Sphider 4.0.0-MB, SphiderLite 2.0.0 have been released
18 January 2021 - The backup and restore utilities have been reworked to use MySQL directly. This provides higher dependability than depending on PHP. Also, a limited ability to resume a re-index process which has been interrupted has been introduced. The process to determine page character set has been enhanced. Language file conversion to Unicode has been completed. Obsolete versions of code have been removed and general code cleanup done. Further safeguards against indexing of illegal characters has been implemented. SphiderLite has had more remnants of the full version removed.
SphiderLite 1.3.1 has been released
31 December 2020 - A critical flaw was discovered in the SphiderLite indexing code. This has been corrected in this version. ALL USERS OF PREVIOUS VERSIONS OF SPHIDERLITE ARE URGED TO UPGRADE TO 1.3.1! In addition to fixing this CRITICAL FLAW, SphiderLite has also improved the determination of a page character set, has improved filtering while indexing keywords, and improved removal of emojis.
Sphider 3.6.0-MB and SphiderLite 1.3.0 have been released
26 December 2020 - A potential runaway regular expression resulting in missing titles has been corrected. Crawl performance has been improved by fixing a bug that caused Sphider to try to crawl pages returning codes like 301, 401, 403, and 404. The absence of a robots.txt file on sites being crawled was generating warning errors, and this has been corrected. More potential PHP 8 errors have been averted. More obsolete code has been removed. The MB version now reports when a feed becomes invalid.
SphiderLite 1.2.3 has been released
20 December 2020 - A number of PHP warnings were removed, all of which could have been fatal in PHP 8. Also a minor improvement was made when parsing title tags. This is the companion to yesterday's Sphider-3.5.3-MB release.

Sphider 3.5.2-MB and SphiderLite 1.2.2 have been released
9 December 2020 - It was found that when a search returned results, if a new search was performed which should have found nothing, the previous search was returned! This was corrected.

30 November 2020 - Deprecated code which would have caused an error in PHP 8 was removed. A parsing issue with the robots.txt file was resolved. Two options were removed from the database tab.

Typo corrected in tables.sql
5 July 2020 - A typo was discovered in the tables.sql script for both Sphider aqnd SphiderLite. This has been corrected and any future downloads will reflect the correction.

Line 239 (237 in SphiderLite) in tables.sql is:
ENGINE=InnoDB DEFAULT CHARSET=utf8mb4COLLATE=utf8mb4_general_ci;
It should be:
ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci;

16 May 2019 - A fix was made to correct indexing of words composed of non-English characters.
Sphider 3.1.0-MB and 2.4.2-PDO have been released
15 May 2019 - Sphider 3.1.0-MB replaces both Sphider 2.4.1 and 3.0.0-MB. Like 3.0.0-MB, 3.1.0-MB is multibyte string capabable, but without the requirement for the PHP mbstring extension. If mbstring is present, it will be used. If not, it will be emulated. Several character set encoding issues have been resolved, word recognition improved, more reliable meta description indexing, and presentational improvements have been made. Sphider 2.4.2-PDO has eliminated the possibility of certain UTF-8 characters being misinterpreted as ISO-8859-1. As previously announced, the PDO branch will remain available and critical fixes will be made as needed, but no future product enhancements are planned.
Versions 2.4.1, 2.4.1-PDO, and 3.0.0-MB have been released
29 April 2019 - Sphider 2.4.1 and 2.4.1-PDO are maintenance releases. Primary code changes involve how SQL errors are reported in the event a statement preparation fails. Preparation errors should never occur, but better to have good information in the off-chance it does happen. Also, a coding error introduced in 2.4.0 that prevented indexing from a browser in some instances has been corrected.
Sphider 3.0.0-MB is actually 2.4.1 with one BIG change... String handling is now equipped to handle multi-byte character strings. Since the PHP mbstring extension is used, and some hosts do not always provide this extension, Sphider 3.0.0-MB may not run for everyone. Also, being the beginning of a new approach to indexing and searching, some people may feel more comfortable sticking with what they KNOW will work! We feel this will ultimately prove to be the better way.
Version 2.4.0 Released, Legacy and PDO
10 April 2019 - Sphider 2.4.0 has completely re-worked the settings table, giving a number of new search options. Word stemming has been updated and now works with a number of languages other than English. A number of bugs have been corrected. The selection of search templates has been changed with elimination and replacement for the majority.

Updates discontinued for SQLite and PostgreSQL
1 December 2018 - The decision was made not to produce any new updates for the SQLite and PostgreSQL forks of Sphider. They are frozen at release 2.1.0. There just hasn't been sufficient demand to make the time and effort required to maintain these "novelties" worthwhile. User support will still be provided via the forum.
