Here is a proposed release schedule for 0.19.0, the next major release of Bitcoin Core. Like for previous major releases I've aimed for a release 6 months after the last ( #14438).

2019-09-01 :heavy_check_mark: 
---------------
- Open Transifex translations for 0.19
- Soft translation string freeze (no large or unnecessary string changes until release)
- Finalize and close translations for 0.17

2019-09-15 :heavy_check_mark: 
---------------
- Feature freeze (bug fixes only until release)
- Translation string freeze (no more source language changes until release)

2019-10-01 :heavy_check_mark: 
---------------
- Split off `0.19` branch from `master`
- Start RC cycle, tag and release `0.19.0rc1`
- Start merging for 0.20 on master branch

2019-11-03 :heavy_check_mark:
---------------
- Release 0.19.0 final (aim)

If any specific dates or timeframes are a problem for you, let me know.

**Edit:** schedule was moved two months back on 2019-05-07, for reference, the old schedule was:
```
2019-11-01    Soft translation string freeze
2019-11-15    Feature freeze
2019-12-01    Split off 0.19 branch from master
2020-01-03    Release 0.19.0 final (aim)
```

    GetMainSignals().RegisterWithMempoolSignals(mempool);
    
    
    
    
    g_wallet_init_interface.Construct(interfaces);
    /* Register RPC commands regardless of -server setting so they will be
     * available in the GUI RPC console even if external calls are disabled.
     */
    RegisterAllCoreRPCCommands(tableRPC);
    for (const auto& client : interfaces.chain_clients) {
        client->registerRpcs();
    }
    g_rpc_interfaces = &interfaces;
#if ENABLE_ZMQ
    RegisterZMQRPCCommands(tableRPC);
#endif
    /* Start the RPC server already.  It will be started in "warmup" mode
     * and not really process calls already (but it will signify connections
     * that the server is there and will be ready later).  Warmup mode will
     * be disabled when initialisation is finished.

    if (gArgs.GetBoolArg("-server", false))
    {
        uiInterface.InitMessage_connect(SetRPCWarmupStatus);
        if (!AppInitServers())
            return InitError(_("Unable to start HTTP server. See debug log for details.").translated);
    }
