# Important Notice

**This is a maintenance release. Do not install this over 2.8.0.**

# Highlights

A bug in the 2.6.5 release caused indexer to crash with the following error on Testnet:

```auto
{"error":"error in account type, previously had type lsig but got sig","level":"error","msg":"txn
accounting r=18759726 i=8, error in account type, previously had type lsig but got
sig","time":"2021-12-30T03:33:54Z"}

```

This issue was already fixed in 2.8.0. This hot fix will allow people to continue to run on the 2.6.x release.

# Bug Fixes

- Allow unexpected changes to sig type cache. (#814)
