runs identically with --semantic=false and no workspace; the runtime guard remains the complete check
• substrate: Bump ELPS to v1.58.0 — adds the with-cleanup special operator: (with-cleanup (cleanup...) body...) always runs the cleanup forms, whether the body returned normally or signalled, and returns the last body value without catching the error. shirotester lint gains the matching with-cleanup-forms check (a cleanup list that is empty or a bare symbol releases nothing), and load-scope-context now sees inside with-cleanup, which it previously skipped entirely
• substrate: Bump ELPS to v1.59.0 — the shadowing lint no longer reports a binding whose initialiser narrows the name it shadows, such as (let* ([ctx (default ctx (sorted-map))]), and its severity now follows what is hidden: shadowing a builtin, special operator, macro or function is a warning, shadowing another local stays informational
• substrate: Bump ELPS to v1.60.0 — elpspath gains parse-path, which converts a v1 string selector into the positional steps the v2 ? family takes, so a path that arrives as data (a client request, a persisted envelope) is parsed once rather than on every call: (apply ? (cons obj (parse-path sel))). Open-ended slices gain a positional spelling, '(range n) for [n:]. The selector parser is a new single-pass scanner, 67–90% faster on selector strings with fewer allocations and the same grammar and error messages; substrate's own copy of the v1 parser is retired in favour of it. The one grammar change is a strict widening: .["a"]["b"], which the old parser rejected, now parses

2026-08-27: substrate v2.235.0

• substrate: ⚠️ Action may be required for phyla that use the testing package outside test files. Production environments no longer load the testing package, so a phylum whose production load graph reaches it at load scope now fails to load with unknown package: testing. Three shapes trigger it: a top-level (use-package 'testing), a top-level (test ...) / (test-let ...) registration, and a top-level qualified reference such as (testing:assert-equal ...). The common, safe shape is unaffected — a defun whose body calls assert-equal still loads, because symbols in a function body resolve when it is called. The remedy is to move the offending file into the phylum's test-loaded set (a *_test.lisp file), which the test harness loads and production does not
• substrate: The failure is not always loud, which is the part worth checking for. Inside handler-bind or ignore-errors the load succeeds and silently skips the rest of the recovered body — no error, just missing behavior. shirotester preheat-check is the reliable detector: run it against your phylum directory or the deployment ZIP before upgrading
• substrate: Operators who need more time can set SUBSTRATE_ALLOW_PHYLUM_TESTING_PACKAGE=true on the chaincode container to restore the previous behavior while the phylum is migrated. It must be set uniformly across a channel's peers — with it off the affected phylum fails to load and with it on the phylum runs, so peers that disagree disagree about whether the phylum exists at all. Set it the same way wherever shirotester preheat-check runs, or a phylum can pass the check in CI and still fail to load on the peers; the check prints a NOTE naming the variable when it runs with the hatch on. See Chaincode Environment Variables
• substrate: shirotester preheat-check and the runtime's own template-refusal messages now name a line the phylum author can actually edit. A blocking context read reached through a wrapper or a macro previously reported only the position inside the library it bottomed out in — naming a file the phylum does not own, while the phylum's own line never appeared — and because the report de-duplicates on that position, two distinct blockers could merge into a single entry. Reports now read read-position <- reaching-form, and are unchanged for a read written directly at load scope
• substrate: Bump ELPS to v1.57.0 — native values carry typed construction and access contracts, and native payloads are checked against the runtime they belong to, closing a class of cross-transaction leak through environments served by forking a per-phylum template

2026-08-26: substrate v2.234.0

• substrate: blend-paths now guarantees its write-through contract, pinned by tests: values at blended paths alias the source document (a write through the blend result at a blended path is visible in the source patch), the result is independent of the destination, and an empty path list returns the destination by identity. Restores behavior phyla depended on that regressed with the elpspath copy fix in v2.229.0 — the symptom was fields generated on the blend result (ids, timestamps) silently missing from the persisted patch after an update
• substrate: Leaning on the blend-paths write-through aliasing is deprecated for new code — write generated fields onto the source patch explicitly; the aliasing contract is retained for existing phyla
• substrate: New static vet gate rejects native payloads reaching a preheat template, preventing cross-transaction leaks through template-forked environments

2026-08-26: substrate v2.233.0

• substrate: Preparing a transaction's environment is dramatically cheaper — a warm VM is now produced by forking a per-phylum template snapshot instead of initializing from scratch, and the embedded core library is sealed once and shared by every fork rather than copied per environment. Together with the ELPS bump below, the allocations a single fork costs drop from roughly 37,000 to under 7,000 (−81%), so pools of preheated environments fill faster and hold less memory per VM
• substrate: Bump ELPS to v1.56.0 — array values no longer deep-copy dimensions they built themselves, forking no longer rebuilds per-environment metadata nothing reads, and the vector-building builtins moved onto the copy-free path, cutting two allocations from every constructed vector on the transaction path
• substrate: When a phylum cannot be preheated, the report is now trustworthy — shirotester preheat-check and the runtime's own template-refusal message name the innermost phylum source position of each blocking read rather than an internal frame, repeated reads of one capability no longer crowd distinct ones out of the list, and a report that had to truncate says so instead of silently dropping reads
• substrate: The elpspath v1 string-path builtins (get-path, set-path! and friends) are now marked deprecated in hover documentation and shirotester doc, each pointing at its v2 positional-arg equivalent, with a selector-to-step translation table in the package documentation. v1 continues to work — stored data and request payloads still carry v1 path strings — but new phylum code should use the v2 operations, which are several times faster and support dynamic paths naturally

2026-08-25: substrate v2.232.0

• substrate: Context migrations pack by default again — following operator feedback on v2.230.0, a migration now fits as many fresh steps into each transaction as the storage budgets allow (the behavior before v2.230.0), so operators no longer need to know how many steps fit in order to get efficiently packed transactions. The per-transaction step cap is now the opt-in control: pass shiroclient init --migration-tuning '{"max_fresh_steps_per_tx": N}' (for example 1) when the step rather than the budget should decide transaction chunking, such as tests that observe page boundaries. Cached replays remain free, and frontier resume and the exit-code contract are unchanged
• substrate: With packing as the default, size shiroclient init -l to the expected number of budget-sized transactions (typically small); a run tuned down with max_fresh_steps_per_tx needs -l near the total step count divided by that setting

2026-08-25: substrate v2.231.0

• substrate: Phylum loading is dramatically cheaper — the parse cache now hands every environment the same immutably sealed program instead of deep-copying it, removing ~44 ms, ~37 MiB and ~447,000 allocations from every cache hit, and the embedded core library is parsed once per process instead of once per environment, cutting warm-VM construction time by ~69% and its allocations by ~80%. Together these make pools of preheated environments substantially faster to fill and cheaper to hold
• substrate: New shirotester preheat-check command proves whether a phylum fully preheats — it loads the phylum (directory or deployment ZIP) against a probing transaction context and names the exact file and line of any load-scope context read that would silently stall background preheating
• substrate: New load-scope-context lint check (on by default) catches the same pattern statically — a transaction-context read at phylum load scope, such as reading the clock or ledger state at the top level of a file, is flagged at authoring time in shirotester lint and the editor extension, with the fix pattern named in the diagnostic
• substrate: Bump ELPS to v1.54.0 — adds the per-file load cache the parse-cache improvement above is built on, with sealed programs served safely across environments
• substrate: Operators who run a phylum that mutates its own quoted program literals (a pattern the sealed cache now rejects with modify-literal-error) can set SUBSTRATE_ALLOW_PHYLUM_LITERAL_MUTATION=true on the chaincode container to restore the previous behavior while the phylum is updated; the setting must be uniform across a channel's peers and announces itself in the process log — see Chaincode Environment Variables for the full list of settings available on the chaincode container

2026-08-25: substrate v2.230.0

• substrate: Context migrations now perform one fresh step per transaction by default — the batch size a migration chooses is its unit of work per transaction, making transaction sizing predictable and the batch size observable from the returned context; pack more steps per transaction for a single run with shiroclient init --migration-tuning '{"max_fresh_steps_per_tx": N}', no phylum redeploy needed. Cached replays remain free and do not count against the limit
• substrate: Restarting a context migration now resumes in constant time — the engine records each migration's frontier and jumps straight to it, instead of re-reading the cached step history one entry at a time; long-running migrations no longer get slower to resume the further they have progressed, and a completed migration answers immediately on re-run
• substrate: shiroclient init exit codes now distinguish outcomes: 0 means the migrations completed, 3 means the iteration budget (-l) ran out with work remaining — progress is committed, re-run to continue, and the remaining context is logged as paste-ready JSON for -m — and 1 means a real failure, including a new detection for migrations making no progress between iterations. Size -l to the total step count divided by the steps-per-transaction setting
• substrate: New utils:set-index-prefixes builtin — the official override point for index key prefixes
• substrate: Phylum preheating hardening — each environment initializes from its own copy of the phylum, and abandoned initializations are cancelled instead of running to completion in the background
• substrate: Bump ELPS to v1.53.0 — adopts the sealed-AST series for faster program loading and safer reuse of parsed phylum code across environments

2026-08-21: substrate v2.229.0

• substrate: The per-transaction key and write-byte metrics, previously last-write-wins gauges, are now histograms — substrate_tx_keys_accessed and substrate_tx_bytes_written give true per-endpoint distributions (p95s, threshold alerting via plain bucket queries) instead of whichever transaction finished last; the old gauges substrate_tx_keys / substrate_tx_write_bytes still work but are deprecated
• substrate: New substrate_statedb_ops_total{method,op} and substrate_statedb_bytes_total{method,op} counters expose the per-endpoint statedb breakdown — gets, puts, private-data access, range scans, and range pagination — so an endpoint's read/write/private mix is visible over time
• substrate: Sampled OpenTelemetry Handle spans now carry the full statedb breakdown (statedb.* counts and bytes) plus luther.method, luther.req_id, and luther.tx.dirty — a slow trace shows exactly what the transaction touched in state
• substrate: Breaking for dashboards pinned to specific le values — substrate_tx_sim_dur and shirogateway_tx_dur trimmed from 25 to 14 buckets (same 50ms low end, tail extends to ~15s), roughly halving the per-endpoint series cost of the two duration histograms
• substrate: ELPS phylum profiler spans now export through the server's own tracer rather than the process-global one — concurrent substrate instances (such as in-memory tests) no longer leak spans into each other's trace exporters
• substrate: elpspath hardening — set-path/?set copies no longer share nested containers with the source, and a value that contains itself is refused with a catchable error instead of crashing the chaincode process
• substrate: Bump ELPS to v1.50.0 — brings the tracer plumbing and container-aliasing fixes above into the ELPS runtime, with faster transaction evaluation on top
• substrate: The pvtdata sentinel private-data collection now defaults to "private", with an explicit opt-out for deployments that relied on the previous default
• substrate: Clearer error when chaincode source fails to load — the message now names both failed interpretations (not a zip archive, not loadable lisp) instead of reporting only the zip failure
• substrate: Fix cctime:sleep to declare the same arguments as its implementation
• substrate: The benchmark regression gate is now statistically sound (both arms measured interleaved on the same runner) and a daily scheduled govulncheck run watches for vulnerable dependencies — catching performance and security regressions automatically

2026-08-05: substrate v2.228.1

• substrate: Restore the npm trusted-publishing auth in the release pipeline so the @luthersystems/shirotester npm package publishes again for v2.228.x — no runtime changes over v2.228.0

2026-08-05: substrate v2.228.0

• substrate: Fix duplicate results from statedb union range queries — an unbounded range (end="") in statedb:range-page-union / range-page-bytes-union was misclassified as disjoint from every other range, silently emitting duplicate keys; unbounded ends now count as overlapping and results are deduplicated
• substrate: Context migrations now run under per-transaction budgets (max keys, write bytes, and iterations per transaction, deletes counted) with a resumable pause at the cache frontier — large-dataset migrations no longer risk blowing Fabric transaction limits mid-run
• substrate: statedb:range-page* builtins are now legal in writing transactions — the page size is enforced client-side over a plain range iterator, since Fabric restricts shim-level pagination to read-only transactions
• substrate: New out-of-band migration tuning — pass --migration-tuning '{"batch_size": 2000}' to shiroclient init and read values in phylum via utils:migration-tuning; retune a paused migration between runs without redeploying the phylum or invalidating the migration's idempotency cache
• substrate: Unpaginated range queries now stream keys lazily instead of collecting the whole key range into memory up front — constant memory at any range size, closing an out-of-memory class for full-keyspace scans; paginated range builtins now reject a page size <= 0 with a clear error, and a new range-pagination metric exposes page-fetch behavior to operators
• substrate: The in-memory emulator now serves ranges from a true cursor (no more full-range materialization per page during tests), with mock/real range parity proven by one shared corpus and the full migration lifecycle exercised end-to-end on the sample network on every change

2026-08-04: substrate v2.227.0

• substrate: Bump shiroclient-sdk-go to v0.14.1 with the matching grpc security updates
• substrate: Known-vulnerability scanning (govulncheck) and Go-module Dependabot now run on every change, catching vulnerable-dependency regressions of the above class automatically

2026-06-23: substrate v2.226.0

• substrate: Phylum preheat/init timeout is now configurable (default unchanged at 6s) — set it with the --preheat-timeout chaincode flag, the shiro.WithPreheatTimeout server option, or the shiroclient SDK's mock.WithPreheatTimeout (sdk-go v0.14.0) for in-memory tests. Prevents spurious "phylum init timeout" errors when many environments initialize in parallel under heavy CPU load; the baseline preheater always keeps the built-in default, so a small value can't stall all traffic
• substrate: Add a guide for automated context migrations

2026-05-14: substrate v2.225.2

• substrate: Recovered phylum panics now include a Go stack trace (panic origin): section in the error output, pinpointing the exact line that triggered the panic
• substrate: Fix structured logging on the first request to a freshly preheated phylum — error stacks emitted during preheat-interrupt handling now flow through the configured logger instead of stderr
• substrate: Bump ELPS to v1.48.0 — adds a singleton-mutation guard and the Go panic-stack capture feeding the above

2026-05-06: substrate v2.224.0

• substrate: Per-request debug logging now correctly promotes phylum cc:debugf calls to Info level when a sampled OpenTelemetry parent span is present on the transaction
• substrate: Fix OpenTelemetry trace propagation in in-memory / emulate-CC mode — spans now surface from transactions issued through make mem-up and sandbox-style test flows
• substrate: Refresh OpenTelemetry tracing documentation — covers the sampled-parent requirement, per-binary OTLP endpoint configuration, and the log-volume tradeoff when using per-request debug logging
