[1.0beta26] aka Beta 1.26 - 2021-02-04

Added

• We now use our own faster primality test based on Baillie-PSW. The new primality test is based on the 2020 paper "Strengthening the Baillie-PSW primality test" by Robert Baillie, Andrew Fiori, Samuel S. Wagstaff Jr. The new test works approximately 20% faster than GMP library's mpz_probab_prime_p() function when generating random 1024-bit primes. This lowers the load on Timelords and speeds up VDF verifications in full node.
• The GUI now checks for an an already running GUI and stops the second launch. Thank you for that PR to @dkackman !
• Transactions are now validated in a separate process in full node.
• chia plots check -l will list all duplicate plot IDs found on the machine. Thanks very much for this PR @eFishCent.

Changed

• Significant improvements have been made to how the full node handles the mempool. This generally cuts CPU usage of node by 2x or more. Part of this increase is that we have temporarily limited the size of transactions. If you want to test sending a transaction you should keep the value of your transaction below 20 TXCH as new consensus will cause you to use a lot of inputs. This will be returned to the expected level as soon as the integration of clvm rust is complete.
• We have changed the way TLS between nodes and between chia services work. Each node now has two certificate authorities. One if a public, shared CA that signs the TLS certificates that every node uses to connect to other nodes on 8444 or 58444. You now also have a self generated private CA that must sign e.g. farmer and harvester's certificates. To run a remote harvester you need a new harvester key that is then signed by your private CA. We know this is not easy for remote harvester in this release but will address it quickly.
• We have changed the way we compile the proof of space plotter and added one additional optimization. On many modern processors this will mean that using the plotter with the -e flag will be 2-3% faster than the Beta 17 plotter on the same CPU. We have found this to be very sensitive to different CPUs but are now confident that, at worst, the Beta 24 plotter with -e will be the same speed as Beta 17 if not slightly faster on the same hardware.
• If a peer is not responsive during sync, node will disconnect it.
• Peers that have not sent data in the last hour are now disconnected.
• We have made the "Help Translate" button in the GUI open in your default web browser and added instructions for adding new translations and more phrases in existing translations at that URL. Try the "Help Translate" option on the language selection pull down to the left of the dark/light mode selection at the top right of the GUI.
• Sync store now tracks all connected peers and removes them as they get removed.
• The Rate Limited Wallet has been ported to new consensus and updated Chialisp methods.
• We are down to only one sub dependency that does not ship binary wheels for all four platforms. The only platform still impacted is ARM64 (generally Raspberry Pi) but that only means that you still need the minor build tools as outlined on the wiki.
• We upgraded to Electron 9.4.2 for the GUI.
• We have upgraded to py-setproctitle 1.2.2. We now have binary wheels for setproctitle on all four platforms and make it a requirement in setup.py. It is run-time optional if you wish to disable it.

Fixed

• On the Farm page of the GUI Latest Block Challenge is now populated. This shows you the actual challenge that came from the Timelord. Index is the signage point index in the current slot. There are 64 signage points every 10 minutes on average where 32 sub blocks can be won.
• Last Attempted Proof is now fixed. This will show you the last time one of your plots passed the plot filter.
• Plot filename is now back in the Plots table of the GUI.
• There was a bug in adding a sub block to weight proofs and an issue in the weight proof index.
• Over time the node would think that there were no peers attached with peak sub block heights higher than 0.
• There was a potential bug in Python 3.9.0 that required us to update blspy, chiapos, chiavdf, and chiabip158.
• An off by one issue could cause syncing to ask for 1 sub block when it should ask for e.g. 32.
• Short sync and backtrack sync both had various issues.
• There was an edge case in bip158 handling.

Known issues

• There is a remaining sync disconnect issue where your synced node will stop hearing responses from the network even though it still gets a few peaks and then stalls. Restarting node should let you quickly short sync back to the blockchain tip.
• Interaction between GitHub Actions changes we made and setuptools_scm meant we had to skip Beta 24 and Beta 25 release tags.
• On the "block" page in the full node GUI, the farmer and pool reward amounts are incorrect, the actual number is the one that is displayed, divided by 8.
