Chia-blockchain

Added

- This is a bug fix release for 1.1.0. It is not required to upgrade from 1.1.0 if you are not experiencing the specific issue that it addresses. You are required to upgrade from any 1.0.x version before Monday evening PDT to continue farming.

Changed

- Logging now includes year, month, and date. Thanks and apologies for not tipping the hat sooner to alfonsoperez for the PR.

Fixed

- Changes were made in 1.1.0 to make sure that even out of order signage points were found and responded to by as many farmers as possible. That change lead to a situation where the harvester could thrash on the same cached signage point.

Added

- This fork release includes full transaction support for the Chia Blockchain. Transactions are still disabled until 5/3/2021 at 10:00AM PDT. It is hard to overstate how much work and clean up went into this release.
- This is the 1.0 release of Chialisp. Much has been massaged and finalized. We will be putting a focus on updating and expanding the documentation on [chialisp.com](https://chialisp.com) shortly.
- Farmers now compress blocks using code snippets from previous blocks. This saves storage space and allows larger smart coins to have a library of sorts on chain.
- We now support offline signing of coins.
- You can now ask for an offset wallet receive address in the cli. Thanks jespino.
- When adding plots we attempt to detect a duplicate and not load it.

Changed

- We have changed how transactions will unlock from a blockheight to a timestamp. As noted above that timestamp is 5/3/2021 at 10AM PDT.
- We have temporarily disabled the "Delete Plots" button in the Windows GUI as we are still working on debugging upstream issues that are causing it.
- There are various optimizations in node and wallet to increase sync speed and lower work to stay in sync. We expect to add additional significant performance improvements in the next release also.
- Transactions now add the agg_sig_me of the genesis block for chain compatibility reasons.
- Wallet is far less chatty to unload the classic introducers. DNS introducers will be coming shortly to replace the classic introducers that are still deployed.
- Netspace is now calculated across the previous 4068 blocks (generally the past 24 hours) in the GUI and cli.

Fixed

- Performance of streamable has been increased, which should help the full node use less CPU - especially when syncing.
- Timelords are now successfully infusing almost 100% of blocks.
- Harvester should be a bit more tolerant of some bad plots.

Added

- This is a maintenance release for 1.0.4 to fix a few mostly cosmetic issues. Please refer to the 1.0.4 notes for the substantive plotting changes - for example - in that release.

Changed

- The GUI now calls it an Estimated Time to Win and has enhanced explanations in the tool tip that the estimated time is often not be the actual time. We have some additional improvements we plan to make here in future releases.
- Development installers now handle semver development versions correctly.

Fixed

- Temp space sizes needed for k = 33 and higher were accidentally under-reported. The values we have placed into the GUI may be conservative in being too large and appreciate feedback from the community on the new optimal temp space needed and RAM choices.
- The GUI plotting progress bar was reaching 100% too early. Thanks to davidbb for the PR.
- Help -> About was blank.
- Our estimate for k=32 was about 0.4GiB too low in some cases.
- Building the GUI in especially ARM64 Linux was painful enough to be considered broken.

Added

- Starting approximately April 21, 2021, the GUI will notify you that this version will stop working at block height 193,536 and will persistently warn you from that block on that you can not use this version (or any earlier version) to farm. This is to support the upgrade to the transaction fork.
- We now have translations for Brazilian Portuguese, Australian English, and Pirate. Thanks to fsavaget, darkflare, maahhh, harold_257, kontin, and GunnlaugurCalvi. Yarr - don't be losing your 24 word treasure map...

Changed

- The plotter in bitfield mode is much improved in plotting speed (~15% faster than in 1.0.3), now requires 28% less temporary space (238.3 GiB/256 GB), and now uses its maximum memory in phase 1 and only needs 3389MiB for optimal sorting of a k32. Total writes should also be down by about 20%. On almost all machines we expect bitfield to be as fast or faster. For CPUs that predate the [Nehalem architecture](<https://en.wikipedia.org/wiki/Nehalem_(microarchitecture)>), bitfield plotting will not work and you will need to use no bitfield. Those CPUs were generally designed before 2010.
- The `src` directory in chia-blockchain has been changed to `chia` to avoid namespace collisions.
- GUI install builds have been simplified to rely on one `.spec` file in `chia/`
- The weight proof timeout can now be configured in config.yaml.
- Peer discovery is now retried more often after you receive initial peers.

Fixed

- We have made significant improvements and bug fixes to stop blockchain and wallet database corruption issues.
- We now pass the environment into the Daemon and this should solve some Windows and MacOS startup bugs.
- The ARM64 .deb installer will now work well on Raspberry Pi OS 64 bit and Ubuntu 18.04 LTS or newer.
- We have made improvements in weight proof generation and saving.
- Wallet start up would have a race condition that output a harmless error on startup.
- Thanks for a typo fix from alfonsoperez.

Added

- This is a minor bug fix release for version 1.0.2
- You should review the [release notes for v1.0.2](https://github.com/Chia-Network/chia-blockchain/releases/tag/1.0.2) but we especially want to point out that wallet sync is much faster than in 1.0.1 and earlier versions.

Fixed

- An incorrect merge brought in unreleased features and broke `chia keys`.
- Omitted from the 1.0.2 changelog, we fixed one crash in harvester with the release of chiapos 1.0.0 as well.

Added

- We have released version 1.0.0 of [chiapos](https://github.com/Chia-Network/chiapos). This includes a 20% speed increase for bitfield plotting compared to the previous version on the same machine. In many cases this will mean that bitfield plotting is as fast or faster than non bitfield plotting.
- xorinox improved our support for RedHat related distributions in `install.sh`.
- ayaseen improved our support for RedHat related distributions in `install-timelord.sh`.
- We have added Dutch and Polish to supported translations. Thanks psydafke, WesleyVH, pieterhauwaerts, bartlomiej.tokarzewski, abstruso, feel.the.code, and Axadiw for contributions to [translations on Crowdin](https://crowdin.com/project/chia-blockchain).
- The GUI now supports "Exclude final directory" when plotting. This is found in the Advanced Options for step 2 on the plot creation page.

Changed

- Wallet now uses a trusted node and, when syncing from that node, Wallet does not do as many validations.
- jespino changed `chia keys show` to require the `--show-mnemonic-seed` before it displays your 24 work private key mnemonic.
- We decreased the size of the block cache in node to perform better with longer chains.
- You can now add a private key mnemonic from a file with `chia keys show`.
- Flofie caught an error in CONTRIBUTING.md.
- We no longer rely on aiter so it has been removed.
- Keyring deprecated the use of OS_X in favor of MacOS.
- "Broken pipe" error was decreased to a warning.
- Many non critical log messages were decreased from warning to info log level.
- Harvester should now log the plot file name if it finds a bad plot at error log level.

Fixed

- Peer ips were being written to the database on a per ip basis. This caused a lot of wasted disk activity and was costing full node performance.
- We fixed an issue where the last block wasn't fetched by the GUI.
- There was an edge case with full node store that can stall syncing.
- There was a potential node locking issue that could have prevented a Timelord from getting a new peak and cause a chain stall.
- We did not correctly support some Crowdin locales. Pirate English was starting to overwrite US English for example.
