## 0.97.3 "Exception" (13 Oct 2021)
|
||||||
|
|
||||||
|
This updated version of NeoGo is made to be compatible with Neo 3.0.3 bringing
|
||||||
|
with it all corresponding protocol changes and bug fixes so that you can use
|
||||||
|
it on public testnet and mainnet. It also brings with it a complete
|
||||||
|
experimental P2P state exchange extension for private networks as well as
|
||||||
|
additional optimizations. This is the first version requiring at least Go 1.15
|
||||||
|
to compile, so make sure your Go is up to date if you're not using pre-built
|
||||||
|
binaries. Protocol updates and bug fixes made in this release require a
|
||||||
|
resynchronization on upgrade.
|
||||||
|
|
||||||
|
We also make a final call on Badger and Redis DB issue #2130, if there are no
|
||||||
|
active users of them, support for both will be removed in the next release.
|
||||||
|
|
||||||

||||||
|
sending transaction to RPC node and ask for confirmation (#2180)
|
||||||

* test invocations are now possible for partially-signed transactions stored
|
||||||

|
||||||

|
container (transaction usually) hash (#2192)
|
||||||
|
* out of bounds exceptions can be catched in contracts now for PICKITEM and
|
||||||
|
SETITEM VM instructions (#2209)

|
||||||
|
* configuration parameters specified in seconds no longer use (improper)
|
||||||
|

|
||||||
|
