0.9.3 - 2026-09-12

Changed

• No package-specific changes were recorded; solana_kit_codecs_data_structures was updated to 0.9.3 as part of group main.

0.9.2 - 2026-09-06

🐛 Fixed

Bound array decoding from untrusted bytes

Reject missing, invalid, and excessive array counts, and stop remainder decoders that fail to consume input. Callers can set a smaller maxItems limit for application-specific formats.

0.9.1 - 2026-08-30

Changed

• No package-specific changes were recorded; solana_kit_codecs_data_structures was updated to 0.9.1 as part of group main.

0.9.0 - 2026-08-30

🚀 Feature

Typed tuple codecs and explicit integer factories

Add typed getTuple2Encoder/getTuple2Decoder helpers to solana_kit_codecs_data_structures, exposing two-element tuples as Dart records. Give the integer codec factories in solana_kit_codecs_numbers explicit generic specializations while preserving their existing FixedSizeEncoder<num> public return types. codama-renderers-dart now emits getTuple2* for arity-2 tuple nodes, escapes Dart reserved-word identifiers, keeps generated instructionData locals collision-free, and gives generated byte/list fields recursive value equality and hashing.

📖 Documentation

Unslop package docs and code comments

Rewrote every package README from a reader's perspective with verified, compilable examples, removed AI-tell phrasing from docs and code comments, and added a test that analyzes every Dart block in Markdown so examples cannot drift from the API.

0.8.0 - 2026-08-19

🐛 Fixed

Reject non-canonical boolean decoder values

Boolean codecs now reject values other than zero and one with a typed error, including nullable prefixes that use boolean tags.

💥 Breaking Change

@solana/kit v7.0.0 upstream sync (foundational breaking changes)

Ports the foundational breaking changes from @solana/kit v7.0.0:

• solana_kit_errors: new transactionIntrospection error domain + codes (transactionFailedToDecompileInstructionAccountIndexOutOfRange, transactionIntrospectionCannotDecodeJsonParsedTransaction, transactionIntrospectionUnrecognizedGetTransactionResponse) and instruction-plans max-instructions codes (instructionPlansInvalidMaxInstructionsPerTransaction, instructionPlansMaxInstructionsPerTransactionExceeded).
• solana_kit_codecs_data_structures: createDependentStructDecoder fluent builder for structs whose later fields depend on earlier decoded values.
• solana_kit_instruction_plans: configurable maxInstructionsPerTransaction (default 16, limit 64) on TransactionPlannerConfig, individual TransactionPlanner invocations, and MessagePacker; invocation-specific planner values take precedence without leaking to later calls.
• solana_kit_rpc_types: isSolanaRpcResponse runtime guard.
• solana_kit: removed the local getMinimumBalanceForRentExemption helper (rent exemption is becoming dynamic; use the RPC method instead).
• solana_kit_subscribable: ReactiveStreamStore v7 rewrite — caller-driven connect()/reset()/withSignal(), starts idle, collapses retrying into loading (stale-while-revalidate), renames getUnifiedState() → getState(); removed retry(), value-only getState(), getError(). ReactiveActionStore now passes a fresh CancellationToken to every action, cancels superseded/reset/disposed dispatches, suppresses late outcomes, exposes caller cancellation through withSignal(), and preserves stale results and errors while running.
• solana_kit_transaction_introspection: new first-class package porting @solana/transaction-introspection — RPC transaction decoding, instruction and inner-instruction extraction, loaded-address resolution, and instruction walking helpers; re-exported from the solana_kit umbrella.
• solana_kit_rpc_parsed_types / solana_kit_rpc_transformers / solana_kit_rpc_api: Agave 4.1.0 parsed-account types — vote commissions/latency as int (not BigInt); rent sysvar union (lamportsPerByte vs deprecated burnPercent/exemptionThreshold/ lamportsPerByteYear); stake warmupCooldownRate optional; config slashPenalty/warmupCooldownRate deprecated; keep vote commissions and latency as int in the numeric-keypath allow-lists.

Migration: getMinimumBalanceForRentExemption(space) → rpc.getMinimumBalanceForRentExemption(space).send(); store.retry() → store.connect(); store.getUnifiedState() → store.getState(); the deprecated ReactiveStore/createReactiveStoreFromStreams → createReactiveStreamStore; reactive actions must migrate from (args) async => result to (signal, args) async => result.

// Before
final lamports = getMinimumBalanceForRentExemption(space);
store.retry();
final state = store.getUnifiedState();

// After
final lamports = await rpc.getMinimumBalanceForRentExemption(space).send();
store.connect();
final state = store.getState();

0.6.0 - 2026-08-12

📖 Documentation

Centralize package version documentation

Centralize package version metadata in versions.json and render package installation snippets from the shared MDT data source. Published package behavior is unchanged.

Owner: @ifiokjr · Review: PR #188

Point package README website badges at package docs

Updated package README website badges to link directly to each package's docs catalog entry and added missing package entries to the documentation website catalog/index.

0.5.0 - 2026-06-01

💥 Breaking Change

Raise minimum Dart SDK to 3.12

Raise the minimum supported Dart SDK constraint to ^3.12.0 across public Dart packages.

This is a breaking change because consumers must use Dart 3.12 or newer. Flutter consumers must use a Flutter SDK that bundles Dart 3.12 or newer.

environment:
  sdk: ^3.12.0

🧪 Testing

Improve test coverage to 95%+ across all packages

Added 500+ tests covering equality/hashCode/toString, codec edge cases, error paths, and constructor variants. Removed dead code in fast_stable_stringify. Fixed concurrent modification bug in subscribable.

0.4.0 - 2026-05-30

📝 Changed

Restructure release groups

Move program-specific and domain-specific packages out of the main release group into standalone release schedules with independent versioning. Core SDK packages remain synchronized in the main group.

Owner: Ifiok Jr. · Introduced in: fccec7f · Last updated in: 93b3cd3

🐛 Fixed

Add per-package coverage badges

Add codecov flags and per-package coverage badges to all package READMEs.
