     5  # Upgrading from Tendermint Core
     6  
     7  CometBFT was originally forked from [Tendermint Core v0.34.24][v03424] and
     8  subsequently updated in Informal Systems' public fork of Tendermint Core for
     9  [v0.34.25][v03425] and [v0.34.26][v03426].
    10  
    11  If you already make use of Tendermint Core (either the original Tendermint Core
    12  v0.34.24, or Informal Systems' public fork), you can upgrade to CometBFT
    13  v0.34.27 by replacing your dependency in your `go.mod` file:
    14  
    15  ```bash
    16  go mod edit -replace github.com/cometbft/cometbft=github.com/cometbft/cometbft@v0.34.27
    17  ```
    18  
    19  We make use of the original module URL in order to minimize the impact of
    20  switching to CometBFT. This is only possible in our v0.34 release series, and we
    21  will be switching our module URL to `github.com/cometbft/cometbft` in the next
    22  major release.
    23  
    24  ## Home directory
    25  
    26  CometBFT, by default, will consider its home directory in `~/.cometbft` from now
    27  on instead of `~/.tendermint`.
    28  
    29  ## Environment variables
    30  
    31  The environment variable prefixes have now changed from `TM` to `CMT`. For
    32  example, `TMHOME` or `TM_HOME` become `CMTHOME` or `CMT_HOME`.
    33  
    34  We have implemented a fallback check in case `TMHOME` is still set and `CMTHOME`
    35  is not, but you will start to see a warning message in the logs if the old
    36  `TMHOME` variable is set. This fallback check will be removed entirely in a
    37  subsequent major release of CometBFT.
    38  
    39  ## Building CometBFT
    40  
    41  If you are building CometBFT from scratch, pls observe that it must be compiled 
    42  using Go 1.19 or higher. The use of Go 1.18 is not supported, since this version 
    43  has reached end-of-life with the release of Go 1.20.
