Code Review

This pull request introduces the release notes for Kmesh v1.2.0, makes a minor typo correction in the v1.1.0 release notes, and improves the styling of images in blog posts. My review focuses on the new v1.2.0 release notes, where I've identified several areas for improvement to enhance clarity and correctness. These include fixing a typo, ensuring consistent list formatting, correcting section numbering, and updating an inaccurate link text. The other changes appear to be correct.

The link text "Kmesh Release v1.1.0" is inconsistent with the link URL, which points to the v1.2.0 release. Since this blog post is about the v1.2.0 release, the text should be updated to "Kmesh Release v1.2.0".

The selector .blog-post-page .markdown img { width: 100%; } will force every blog image (including small diagrams/icons) to upscale to the full content width, which can noticeably pixelate raster images and can make small inline visuals unusably large. Consider removing width: 100% (keep max-width: 100% + height: auto) and/or scoping “full width” to an opt-in class (e.g., .blog-image--full) so only intended screenshots are expanded.

These two list items use the Unicode bullet character (•) instead of Markdown list syntax (-), which can render inconsistently and won’t be picked up as a proper list by some tooling. Please convert them to standard Markdown list items for consistency with the rest of the post.

Section numbering is inconsistent here: this is labeled "### 3" but the previous section is already "### 3. Enhanced ServiceEntry Support". Please renumber this heading (and any subsequent ones if needed) to keep the sequence correct.
