Highlights

• CLI token tooling: End-to-end APL token management in arch-cli including minting, accounts, delegation, multisig, and advanced ops with walkthrough docs and a lifecycle demo script (#1240, #1341).
• Resharing V2 + crypto: On-chain resharing transcripts with a new crypto crate for primitives and transcript handling (#1366, #1388).
• Validator refactors: Snapshot verification modularized, new state module replacing monolith, block height consensus improvements (#1400).
• Crate reorganizations: Extracted dkg, websocket; added bitcoin-internal, structs, testing_suite, stakes.

Added

• CLI APL Token commands and docs
  • New subcommands: account, mint, delegation, multisig, operations, helpers, utils.
  • Docs: APL_TOKEN_WALKTHROUGH*.md, TOKEN_LIFECYCLE_README.md.
  • Script: token-lifecycle-demo.sh.
  • PRs: #1240, #1341.
• Resharing and crypto
  • Resharing V2 and on-chain transcripts: #1366, #1388.
  • crypto crate: polynomials, Lagrange, DLEQ, encryption, resharing dealer/types/transcripts.
• Crates/splits
  • New/Extracted: dkg, websocket, bitcoin-internal, structs, testing_suite, stakes.
• SDK
  • Async helpers: request_airdrop, create_and_fund_account_with_faucet (#1316).
  • New helpers for program deployment, UTXO ops; expanded types for input_to_sign/transaction_to_sign and tests.
• Program/runtime
  • Pubkey::new_from_array constructor (#1382).
  • Anchor instruction helper (#1383).
  • EBPF artifacts for APL token and associated token account under ebpf/.
• Network/bootnode
  • Bootnode intercept fetches verifying key on DKG path, distributes with network info (#1347).
  • Event types now include block height (#1399).
• Workflows/CI
  • Nightly releases, beta release guide, CI robustness and caching improvements (#1361, #1360, #1363, #1370, #1364).

Changed

• CLI profiles/config
  • Fix: ARCH_NODE_URL respected; remove localhost fallbacks (#1362).
  • Allow force rebuild of local-validator image (#1398).
  • CI gate to prevent running on outdated branches (#1410).
• Program/runtime
  • Program IDs are Base58-compatible and human-readable (#1415).
  • Major updates in sanitized pipeline, transaction_to_sign, and error surfaces.
  • Loader syscall refactors and structure simplification.
• Validator
  • Snapshot verification split into modules with structure/content/verification tests; improved organization and coverage (#1400).
  • New modular state with block height consensus helpers.
• Database
  • Removed unnecessary whole file reads; improved RocksDB usage and caching (#1441).
• Examples/tests
  • Migrations into e2e-tests/ (e.g., orderbook, pda). Added PoCs: duplicate signed txs, same-lamports.

Fixed

• Offset handling and explicit checks on key update (#1442).
• Transaction pool abort/cleanup correctness (#1284, #1309).
• Multiple example cleanups and consistency fixes (escrow, stake, secp256k1).
• CI stability, error handling, caching (#1370, #1393).

Performance and Observability

• Unified logger moved to common for consistent logging (#1353).
• Nightly build optimizations: skip redundant runs; add debug/verification (#1363, #1364).
• Block execution report included in height response (#1355).

RPC and API Changes

• Rename: getVersion → get_version for consistency (#1378).
• Added RPC to fetch group verifying key (#1374).
• SDK: extended types for input_to_sign, transaction_to_sign, runtime_transaction; new tests.

Breaking Changes

• RPC: getVersion → get_version (update clients and scripts).
• Crate splits/imports: validator::dkg::* → dkg::*; Bitcoin internals → bitcoin-internal::*; websockets → websocket::*; shared runtime structs → structs::*.
• Program IDs: Base58/human-readable update may affect hardcoded IDs (#1415).
• Events and messages: Augmented structures (e.g., block height in events). Update SDK usage accordingly.

Migration Guidance

• Update to latest SDK; recompile programs to align with program type and loader/syscall changes.
• Rename all client calls to get_version.
• Adjust imports for crate reorganizations (dkg, websocket, bitcoin-internal, structs).
• Replace any hardcoded program IDs with updated Base58 values.
• Configure profiles with explicit ARCH_NODE_URL; do not rely on localhost defaults.
• Adopt new CLI token commands; see token walkthroughs and lifecycle script.

Documentation

• New: ARCH_STYLE.md, BETA_RELEASE_GUIDE.md, NIGHTLY_BUILD_GUIDE.md, NIGHTLY_SETUP_QUICKSTART.md, CI_TESTING_STRATEGY.md.
• CLI token guides and a lifecycle demo script included under arch-cli/.
