# cubar 0.6.0

- Add util functions (
`codon_optimize`

&
`codon_diff`

)
- Fix url failure of gtRNAdb, which caused remove of cubar from cran
:(

# cubar 0.5.1

- fix a bug in
`get_cscg`

that caused an error when the
input codon frequency matrix has a single row.
- finish unit tests for all functions and internal data.

# cubar 0.5.0

- fixed a bug in
`est_trna_weight`

. Now zero w values were
replaced with geometric mean (rather than the arithmetic mean) of
non-zero w values.
- fixed unexpected warnings in
`est_optimal_codons`

.
- fixed bugs that update input codon table due to
`data.table`

reference semantics.
- added a new vignette explaining the mathematical details of
implementation.

# cubar 0.4.2

- adjust formatting
- fix a typo in
`get_enc`

code

# cubar 0.4.1
