Fixed Issues
Known Issues
- [MMALIB-564] MMALIB_CNN_convolveBias_row: 1x1s2 produces more output than requested (execInArgs subMChannel issue)
- [MMALIB-565] MMALIB_CNN_convolveBias_row: row flow handle may not start in the middle of the left virtual pad
- [MMALIB-566] MMALIB_CNN_convolve_col_smallNo_ixX_ixX_oxX produces incorrect output when virtual pad is greater than the panel size
- [MMALIB-571] MMALIB_CNN_convolveBias_row_ixX_ixX_oxX_exec_cn may produce wrong last row when padBottom = 1
- [MMALIB-572] MMALIB_CNN_convolveBias_row_ixX_ixX_oxX_exec_ci: incorrect output for CI when dilated pad greater than input width
- [MMALIB-612] Divergent behaviour between NatC and CI mode when execInArgs set

Package Versioning
Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b [M.m.p.b]. The table below provides a descriptive reference regarding package version numbering.
| Digit | Meaning | Description |
|---|---|---|
| 1 (M=Major) | Major revision | Incremented when the new version is substantially different from the previous For example, a new module added or an existing module's algorithm significantly altered. |
| 2 (m=minor) | Minor revision | Incremented when the new version has changed but not in a major way. For example, some minor changes in the API or feature set. |
| 3 (p=patch) | Patch number | Incremented for all other source code changes. This include any packaging support code. |
| 4 (b=build) | Build number | Incremented for each release delivery to CM. Reset for any change to M, m or p |
