⚠️ Zcash 1.0.3: Important upgrade for Miners/Pools/Users ⚠️

Zcash 1.0.3 has just been released: https://z.cash/blog/new-release-1.0.3.html

This release contains several important bugfixes, and all users are encouraged to upgrade. One of these bugfixes protects you and the network from a cache invalidation issue that could allow an adversary with sufficient resources to cause a denial of service attack or chain fork.


Mac users, ICYMI, I've also updated my fork to track v1.0.3:


Kudos core devs, this is an important update with all the fixes it has...looking forward to v1.0.4


I think autoupdate option will be great to be added in the future, also with the option to enable or disable.

So in the meantime
What is the correct way to upgrade under linux
installed from github

1)update local repository
2)make uninstall?

Here's how to upgrade for the Mac build.

cd zcash
git checkout v1.0.3-mac-gcc

For linux: (need someone to verify)
cd zcash
git checkout v1.0.3
./zcutil/build.sh -j$(nproc)

To see the different versions available for the checkout command
git fetch -v

I got an error on Ubuntu 16.04. Weird since I had no problem upgrading to v1.0.2

mv -f script/.deps/libzcashconsensus_la-interpreter.Tpo script/.deps/libzcashconsensus_la-interpreter.Plo
make[2]: Leaving directory '/home/****/zcash/src'
Makefile:7457: recipe for target 'all-recursive' failed
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory '/home/****/zcash/src'
Makefile:676: recipe for target 'all-recursive' failed
make: *** [all-recursive] Error 1

Try this:
git clean -f -x -d .
./zcutil/build.sh -j$(nproc)

In my main nheqminer folder, I ran git clean -f -x -d . but when I go to run the second line of code, ./zcutild/build.sh -j$(nproc) it says that there is no such file or directory. Which directory should I be in when I run the second line of code?

Scratch that - had to be in my zcash folder.


it didn't work.... This is giving me a head ache man

@guizmo what other errors appear before what you posted when you run ./zcutil/build.sh?

Solved. I'm actually a bit embarrased.... It was a permissions issue. Just needed sudo. That's it.

Thank you @ebfull and @fibonacci for your time.
