• An Intel or AMD x86 processor with two or more cores, at 1.6GHz or faster (2GHz or faster for a stake pool or relay)
• Or, for MacOS, an Apple Silicon processor
• 24GB of RAM when running with the InMemory backend, 8GB when running with the OnDisk backend (pending confirmation)
• 300GB of free storage (350GB recommended for future growth)

• Linux 64-bit (Ubuntu 20.04 LTS, 22.04 LTS, 24.04 LTS, 26.04 LTS; Mint 20, 21, 21.1, 21.2, 21.3, 22, 22.1, 22.2; Debian 11, 12, 13)
• Windows 64-bit (10, 11)
• MacOS 10.15, 11 (Big Sur), 12 (Monterey), 13 (Ventura), 14 (Sonoma), 15 (Sequoia), 26 (Tahoe)

• GHC 9.6
• Cabal 3.8/3.12

• Pre-release configuration files
• Docker Images: cardano-node, cardano-tracer, cardano-submit-api

• 🟢 - signed / agreed / supported
• 🟥 - not agreed / unsupported

• Bulk credentials handling was fixed (#6502)

• Support for TLS encrypted HTTPS connections to endpoints. To use that, the config needs to provide a "tlsCertificate": {} object and set the optional field "epForceSSL": true on individual has* endpoints. For a detailed example, see cardano-tracer's Changelog.
• Experimental: New (optional) hasTimeseries endpoint. By configuring this, cardano-tracer will maintain an internal timeseries store for all connected Nodes' metrics. The store can be queried via the /timeseries/query path, POSTing the query as plain UTF8 text. Query examples can be found in folder bench/cardano-timeseries-io/examples; the query language is heavily inspired by PromQL.

• Significantly improve mempool performance: transaction differences are cached the first time the transaction is validated, and re-used when revalidating the mempool on forging and syncing with the LedgerDB.
• Fix directory management in LSM-trees snapshot conversion.
• Ignore exceptions when deleting a snapshot.

• Added ScriptContextBuilder test utility (PlutusLedgerApi.Test.ScriptContextBuilder) to plutus-ledger-api-testlib for constructing realistic ScriptContext values in tests using a composable builder pattern.
• Improved the performance and testing of the flat library.
• Improved the performance of writeBits.
• Improved the uplc executable: it now supports taking contract blueprints as input (#7685), and configuring optimization options (#7682).

• Exposed some PrometheusSimple backend DoS protection parameters in the Node config (see example below). All of those fields are optional and will selectively override the hard-coded default.
• The ChainDB.AddBlockEvent.SwitchedToAFork trace message now contains a "reason" field stating why a chain fork was chosen. Example messages in #6014 .
• New rpc.request.* metrics denoting the timespan for evaluating gRPC methods.
• Performance optimizations for evaluation of some metrics.

Example:

    "TracePrometheusSimpleRun": {
		"connCountGlobal": 20,
		"connCountPerHost": 8,
		"connPerSecond": 10.0,
		"connTimeout": 30
    }
