+API: Contract Constraints
+=========================
 
 A basic understanding of contract key concepts, which can be found :doc:`here </key-concepts-contracts>`,
 is required reading for this page.
 
 Transaction states specify a constraint over the contract that will be used to verify it.  For a transaction to be

-not sufficient to specify the verify() function by name as there may exist multiple different implementations with the

 This mechanism exists both for integrity and security reasons. It is important not to verify against the wrong contract,
 which could happen if the wrong version of the contract is attached. More importantly when resolving transaction chains

+Before reading this page, you should be familiar with the :doc:`key concepts of Corda <key-concepts>`.
+
+Internal APIs and stability guarantees
+--------------------------------------
+
+.. warning:: For Corda 1.0 we do not currently provide a stable wire protocol or support for database upgrades.
+   Additionally, the JSON format produced by the client-jackson module may change in future.
+   Therefore, you should not expect to be able to migrate persisted data from 1.0 to future versions.
+
+   Additionally, it may be necessary to recompile applications against future versions of the API until we begin offering
+   ABI stability as well. We plan to do this soon after the release of Corda 1.0.
+
+   Finally, please note that the 1.0 release has not yet been security audited. You should not run it in situations
+   where security is required.
+
+Corda artifacts can be required from Java 9 Jigsaw modules.
+From within a ``module-info.java``, you can reference one of the modules e.g., ``requires net.corda.core;``.
+
+.. warning:: while Corda artifacts can be required from ``module-info.java`` files, they are still not proper Jigsaw modules,
+   because they rely on the automatic module mechanism and declare no module descriptors themselves. We plan to integrate Jigsaw more thoroughly in the future.
+
+Corda stable modules
+--------------------
+
+The following modules have a stable API we commit not to break in following releases, unless an incompatible change is required for security reasons:
+
+* **Core (net.corda.core)**: core Corda libraries such as crypto functions, types for Corda's building blocks: states, contracts, transactions, attachments, etc. and some interfaces for nodes and protocols
+* **Client RPC (net.corda.client.rpc)**: client RPC
+* **Client Jackson (net.corda.client.jackson)**: JSON support for client applications
+
+Corda incubating modules
+------------------------
+
+The following modules don't yet have a completely stable API, but we will do our best to minimise disruption to
+developers using them until we are able to graduate them into the public API:
+
+* **net.corda.node.driver**: test utilities to run nodes programmatically
+* **net.corda.confidential.identities**: experimental support for confidential identities on the ledger
+* **net.corda.node.test.utils**: generic test utilities
+* **net.corda.finance**: a range of elementary contracts (and associated schemas) and protocols, such as abstract fungible assets, cash, obligation and commercial paper
+* **net.corda.client.jfx**: support for Java FX UI
+* **net.corda.client.mock**: client mock utilities
+* **Cordformation**: Gradle integration plugins
+
+Corda unstable modules
+----------------------
+
+The following modules are available but we do not commit to their stability or continuation in any sense:
+
+* **net.corda.buildSrc**: necessary gradle plugins to build Corda
+* **net.corda.node**: core code of the Corda node (eg: node driver, node services, messaging, persistence)
+* **net.corda.node.api**: data structures shared between the node and the client module, e.g. types sent via RPC
+* **net.corda.samples.network.visualiser**: a network visualiser that uses a simulation to visualise the interaction and messages between nodes on the Corda network
+* **net.corda.samples.demos.attachment**: demonstrates sending a transaction with an attachment from one to node to another, and the receiving node accessing the attachment
+* **net.corda.samples.demos.bankofcorda**: simulates the role of an asset issuing authority (eg. central bank for cash)
+* **net.corda.samples.demos.irs**: demonstrates an Interest Rate Swap agreement between two banks
+* **net.corda.samples.demos.notary**: a simple demonstration of a node getting multiple transactions notarised by a distributed (Raft or BFT SMaRt) notary
+* **net.corda.samples.demos.simmvaluation**: A demo of SIMM valuation and agreement on a distributed ledger
+* **net.corda.samples.demos.trader**: demonstrates four nodes, a notary, an issuer of cash (Bank of Corda), and two parties trading with each other, exchanging cash for a commercial paper
+* **net.corda.node.smoke.test.utils**: test utilities for smoke testing
+* **net.corda.node.test.common**: common test functionality
+* **net.corda.tools.demobench**: a GUI tool that allows to run Corda nodes locally for demonstrations
+* **net.corda.tools.explorer**: a GUI front-end for Corda
+* **net.corda.tools.graphs**: utilities to infer project dependencies
+* **net.corda.tools.loadtest**: Corda load tests
+* **net.corda.verifier**: allows out-of-node transaction verification, allowing verification to scale horizontally
+* **net.corda.webserver**: is a servlet container for CorDapps that export HTTP endpoints. This server is an RPC client of the node
+* **net.corda.sandbox-creator**: sandbox utilities
+* **net.corda.quasar.hook**: agent to hook into Quasar and provide types exclusion lists
+
+.. warning:: Code inside any package in the ``net.corda`` namespace which contains ``.internal`` or in ``net.corda.node`` for internal use only.
+   Future releases will reject any CorDapps that use types from these packages.
+
+.. warning:: The web server module will be removed in future. You should call Corda nodes through RPC from your web server of choice e.g., Spring Boot, Vertx, Undertow.
+
+The ``@DoNotImplement`` annotation
+----------------------------------
+
+Certain interfaces and abstract classes within the Corda API have been annotated
+as ``@DoNotImplement``. While we undertake not to remove or modify any of these classes' existing
+functionality, the annotation is a warning that we may need to extend them in future versions of Corda.
+Cordapp developers should therefore just use these classes "as is", and *not* attempt to extend or implement any of them themselves.

+This annotation is inherited by subclasses and subinterfaces.
