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

2019-12-01    Split off 0.19 branch from master
2020-01-03    Release 0.19.0 final (aim)

                pblocktree.reset();
                pblocktree.reset(new CBlockTreeDB(nBlockTreeDBCache, false, fReset));
                if (fReset) {
                    pblocktree->WriteReindexing(true);

                if (ShutdownRequested()) break;
                
                
                
                
                if (!LoadBlockIndex(chainparams)) {
                    if (ShutdownRequested()) break;
                    strLoadError = _("Error loading block database").translated;
                    break;
                }
                
                
                if (!::BlockIndex().empty() &&
                        !LookupBlockIndex(chainparams.GetConsensus().hashGenesisBlock)) {
                    return InitError(_("Incorrect or no genesis block found. Wrong datadir for network?").translated);
                }
