Well, according to my logs it has been 878 builds since 20 Nov 2016, when I stated this thread.
That means roughly a master or stable build every 1,7 days 
(I have only edited this thread's first message 690 times, so not all builds have ended up advertised here)
Ps.
Yeah, and so far my router's flash has survived the frequent flashing ok
So it seems both master and 19.07 have ath10k ct variant, is that right?
Meaning master has just newer version of the same driver & firmware?
Assuming the ct variant is superior to the plain ath10k driver.
Is DTS implemented in both 19.07 and master, but only in master is hw based?
Where would you say DTS support is more complete/stable?
I guess DTS feature could be useful to potentionaly be able to use more 5GHz channels.
I tried to measure throughput of 19.07 and I am quite surprised to see it is on par with stock firmware - I assumed that NAT offloading is not implemented (yet) with openwrt or is it?
So I wonder if I did the measurement right.
Or is cpu that fast to do 1Gbit NAT?
Please take performance questions to the generic R7800 exporation thread, which is better suitable for those topics.
But shortly,
Ah, sorry, my misunderstanding, I assumed DFS in place of DTS.
So if there is no r7800 specific significant difference between 19.07 and master - can you mention some general feature available in master only that might be worth to consider to choose master instead of stable branch?
Dear hnyman,
As you said and advised r15204 is working great on both bands wifi. Also - thanks for the heads up on the durability of the router when it comes to frequent flashing. Once again, thanks for your time efforts and geniality. Peace and stay Safe - I will see you here on the thread.
Oh yeah, I do remember you from Dave's thread - and no pressure - just asking - do you - or have you made any of your builds for WRT3200ACM public - or have you continued to not choose that option at this time. I only ask as I saw somewhere that you mentioned you had that hardware - wrt3200acm - and did at times do work with it. Anyway, I am more than pleased with my finding your output here - as " everything " works great.
Half-public something, but not a frequent community build...
(Mwlwifi is crappy abandonware, so I do not take my wrt3200acm that seriously.)
Dear hnyman,
Thanks for the information. I am being encouraged to let others get involved in the conversation - so I am going to go silent for a while. However, thanks for all you do in developing OpenWRT across many platforms.
Peace
now showing error
"Unable to fetch traffic statistic data: JSON.parse: unexpected end of data at line 1 column 16516 of the JSON data"`
I am not sure if this is the right place to ask. It could be a build issue (i.e. different packages used), or just plain understanding. very new to OpenWRT.
I just aquired a R7800 and now want to use this after my modem (AVM fritzbox brand modem-router configured to allow PPPoE from other devices for VDSL).
my ISP says that native ipv6 support is required, and has some information regarding openwrt specifically:
How can I enable IPv6 on a router with OpenWRT?
The following steps describe only the configuration of IPv6 access, but not the setup and configuration of a packet filter (iptables)!
To set up IPv6 on a router with OpenWRT operating system (version 'Attitude Adjustment'), some packages have to be (re)installed first as follows:
opkg update
opkg install kmod-ipv6
opkg install wide-dhcpv6-client
opkg install radvd
The package 'kmod-ipv6' activates IPv6 support in general, 'wide-dhcpv6-client' is needed for DHCPv6 prefix delegation, 'radvd' is used to distribute the IPv6 prefix in the LAN.
Now you can enable IPv6 for the PPPoE connection. To do this, please add the following lines to the configuration of the interface used for PPPoE in '/etc/config/network'.
option ipv6 1
option accept_ra 1
The next PPPoE connection should now already have a /64 prefix, so the PPPoE interface should have a corresponding address. In the next step, please change the configuration in '/etc/config/dhcp6c' to get a /48 for the internal networks using prefix delegation.
To do this, please modify the following lines:
config 'dhcp6c' 'basic' option 'enabled' '1'
config 'interface' 'loopback' option 'enabled' '1' option 'sla_id' '0' option 'sla_len' '16
config 'interface' 'lan' option 'enabled' '1' option 'sla_id' '1' option 'sla_len' '16'
Important are the options for 'sla_len'. They determine which part of the /48 prefix should be used for an internal network. In the last step radvd is configured to distribute the appropriate prefix on the LAN interface via router advertisement.
config interface
option interface 'lan
option ignore 0
config prefix
option interface 'lan
option ignore 0
now since these are different packages, but this build comes with ipv6 packages, I am not sure if all prerequisites are met so that I can use your build on my connection: No matter how I configure, it always comes down to the following error:
Timeout waiting for PADO packets
Unable to complete PPPoE Discovery
From what I understand this could be related to ipv6 configuration. But maybe I have an issue elsewhere?
No. Wrong place.
This thread is about my build for R7800.
Ps. The advice you quoted is hopelessly outdated, as it starts from the year 2012 perspective (Attitude Adjustment). radvd has been deprecated years ago.
All the prerequisites for ipv6 are met with hynman’s build. Feel free to load it and try it out.
Hi,
I have installed this build on my r7800 and I am having wifi performance issues. Mostly, speeds are relatively slow (although I haven't done a proper test) and connections are unstable (dropping out entirely sometimes, but usually the device stays connected and simply can't communicate with any others on the network).
I have tried tweaking usual wireless options (band, transmit power) without much improvement. This seems to be more of a problem with the linux and android based devices on the network than with the windows ones, although I can't confirm that this is the case. The ISP-provided router did not have these issues so I am assuming interference etc are not the problem here.
I would appreciate any help!
I just build 19.07 branch patched with patches from r11250 release and booted the initramfs image, still having stock fw in the flash.
I see following errors on console:

Is this normal/expected?
Or should I assume that the flash contains bad blocks?
The router is brand new, still having the original factory firmware, not flashed with anything yet.
I only disassembled it to attach a serial cable for console access (both covers removed, so I hope the cooler thermo stickers got attached back properly with re-assembly).
You’d do best with opening a thread in the “installing and using openwrt” forum to chase down configuration, router, and client issues.
i can't remember exactly (do a search) but some of these messages (or ones like them) are expected.
dd wrt for r7800 is very stable, any builld by BS since a year and more....
this is not linked with hnyman's build.
probably you are meeting CT drivers. i still can't use them proficiently, even if they are way faster than non-ct one. Try a non-ct build
Hi Hnynam. I have R7800 with Micron MT29F1G08ABBEAH4 same to you. But I had boot loop with all firmware openwrt or stock. I tried your firmware R7800-owrt1907-r11250-ebe8cc2b2a-20201205-1419-factory.img. And log

Could you help me. I think my router has bad block NAND chip. Thanks
Not much help from me, sorry.
Your log looks rather normal until the reboot.
The reboot happens in the middle of wifi firmware load/init. The log seemed to come from the mainline ath10k driver, not the default ath10k-ct wifi driver. (so the log was not from the 19.07 build you mentioned, from apparently from my mainline ath10k master build)
Could be that the wifi chips are somehow faulty in your unit, as you seem to have difficulties with many different firmwares.
Thanks. I used tftp R7800 initramf -> bootm and It loaded openwrt luci --> Update: r7800 squashfs upgrade. And it reboot and boot loop again. Sorry my bad English
