where i can download new wallet?
Here you can get all precompiled wallets for your OS or even the source code.
https://github.com/PIVX-Project/PIVX/releasesMost interesting part is the conversion from Piv to zPiv
edit: as mentioned by Fuzzballs - 3.0 is a Mandatory Upgrade - till 16th October is time to upgrade.
After 16th older wallets won't mint and secure the network anymore and have to update + make a full resync.
Due to security reasons always check any downloaded wallets with the checksums from the Developer. (e.g. electrum-ltc delivers MD5 and SHA256 hashes)
With PivX, the developer hosts the SHA256SUMS.asc file. Download it and run your hashing programm to check whether the pivx-3.0.0.-wallet.zip is fully downloaded and unmodified.
on Linux:
open a terminal within the Download folder where pivx-3.0.0.-wallet.tar.gz + SHA256SUMS.asc are and type:
sha256sum -c SHA256SUMS.asc
and the whole file checks for valid files, at the end should be written that your downloaded pivx-3.0.0.-wallet.tar.gz is OK (just ignore the missing files)
or type in terminal:
sha256sum pivx-3.0.0.-wallet.tar.gz
and check the output with your wallet in the SHA256SUMS.asc file manually.
on Mac
shasum -a 256 pivx-3.0.0.-wallet.tar.gz
and check your output hash manually within the SHA256SUMS.asc file
on Windows
as I know Windows should have CertUtil preinstalled (hope this works still)
Usage description: CertUtil [Options] -hashfile InFile [HashAlgorithm]
CertUtil -hashfile C:\pivx-3.0.0.-wallet.zip SHA256
or download a checksum programme like quick-hash-gui etc...
