Release Notes for version 0.8.30.1

This is performance improvement and stability release.

Performances:

• Page Links window was performing poorly when the crawl session spanned through many sub-domains.
• Page Links window initialization is now faster.
• Slightly sped up fetching all crawl session pages from db.
• Page Links was too slow in case of pages withing sessions with many robots.txt files.
• Deleting a crawl session is now much faster.
• Node selection in trees (Crawl and Index Views) and row selection in Table View is statistically way more responsive.

User Experience / Usability:

• Project db upgrade: when upgrading a project database, the last modified date value is updated.
• Closing a tab while loading a big crawl session no more freezes the application.

Various:

• Setup images updated with the new icon.
• Added HR language menu entry (disabled).

Fixes:

• Fixed real-world crash occurring when hiding in Table View the first column and then selecting an HTTP issue.
• Fixed hypothetical crashing condition (no real user was ever affected) which could occur when visualizing the page links of a page with base attribute pointing to a different sub-domain.
• Fixed real-world crashing condition occurring during crawling when base tag had an empty or missing href attribute.
• Crawl View (link structure), pages with cross-subdomain referrer where in some cases represented under the wrong sub-domain. The fix required an update to the save format, old crawled data would in some cases be represented wrongly while new crawled data will always be represented correctly.
• Fixed a real-world crash occurred when deleting the last crawl session of the list.
• Fixes user experience issue: using tabs in the bottom tools pane fired undesired events selecting nodes in the main panes (note: in some cases it still happens, skip this detail in rel.notes)
• Fixed issue with sorting grids, where in some cases clicking on cells made weird sorting occur (Thanks to J.C. for reporting this issue with a crystal clear video).
• Page Links window column "robots.txt blocked" wasn't evaluating the link against the correct robots.txt file when the link (sub)domain was different from the one of the linking page.
• Fixed crash condition (no real user has been affected) happening when examining links of pages crawled with an older version of the Pigafetta bot.
• Fixed crash condition (no real user has been affected) happening when the user closed a tab while it was loading a big crawl session.
